  • The Most Suitable Office Chair Alternative For Drafting Studios: The
           Sample of Bartın University Landscape Architecture Department

    • Authors: Erol İMREN
      Abstract: In today’s drafting areas the design of interior elements in line with ergonomical criteria holds great importance from physiological and psychological aspects. Especially the chairs and desks, used by the students who spend most of their times in schools, should be designed in line with ergonomical criteria. In this study, a survey study was carried out with undergraduate students of Bartin University Landscape Architecture Department to determine their demands and requests on the issue. The AHP (Analytic Hierarchy Process) model was built in accordance with the user demands and requests, and accordingly the main and sub-factors of the model were determined as a means to make the most suitable chair selection for use in draft studios. According to the outcomes of AHP model, ergonomy (77%), economy (16%) and aesthetics (7%) were found to be the main effective factors in chair selection. Also, the chairs with adjustment function, armrest and lumbar support were determined as the most suitable ones for use in draft areas. In the results section of the study, the most suitable chair features for use in draft rooms, as well as suggestions for future studies are proposed.

  • Development of Spectral Library for The Fast-Growing Species in Turkey:
           The Poplar Species Case

    • Authors: Ayhan ATEŞOĞLU; Taşkın KAVZOĞLU, İsmail ÇÖLKESEN, Şeyma ÖZLÜSOYLU, Hasan TONBUL, Elif Özlem YILMAZ, Muhammed Yusuf ÖZTÜRK
      Abstract: In recent years, fast-growing species and clones, grown with different production techniques and systems, has a great importance in meeting the wood raw material supply. In this context, industrial plantations are created on a large scale by using poplar species and their clones in the world and in Turkey. The separation of poplar species in Turkey, the determination of their distribution areas and their monitoring form the basis for future wood raw material management and planning. Lately, the preferred and widely used approach for monitoring forest areas is the integration of remote sensing and geographic information systems. In order to distinguish poplar growing sites from the growing areas of other species and to make spatial determination, it is necessary to know their spectral characteristics. The relationship between the energy and object is defined as the spectral signature of the objects, and it is the main data source used to distinguish objects with different spectral properties over the image. Within the scope of this study, spectral measurements were taken for clones Populus deltoides Bartr. “Samsun (I-77/51)”, Populus x euramericana “I-214”, Populus x euramericana “I-45/51”, Populus nigra L. “Kocabey (TR-77/10)” and species Populus nigra L. (Karakavak) with the help of spectroradiometer device in the sampling areas determined in Sakarya-Akyazı, Uşak-Sivaslı, Afyonkarahisar-Çay ve Kırşehir-Özbağ districts, which contain different industrial poplar species and clones. It was determined that all poplar species and clones have similar spectral characteristics in the blue band of the 380-720 nm wavelength range, but there were differences in spectral reflectance values in the green and red/red-edge bands. It was also observed that Populus nigra L. “Kocabey (TR 77/10)” clone could be more effectively distinguished than the others, especially in the infrared region of the electromagnetic spectrum. In the short-wave infrared region of the electromagnetic spectrum, species and clones that cannot be distinguished in the visible or near-infrared region can be distinguished due to the differentiation of their clonal spectral characteristics.

           Containerized Seedlings of Taurus Cedar (Çankırı Forest Nursery)

    • Authors: Sezgin AYAN; Fatma ÇELEN, Bora İMAL
      Abstract: Seedling quality is a major tool in adaptation at plantation sites for Taurus cedar (Cedrus libani A. Rich.), which tends to expand its potential distribution area thanks to the effect of climate change. For this purpo-se; in this study conducted on the seedlings of Mersin-Mut origin with polyethylene bags in the ecological conditions of Çankırı state forest nursery; i) Periodic changes in morphological and physiological seedling characteristics, ii) Morphological seedling characteristics and their compliance with Turkish Standards by the end of the second vegetation period, iii) proposing appropriate nursery cultural operations for the stages of seedling growth have been aimed. As a result of research; 2+0 aged seedlings height (SH), root collar diameter (RCD), the stem fresh weight (SFW), root fresh weight (RFW), the fresh total weight of the seedlings (STFW), the stem dry weight (SDW), root dry weight (RDW), seedling total dry weight (STDW), the ratio of the stem dry weight to root dry weight (KI), the ratio of seedling height to root collar diameter (GI), dry root percentage (DRP%) and Dickson quality index (DQI), it has been determined as follows; 18.57±0.316 cm, 4.9±0.053 mm, 7.86±0.436 g, 7.57±.291 g, 14.63±0.612 g, 3.82±0.256 g, 3.69±0.183 g, 7.21±0.733 g, 1.09±0.042, 30.7±0.718, 55.31%±1.355 and 1.67±0.059 respectively. The Ψmd values of the seedlings showed seasonal changes and decreased in the months when there was low rainfall. The lowest values were found July and September with -1.84 and -2.25 MPa, respectively, and the highest value of -1.39 MPa was found in April. The lowest Fv/Fm value was found in March with 0.57 and the highest in July with 0.81. According to the method of” daily dry matter change"; from March 15th to April 15th is “exit of dormant stage”; from May 15th to July 15th is “growing+fast growing stage”; from July 15th to August 15th is “deceleration stage”; and from September 15th to October 15th has been determined as the “lignification stage” as the stages of seedling development. The highest increase in dry matter occurred during the “growing+fast growing stage” (35.96 mg/day), while the lowest increase in dry matter (5.06 mg/day) was detected during the “exit from dormant stage”.

