  • Practicability in the manufacture of non-structural bricks, from the
           recycling of cigarette butts

    • Abstract: Resumen: Las colillas de cigarrillo son uno de los residuos más comunes a nivel mundial. Sus componentes tóxicos y no biodegradables hacen de este un residuo peligroso y una de las causas de contaminación ambiental. Este artículo presenta los resultados de una investigación en la que se estudió la alternativa de incorporar colillas de cigarrillo en la fabricación de ladrillos de arcilla. Se elaboraron cuatro mezclas dentro de las que se incluye una mezcla patrón con contenido de 100% arcilla (LADRICOL 0%) y tres adicionales con colillas de cigarrillo en diferentes porcentajes en peso (LADRICOL 2,5%, LADRICOL 5% y LADRICOL 7,5%). Estas mezclas fueron cocidas a diferentes temperaturas y se sometieron a los ensayos respectivos para determinar propiedades físicas y mecánicas del producto terminado. Los resultados obtenidos, demostraron que, con la adición de colillas de cigarrillo en un 2,5% y una temperatura óptima de cocción de 850°C, se pueden fabricar ladrillos no estructurales tipo M, cumpliendo con los estándares establecidos en la NTC 4205-2, generando impactos positivos en el medio ambiente y reduciendo el consumo energético durante la cocción del ladrillo, en un 19,75% : Cigarette butts are one of the most common waste worldwide. The toxic and non-biodegradable components make cigarette butts a hazardous waste and one of the causes of pollution. This paper presents some of the results of a study on the re-cycling cigarette butts in the manufacture of clay bricks. Four mixtures were made, these include a control clay brick, with a clay content of 100% (LADRICOL 0%) and three additional mixtures incorporating cigarette butts in different percentages by weight (LADRICOL 2.5%, LADRICOL 5.0% and LADRICOL 7.5%). The mixtures were fired at different temperatures and these were tested to determine the physical and mechanical properties of the bricks. The results showed that the samples incorporating 2.5% cigarette butts content and fired at 850 °C are in compliance with the standard normative for this type of product (NTC 4205-2). Furthermore, this brick can improve the environmental quality and can reduce energy consumption during firing, by 19.75%.
       
  • Utilizing Industrial Metal Wastes in One-Way Ribbed Reinforced Concrete
           Panels

    • Abstract: Resumen: La eliminación de los residuos metálicos generados durante los procesos iniciales de fabricación en plantas industriales y talleres con maquinaria sigue siendo un gran problema. La investigación actual se ocupó de agregar los residuos metálicos producidos en el procesamiento de la maquinaria, tales como el polvo de limaduras de hierro, virutas del torno de hierro y del torno de aluminio para mejorar el rendimiento estructural de los paneles de losa nervada unidireccional. En este trabajo se consideraron dos tipos de hormigón: ferrocemento (FER) y hormigón autocompactante (SCC). Los paneles de hormigón armado con polvo de limaduras de hierro y virutas de torno giratorio de hierro mostraron un aumento en la carga máxima y una disminución en la deflexión central, mientras que los paneles con virutas de torno giratorio de aluminio revelaron un comportamiento opuesto. El efecto más significativo del uso de los desechos metálicos es su mejor resistencia a la propagación de las fisuras al aumentar la unión entre las fibras y el mortero de cemento a través de las grietas. El hecho de agregar los desechos metálicos con partículas finas mejora la resistencia del hormigón, siempre que se controle la trabajabilidad. El uso de las virutas de torno como fibra de hierro con un factor de forma específico tiene un efecto secundario debido a la formación de bolas de fibra en la mezcla de hormigón. Además, el uso de altos porcentajes de polvo de limaduras de hierro provoca la aglomeración de las partículas de polvo debido a las fuerzas de atracción magnética. : The elimination of metal waste generated during the initial manufacturing processes of industrial plants and workshop machines still a big problem. The current investigation dealt with adding the metal wastes produced by machinery processing such as iron filings powder, iron turning lathe, and aluminum turning lathe to improve the structural performance of one-way ribbed slab (RS) panels. Two types of concrete were considered in this work; Ferro cement (FER) and self-compacting concrete (SCC). The reinforced concrete panels with iron filings powder and iron turning lathe showed an increase in the ultimate load and a decrease in the central deflection, while the panels with aluminum turning lathe revealed an opposite behavior. The significant effect of using metal wastes is the superior resistance to crack propagation by increase the bond between fibers and cement mortar across the cracks. Adding the metal wastes with fine particles improves the concrete strength providing the workability must be controlled. Using the lathe as an iron fiber with a specific shape factor has a side effect due to fiber balling in the concrete mix. Also, high percentages of filings iron powder cause agglomerate the powder particles due to magnetic attraction forces.
       