  • Altitude-Related Morphological and Anatomical Properties in Kazdağı Fir
           (Abies nordmanniana (Stev.) subsp. equi-trojani (Aschers. & Sint. ex
           Boiss) Coode et Cullen) Wood

    • Authors: Eda Nur YILDIZ; Seray ÖZDEN KELEŞ
      Abstract: Turkey is a rich country due to both plant biodiversity and endemism compared to European countries. In this study, therefore, the relationships between the morphological and anatomical properties of Kazdağı fir, one of the most important endemic species of Turkey, at two different altitudes (average 1200 m and 1600 m) were investigated comparatively. Morphological and anatomical properties of a total of 200 trees, aged 30-40 years on average, were determined from each elevation step. Among the morphological characters, the diameter values of the tree at height and breast height and the annual ring width and anatomical characteristics values on the discs extracted from the breast height were determined. For anatomical properties, tracheid length and width, tracheid cell wall thickness, tracheid lumen width, height and width of the rays and the number of rays per 1 mm were calculated. We found that fir trees which grow at low altitude (average 1200 m) showed taller height and thicker diameter in their stems. Average annual ring width, tracheid lumen width and ray width values also showed greater values in fir trees at 1200 m than in fir trees at 1600 m altitude. However, the average length and width of tracheids were higher in fir trees at 1600 m altitude than in fir trees at 1200 m altitude. This study could thus provide a basis for the related studies by providing data on the morphological and wood anatomy studies of Kazdağı fir, which is an endemic species for Turkey, at different altitudes and can make important contributions in this sense.

  • Temporal Analysis of Land Use Change and Urbanization Pressure on Fresh
           Water Producing Watersheds: Büyükçekmece Watershed Case

    • Authors: Betül UYGUR ERDOĞAN
      Abstract: Turkey is located in the Mediterranean basin and expected to encounter with some problems associated with negative effects of climate change in the future. One of the most important problems is related to the quantity and quality of fresh water resources. Our country, which is experiencing water stress, needs to protect its existing water resources against adverse effects of climate change within the framework of sustainable planning. For this reason, it is important to make management plans of water resources on a watershed scale. Today, expansion of the city of Istanbul takes place in watersheds and it carries this situation to even more serious dimensions. In this study, the temporal change of Land Use/Land Cover (LU/LC) patterns and urbanization pressure on Büyükçekmece Lake Watershed, one of the drinking water sources of Istanbul, was studied. In this context, considering the watershed protection zones, the CORINE Land Use/Land Cover (LU/LC) patterns of the watershed between 1990 and 2018 years were determined and their temporal changes were evaluated. While the urban area in the watershed was 4.3% in 1990, this percentage increased to 8.7% in 2018. The increase in urbanization in the watershed and especially in the protection zones have a negative impact on the hydrological processes of the watershed. In order to avoid these consequences, the ecosystem integrity of Büyükçekmece Lake Watershed should be protected. Changes in land use affecting water resources should not be tolerated. In this regard, it should be ensured that the existing legal regulations, inspection and sanction mechanisms take place in practice.