  • Comparative seismic analysis of a torsionally-flexible unsymmetric
           structure by applying NSP, MPA, NLRHA

    • Abstract: Resumen: Se verifica la aplicabilidad de los métodos de análisis no lineal: pushover (NSP) y pushover multimodal (MPA) para estructuras torsionalmente flexibles cuyo período de vibración fundamental es mayor a 1s, confrontando los resultados con un análisis de historia de respuesta no lineal (NLRHA). El análisis se aplica a un edificio irregular en planta y elevación de 10 pisos porticado en concreto reforzado construido en los años 70’s. Se construyó un modelo matemático tridimensional basado en elementos finitos, utilizando propiedades no lineales de los materiales en base a los modelos constitutivos de (Mander, 1984) y (Park, 1988) para el concreto y acero respectivamente. La demanda se estableció para el sismo de diseño definido por NEC-SE-DS2015 cuya probabilidad de excedencia es del 10% en 50 años; y para 3 pares de registros sísmicos propiamente seleccionados, ajustados y escalados al espectro de diseño. Se determinó que para estructuras de más de 1s de período de vibración el NSP subestima la capacidad de desplazamiento máximo, puesto que no considera el aporte de los modos de vibración superiores a la respuesta total del sistema. El MPA se ajusta más al NLRHA y es aplicable principalmente en estructuras regulares, pues se generan inconsistencias cuando se presenta un porcentaje de torsión considerable en modos de vibración traslacionales. : The applicability of nonlinear analysis methods pushover (NSP) and multimodal pushover (MPA) is verified for torsionally-flexible structures whose natural vibration period is larger than 1 sec. The results are confronted with a nonlinear response history analysis (NLRHA). The procedure is applied to an irregular 10-story concrete framed structure, built in the ’70s. A mathematical three-dimensional finite element-based model was developed using material properties based on Mander (1984) concrete model and Park (1975) steel model. Seismic hazard is established for the design basis earthquake (DBE) as defined in NEC-SE-DS2015 with a 10% probability of exceedance in 50 years, and for three pairs of ground motions properly matched and scaled to DBE. It was determined that for structures with a 1 sec or more natural vibration period, NSP underestimates the maximum displacement capacity since it does not consider the contribution of higher vibration modes to the total response of the system. MPA fits more to NLRHA and is mainly applicable to regular framed buildings since inconsistencies are generated when a considerable percentage of torsion occurs in translational vibration modes.
       
  • Calibration of an empirical model for moisture content assessment and
           monitoring in compacted tropical soils used in the subgrade of road
           pavements

    • Abstract: Resumen: El monitoreo y control de la variación de la humedad de la subrasante es importante debido a su influencia en el desempeño y vida de servicio del pavimento. La aplicación precisa de técnicas no destructivas, como la reflectometría de dominio del tiempo (TDR) y el radar de penetración terrestre (GPR) en suelos tropicales compactados, dependen de modelos de calibración que consideren su composición mineralógica y propiedades geotécnicas. El presente trabajo tiene como objetivo determinar modelos de calibración que relacionen la permitividad dieléctrica con la variación de humedad en suelos tropicales compactados. La técnica TDR se utilizó con sondas de bajo costo y columnas de calibración desarrolladas en laboratorio para la lectura de la permitividad dieléctrica y definir su relación con la humedad. Los resultados demostraron que, a través de procedimientos estandarizados de laboratorio, es posible determinar modelos de calibración acordes con la precisión requerida en el control de la humedad en la subrasante. Se constató que la alta densidad y las propiedades magnéticas de los suelos tropicales afectaron significativamente la determinación de la permitividad dieléctrica y, en consecuencia, la estimación de la humedad, lo que reafirma la necesidad de calibraciones específicas para este tipo de suelos. : Subgrade moisture variation monitoring and control is important due to its influence on road pavement performance and service life. The precise application of non-invasive techniques such as time domain reflectometry (TDR) and ground penetration radar (GPR) in compacted tropical soils depend on calibration models, that consider their mineralogical composition and geotechnical properties. The present work aims to determine calibration models that relate dielectric permittivity with moisture variation in compacted tropical soils. TDR technique was used with low-cost probes and soil calibration columns developed at laboratory for reading dielectric permittivity and define its relationship with moisture. Results showed that through laboratory standardized procedures, it is possible to determine calibration models according to the required accuracy in moisture control in the subgrade. It was found that the high density and magnetic properties of tropical soils significantly influenced the determination of dielectric permittivity and consequently in moisture estimates, hence reaffirming the need of specific calibrations for these types of soils.
       