  • Investigation of the Success of Natural Regeneration Fields by
           Multi-Criteria Decision Making Technique

    • Authors: Erol İMREN; Halil Barış ÖZEL
      Abstract: Natural regeneration management is one of the most important steps of silvicultural practices, and it is important for the short-term regeneration of forests that have completed their natural cycles. Sustainability of forests is possible with the correct determination of the problems and the implementation of the correct plans. In this study, the most successfully assessed area has proven to be accurately determinable with the PROMETHEE method, which is an effective ranking method that works by taking numerical data from the determined trial areas in the natural Scotch pine (Pinus sylvestris L.) regeneration area of a forest management directorate. Among the criteria used in the numerical method, we can find the average height, average root neck diameter, and an average number of natural youths. For these criteria, weighting was done with the help of the entropy method. Within the scope of these findings, it has been seen that the success in natural Scotch pine regeneration areas to be realized in other regions is tangibly seen in the numerical data. In addition, this numerical method is important in terms of time efficiency, labor, and economic outputs allocated to these studies.

  • Determination of Carbon Concentration of Tree Components for Stone Pine
           Forests in the Marmara Region

    • Authors: Şükrü Teoman GÜNER; Bilge TUNÇKOL
      Abstract: In accordance with the Kyoto Protocol, countries prepare their national inventory reports (NIR) every year and present it to United Nations Secretariat of the Framework Convention on Climate Change (UNFCCC). These statements are based on AFOLU Guideline (IPCC Guidelines for National Greenhouse Gas Inventories for Agriculture, Forestry and Other Land Use). However, countries are required to produce parameters special to their own tree species in order to make more precise statements. The aim of this study was to determine to calculate both the carbon concentration of various components (needle, wood, bark, and root) of natural stone pine (Pinus pinea L.) and the weighted carbon concentration of above ground and total tree biomass. The study was conducted in natural stone pine forests in Marmara Region of Turkey. Samples were collected in 10 sampling plots that were at mature stage (dbh=20.0-51.9 cm) and had different site characteristics. Site characteristics of the sample plots were determined. Then, needle, wood, bark, and root samples were collected from 3 trees representing the top height in each sampling plot. Carbon analysis on plant samples collected from the sampling plots (10 plots × 3 replications × 4 components = 120 samples) was carried out in the laboratory. The obtained data were evaluated by using analysis of variance and Duncan test. Statistically significant differences were found between carbon concentrations of tree components (P<0.001). The lowest carbon concentrations were in needle (51.65%) and in roots (51.67%), while the highest carbon concentration was in wood (54.74 %) and in barks (54.93%). The weighted carbon concentration for natural stone pine forests were found to be 54.56% and 54.07% for the above-ground biomass and for the total tree biomass, respectively. The carbon concentrations found in this study can be used to calculate the carbon stocks stored in both trees and different components of trees in natural stone pine forests.

  • The Bark and Ambrosia Beetles and Predatory Species Determined in Emirgan
           Grove of Istanbul Province

    • Authors: Gürsel ÇETİN; Pınar HEPHIZLI GÖKSEL, Kibar AK, Oğuzhan SARIKAYA
      Abstract: Forests, which account for a third of the world's land surface, are of vital importance for plenty of living organisms as a natural habitat. In addition to economic contribution, a variety of main characteristics, such as biodiversity, erosion prevention, carbon absorption, sustainability of water resources, landscape and aesthetic appearance increase the crucial value of forests. Forests, which are one of the essential zones that need to be protected for the future of the world, are damaged by many biotic and abiotic factors, and some of them are in danger of extinction. It is known that insects, one of the biotic factors, cause significant damage for some years depending on ecological conditions, and are also vectors of some fungal disease agents. This study was conducted to determine the harmful insects that cause drying in the oak and wild cherry trees in Emirgan Grove of Sarıyer district, one of the most important recreation areas in Istanbul, Turkey's most populous metropolitan city, as well as the beneficial insect species found in this area between 2017 and 2018. Insects that make sawdust on the stems of drying trees, mostly English oak (Quercus robur L.), were obtained from the barks of trunks and galleries, which were up to 2 meters above ground level. Among the insect species obtained, Scolytus mali (Bechstein, 1805), Scolytus scolytus (Fabricius, 1775), Xyleborus monographus (Fabricius, 1792), Xyleborinus saxesenii (Ratzeburg, 1837) (Coleoptera, Curculionidae, Scolytinae), Platypus cylindrus (Fabricius,1792) (Col.: Platypodidae) harmful beetle species, Corticeus fasciatus (Fabricius, 1790) (Coleoptera: Tenebrionidae), Aulonium ruficorne (Olivier, 1790), Colydium elongatum (Fabricius, 1787) (Coleoptera: Colydiidae), Rhizophagus depressus (Fabricius, 1793) (Coleoptera: Rhizophagidae) and Epuraea sp. (Coleoptera: Nitidulidae have been identified as predatory species.

  • Compatible Stem Volume and Stem Diameter Equations for Brutian Pine Stands
           in Antalya-Gebiz Region

    • Authors: Mustafa TURGUT; Ramazan OZÇELİK, Onur ALKAN
      Abstract: Brutian pine (Pinus brutia Ten.) is one of the most important tree species ecologically and economically. Reliable and accurate growth and yield models are needed for sustainable forest management and planning of this species. One of the most important components of the growth and yield models is tree stem volume estimates. Usually, tree volume estimations are still made with single-entry volume tables in Turkey. However, these local volume tables are insufficient for reliable and accurate volume estimation. It is stated that one of the most correct approaches to meet the deficiency in this subject is the use of compatible stem diameter and stem volume equations. In this study, compatible stem diameter and volume equations were developed for Brutian pine trees in Antalya-Gebiz region. For this purpose, parameter estimates were made for the stem diameter and stem volume equations that have been developed by Max and Burkhart (1976), Parresol et al. (1987), Clark et al. (1991), and Jiang et al. (2005). All developed models yielded successful results in both stem diameter and stem volume estimations. The errors in the diameter and volume estimations were found to be less than 2.8 cm and less than 0.02 m3, respectively. In addition, diameter and volume estimates were made at 10 distinct parts of the stem to determine the accuracy and reliability of the models developed. Additionally, the stem volume predictions obtained from proposed models in this study were compared with the volume estimates obtained with the regional volume table, and it was seen that proposed models gave better results than the local volume table. Among the four stem diameter and stem volume models developed, the most successful results were obtained with the model developed by Clark et al. (1991). In addition, the developed models were also compared with the results of local volume table. Tested models produced better results than the local volume table.

  • The Effect of Sampling Design on Data Precision and Practicality in
           Mobile-LiDAR-based Forest Inventories: Case Study from Rize Senyuva

    • Authors: Can VATANDAŞLAR; Mustafa ZEYBEK, Süleyman BORUCU
      Abstract: This study aims to determine an optimal sampling design for forest inventories performed by mobile laser scanners (LiDAR). To this end, the study area, located in Şenyuva Forest Planning Unit, was first surveyed using the conventional ground measurement method by sample plots. Then, it was scanned by mobile LiDAR with different walking routes. Produced point clouds were clipped with different shapes and sizes for feature extraction. Finally, the two datasets were compared for the same stand parameters. Regarding diameter at breast height (DBH), no significant difference was found between the LiDAR data and ground truth (p>0.05) for the entire area (1,834.4 m2). The difference between the datasets was less than 1 cm (~2%) based on the mean of the two data. The number of trees parameter was completely the same and the deviation in dominant tree height was less than 1 m (~1.5%). In conclusion, specific prescriptions were written out for practitioners, surveying different forest conditions. Accordingly, clipping the LiDAR data by 400-m2 circles by scanning the plot from outside is the best option for practitioners who can accept an estimation error of about 10%. The practitioners, who need more precise estimates, should analyze the same data on the entire plot without clipping. If the plot size is greater than 1 ha, scanning within the stand would be necessary.

  • Assessment of Unmanned Aerial Vehicle Use Opportunities in Forest Road
           Project (Düzce Sample)

    • Authors: Mustafa Görkem CİRİTCİOĞLU; Ender BUĞDAY
      Abstract: Forest roads are important infrastructure facilities that enable forestry activities to continue without interruption. These infrastructure facilities are very important in terms of protection and maintenance of forests, safe transportation of the produced property, afforestation, recreation, and transportation to forest fires as soon as possible. Today, an advantageous environment has been created by the widespread use of Geographic Information Systems (GIS) software, the increase in its use, as well as the integration of clearer and reliable information within the framework of sensitive forestry understanding, with the acquisition of high-resolution images with Unmanned Aerial Vehicles (UAV). This study, with the help of UAV data and GIS on forest roads, which serve as the basic infrastructure in the fulfilment of forestry activities, for forest road design and excavation-filling calculations, drones etc. made to demonstrate the applicability of the technologies. The study was carried out on the 164 coded B Type Forest Road belonging to the Cumaova Forestry Directorate affiliated with the Düzce Forestry Operations Directorate. In line with the study, first of all, data were obtained with a multi-copter drone. A Digital Terrain Model (DTM) of the study area was produced with the raw data obtained. The produced DTM data was compared with the 12.5 m Digital Elevation Model (DEM) data showing the land structure before the road was built. At the last stage of the study, the height and position data obtained from the road line with ground measurements and the excavation-fill amounts were compared using the RoadEng software. In the light of the results obtained in this study, it is thought that safer and more precise data can be obtained in forest road design studies, and it can provide a practical approach to road planning studies for planners, decision-makers and practitioners.