  • Comparison addition of rice husk ash and roof tile ash on fly ash-based
           geopolymer cement with portland cement

    • Abstract: Resumen: El cemento Portland se considera un excelente material para la fabricación de hormigón. Por su alto rendimiento en esta elaboración se encuentra mucho en tiendas de construcción. La investigación acerca de cementos Portland alternativos tiene prioridad a nivel mundial para reducir las emisiones de CO a la atmósfera. El cemento Portland alternativo es un material que contiene aluminosilicatos disueltos en una solución alcalina para producir propiedades puzolánicas suficientemente sólidas que reemplacen la función del cemento Portland. Los aluminosilicatos naturales se pueden encontrar en desechos agrícolas e industriales. Por ejemplo, en cenizas volantes (CV), cenizas de tejas (CT), cenizas de cascarilla de arroz (CCAr), cenizas de caña de azúcar (CCAZ). Este método compara el desarrollo de propiedades mecánicas del concreto con cemento Portland alternativo con las del concreto con cemento Portland normal, durante todo el proceso de su empleo. Las propiedades mecánicas que se revisarán son el tiempo de fraguado y la resistencia a la compresión. El cemento Portland alternativo utiliza una base de aluminosilicato de cenizas volantes con una solución alcalina activadora (NaOH, Na2SiO3) 12 molar. Este estudio se basa en ensayos experimentales de reemplazo de CV al 5% y 10% con CCAR y CT, en los que se investigó el desarrollo de varias propiedades mecánicas. Los resultados muestran que varias mezclas alternativas de cemento Portland tienen propiedades mecánicas similares al cemento Portland normal. : The use of Portland cement is considered a very good material for making concrete. This is because many are found in building shops and it's high performance in making concrete. Research on alternative Portland cement is a worldwide priority for reducing CO emissions to the atmosphere. Alternative Portland cement is a material containing aluminosilicate which is dissolved with an alkaline solution to produce strong pozzolanic properties and replace the function of Portland cement. Natural aluminosilicates can be found in agricultural and industrial wastes. For example fly ash (FA), roof tile ash (RTA), rice husk ash (RHA), sugar cane bagasse ash (SCBA). This method estimates the development of mechanical properties of concrete with alternative portland cement with concrete with portland cement throughout the treatment process. The mechanical properties that will be seen are setting time and compressive strength. Alternative Portland cement uses the basic ingredients of fly ash aluminosilicate with an alkaline activator solution (NaOH, Na2SiO3) of 12 Molar. This study is based on experimental studies by replacing FA by 5% and 10% with RHA and RTA where the development of several mechanical properties will be investigated. The results show that several alternative portland cement mixes have similar mechanical properties to portland cement.
       
  • Lightweight concrete masonry blocks produced with:

    • Abstract: Resumen: Este artículo evalúa bloques de mampostería de hormigón liviano, a los cuales se les ha incorporado caucho y metacaolín con el objeto de reducir su densidad aparente y obtener valores dimensionales de resistencia a la compresión y absorción de agua, en conformidad con la norma brasileña (ABNT NBR 6136, 2016). Se fabricaron tres mezclas de hormigón, reemplazando el 9%, 18% y 27% (en volumen) del agregado fino por caucho de neumáticos y además una mezcla sin caucho (referencia). En todas las mezclas, se adoptó el procedimiento de reemplazar el 10% (en peso) de cemento por metacaolín. Los bloques de hormigón del tipo M-15x30 se fabricaron manualmente, utilizando moldes de PVC y elementos de botellas PET para moldear huecos de los bloques. Los resultados indican que los hormigones fabricados con caucho y metacaolín arrojan valores de densidad aparente menores a 2000 kg/m3, presentando así características de hormigón liviano. En cuanto al análisis de las dimensiones, todas las series de bloques producidas cumplieron con los requisitos de la norma vigente. Si bien solo las series R0, R1 y R2 tienen función estructural, todas las mezclas obtuvieron tasas de absorción de agua inferiores al 13%. Por lo tanto, se considera que el caucho de neumáticos como agregado fino en los bloques de hormigón es una buena alternativa para reutilizar este material de desecho. : This paper presents the evaluation of lightweight concrete masonry blocks, incorporated with tire rubber and metakaolin, aiming reduce its bulk density and obtaining dimensional values of compressive strength and water absorption in according to the Brazilian standard (ABNT NBR 6136, 2016). Three mixtures of concrete were produced by the replacement of 9%, 18% and 27% (by volume) of the fine aggregate by tire rubber, and one mixture without rubber (reference). In all mixtures the procedure of replacing 10% (by weight) of cement to metakaolin was adopted. Family M-15x30 of concrete blocks were performed using an entirely manual process, with PVC molds and PET bottle devices to casting the hollow characteristic of blocks. The results indicated that the concretes produced with rubber and metakaolin provided bulk density values lower than 2000 kg/m³, thus featuring lightweight concrete characteristics. In the dimensional verification, all the blocks series produced reached of requirements of the current standard. Although only the R0, R1 and R2 series had structural function, however all mixtures achieved water absorption ratio lower than 13%. Therefore, the tire rubber as fine aggregate in concrete masonry blocks is thought to be a good alternative for reuse of this waste material.