  • Investigation the Factors Affecting Risk-Taking Behavior in the Forest
           Products Sector (TR42 Level 2 Region)

    • Authors: Tarık GEDİK; Muhammet ÇİL, Derya SEVİM KORKUT, Mehmet Nurullah KURUTKAN
      Abstract: Since the forest products industry is a labor-intensive that should be considered important in terms of occupational accidents and diseases. In the forest products industry sector, there is a high potential for the emergence of negativities in terms of occupational health and safety due to the working environment’s mechanical, physical, and environmental factors. It will be possible to prevent occupational accidents and diseases by taking the necessary precautions for occupational health and safety in working environments. This study is aimed to examine the factors affecting risk-taking behavior from the perspective of blue-collar (employee) and white-collar (manager) workers in forest products industry sectors operating in the TR42 Level 2 region. For this purpose, 148 different enterprises with 10 or more employees for the forest products industry in the study region and 10835 employees with the number of employees in these enterprises consisted of the universe of the study. Due to the pandemic (Covid-19) process in 2020, 687 participants from a total of 64 different businesses, 36 and 28 of them from furniture and wood & cork products businesses, respectively, were reached through face-to-face interviews. Questionnaires were used as a data collection tool in the study. As a result, white-collar workers think that blue-collar workers tend to take more risks, more importance is given to security-related issues within the enterprise, and working conditions are better within the enterprise. This study will provide guiding information to understand the factors affecting the risk-taking behavior of both white-collar and blue-collar workers.

  • About the Information About Forest and Forest Products in the Islamic
           World in Medieval Sources

    • Authors: Tunay KARAKÖK; Selman KARAYILMAZLAR
      Abstract: With the emergence of humanity, the first human learned to make all kinds of tools and equipment he needed with the goods he obtained from these sources, especially from the forests and the sources that contain nutrients around him, to sustain his life. Thus, the first use of forests and the resources obtained from forest products by humans and the first way of living in forest areas emerged. However, forests in particular were in the position of resources that were used freely and irregularly in the beginning. In time, it has become necessary to determine the ownership status of forests in order to regulate the use of forests by administrative formations created by people and to protect forests. In the course of time, these political or administrative mechanisms have put an end to the concept of common ownership that allows everyone to benefit from forests as they wish. Established states, emirates, or whatever the name is, political mechanisms whose function is to manage societies have even had to include forest areas within the state land structure by the state. However, the increase and spread of settlement units called rural or village, which are called out of city centres, and the pressure of the population on the forests in such places has caused frictions between the villagers and the mechanisms that own the forests.In this study, the Information about Forest and Forest Products in the Islamic World according to the Medieval Sources is presented based on the information within the appropriate sample obtained from the sources of the period by using the qualitative research method. When we look at this information obtained through information and document analysis, it is seen that there are data that support and form the basis for the developments and changes in the relevant field today about forest and forest products in the world of the period. It is another finding that we have products in which forest and forest products are effective in many fields, from architecture to art, from shipping to kitchen tools, from heating to commerce.

  • Evaluation of Marble Waste in Wood Plastic Composites Produced by Flat
           Pressing Method

    • Authors: Sefa DURMAZ
      Abstract: In this study, the evaluation of marble wastes in the production of wood-plastic composites (WPCs) was evaluated. For this purpose, different ratios of marble waste (0, 10, 15, 20, 25, 30) were mixed with wood and plastic to produce WPCs by flat pressing method. The effects of marble waste on some physical and mechanical properties of WPCs were investigated. For this purpose, the WPCs' water absorption and thickness swelling values were examined. The decrease in the wood flour resulted with a better hydrophobic structure. Therefore, increasing marble waste improved the resistance to water absorption and thickness swelling properties significantly. On the contrary, marble wastes caused a decrease in mechanical properties. Reductions up to 26% and 38% occurred in flexural strength and screw withdrawal strength, respectively. The modulus of elasticity first decreased and then increased. The decrease in tensile strength, on the other hand, was more moderate. According to LOI test results, marble waste has also increased the flammability resistance.

  • Table Tennis Blade Production and Features

    • Authors: Avni YILDIZBAŞ; İsmail ÖZLÜSOYLU, Abdullah İSTEK
      Abstract: Table tennis, which emerged in the late 1800s, has changed and developed with equipment development,as in many sports. In the early days, table tennis was played with parchment-covered long-handled rackets and corkor rubber balls. The game started to change with the invention of the hard rubber-coated racket in the 1930s, and thetable tennis racket also changed with the spread of composite materials. A racket blade made of wood can consist ofa single layer, or it mostly consists of 3-7 layers. The racket blade is produced 17 cm long and 15 cm wide on average.However, since there is no limitation in shape, size, and weight in their production, players choose racket bladesaccording to their playing style. According to the International Table Tennis Federation (ITTF) regulations, at least85% of the racket blade thickness must be made of wood, and the surfaces must be smooth and hard. Wood specieswith high impact absorption energy value are more suitable for table tennis blade production. There is an importantrelationship between the vibro-acoustic feature when the racket hits the ball and the racket blade. Density, hardnessresistances, compressive strength, bending resistance, impact absorption energy, vibro-acoustic properties should beknown in determining the suitability of the wood material to be used in the production of table tennis rackets. Varioustree species such as Hinoki, Limba, Balsa, Kiri (Paulownia), Ash, Spruce, Linden, and Walnut are widely used inracket blades production.

           Diseases in Furniture Industry Employees

    • Authors: Ayşin AŞKIN; Ömer Faruk ÖZTÜRK
      Abstract: This study was carried out with the aim of examining work accidents and occupational diseases in furniture industry workers. The data of the study were obtained using survey method (280 questionnaires were included in the study). Istatistical packaged software (SPSS 20) was used for data input and analysis. Descriptive data were presented using mean, standard deviation, frequency, percentage, minimum and maximum values. Chi-Square test was used in the univariate analysis of dependent and independent variables. It was understood that the employees did not use their personal protective equipments regularly and carelessness was the greatest cause of accident. It was determined that they had accidents mainly during the process of cutting. It was determined that there was a significant correlation between age, income status and health problems and the state of having occupational accidents.

  • Determining the Relationships Between Consumers and Furniture Use Time
           Using FP-Growth Algorithm

    • Authors: Eser SÖZEN; Timuçin BARDAK, Selahattin BARDAK
      Abstract: Furniture is widely used by people in all cultures at different times for various purposes in daily life. Furniture and human interaction is an important issue that needs to be examined in many ways. In order to protect the health of consumers and to fully understand their purchasing behavior, information about the life span of furniture is needed. In this study, demographic information of consumers and usage times for different furniture was determined by survey method. Using the Frequent Pattern (FP)-Growth algorithm from the data obtained, the relationship between the usage time of different furniture and the consumers was determined. As a result of the study, it was determined that the strongest association was between those who spent the shortest time on their furniture to eat, being overweight and male. It is another rule of association that those who spend 4 hours a day in work furniture are men with a bachelor's degree. Again, according to the rule of association, the time spent by individuals between the ages of 18-25 in dining furniture was determined as 30 minutes with an accuracy rate of 69%. The proposed method based on data mining shows that the relationships between consumers and the usage time for different furniture can be determined effectively and successfully. Data science can offer decision makers new perspectives to understand consumer behavior. However, there is a need for new studies based on data analysis to increase quality in the furniture industry.

  • Properties of Gypsum Boards Made with Cedrus Tree (Cedrus libani)
           Components. Part 2. Chemical and Technological Properties

    • Authors: Halil Turgut ŞAHİN; Esen ÇAM
      Abstract: In this study, the variation of cedrus tree parts and gypsum during experimental panel manufacturing have been evaluated. The burning pattern on the surface of all test boards produced by adding cedrus’s tree components (wood, bark, cone and needle) as reinforcement fillers to the gypsum structure did not reach the threshold limit of 150 mm that specified in the standard value as ISO 11925-2 standard but only limi-ted spreading of char was observed. It was also found that cone looks like create better barrier against heat compare to needle, wood and bark in similar proportions with gypsum. In contrary, although bark could be absorbed and barrier to heat better than others but it may not support flammability that are not support to mass lost when subject to burning. Some chemical changes occurred in main constituents of lignocellu-losic substances in water/gypsum mixture as evidence with FTIR spectrums. It has also realized that bark (SKa6), cone (Sko6), and needle (SI6) in gypsum negative impact on thermal degradation that higher tempe-rature for decomposition compare to wood-based board (Ska1) at similar experimental manufacturing conditions. It has clearly seen that content of fillers dramatically effects thermal stability of gypsum based boards.