  • Evaluation of the effectiveness of the use of the TDI (Traffic
           Densification Index) for the prediction of the behavior of nano-modified
           asphalt mixtures against permanent deformation

    • Abstract: Resumen: Este artículo muestra los resultados de un estudio sobre la evaluación del uso del índice TDI (Traffic Densification Index) para la predicción del comportamiento de una mezcla asfáltica convencional y dos mezclas asfálticas nanomodificadas (una con 2% de nanotubos de carbono - NTC y otra con 3% de nanoarcilla organofilica - NA) frente a la deformación permanente. Las mezclas fueron diseñadas con granulometrías equivalentes y ligantes asfálticos distintos (un convencional y dos nanomodificados). El diseño de las mezclas fue realizado según el método Superpave y a partir de las curvas obtenidas en el ensayo de compactación (%Gmm vs número de giros) fue determinado el índice TDI de las mezclas. Para cada mezcla estudiada, fueron compactadas dos placas, con dimensiones de 50 x 18 x 5 cm, en la máquina compactadora BBPAC del IFSTTAR (Institut Français des Sciences et Techonologies des Transportes, de L’aménagement et des Réseaux); estas placas fueron, posteriormente, sometidas al ensayo de deformación permanente en el simulador de tráfico francés Orniéreur. El índice TDI obtenido fue comparado con el desempeño de las mezclas en el ensayo de deformación permanente. Los resultados obtenidos indican que el índice TDI no se mostró eficaz al momento de predecir el comportamiento, cuanto a la deformación permanente, de las mezclas asfálticas con ligante asfálticos distintos al convencional (nanomodificados). : This article shows the results of a study on the evaluation of the use of the TDI (Traffic Densification Index) for the prediction of the behavior of a conventional asphalt mixture and two nano-modified asphalt mixtures (one with 2% of carbon nanotubes, CNTs, and another with 3% of organophilic nanoclay, NA) against permanent deformation. The mixtures were designed with equivalent granulometries and different asphalt binders (a conventional and two nano-modified binders). The design of the mixtures was made according to the Superpave method, and the TDI of the mixture was determined from the curves obtained in the compaction test (%Gmm vs number of cycles). For each mixture under study, two slabs measuring 50 x 18 x 5 cm were compacted on the BBPAC slabs compactor of IFSTTAR (Institut Français des Sciences et Technologies des Transports, de L'Aménagement et des Réseaux). These slabs were subsequently subjected to the permanent deformation test in the French traffic simulator, Orniéreur. The TDI obtained was compared with the performance of the mixtures in the permanent deformation test. The results obtained show that the TDI was not effective in predicting the behavior, in terms of permanent deformation, of asphalt mixtures with asphalt binders different from the conventional binder (nano-modified).
       
  • Experimental Evaluation of Square Ferrocement Panels using Polypropylene
           Wire Mesh

    • Abstract: Resumen: Los paneles de ferrocemento están constituidos por una sección delgada de mortero hidráulico reforzado con malla de alambre de acero y están expuestos a que se produzcan microgrietas en condiciones de servicio. La humedad y el agua de lluvia pueden infiltrarse a través de estas grietas y provocar una reducción en su capacidad debido a la corrosión de la malla de alambre de acero. En el presente estudio, se ha utilizado una malla de polipropileno (PP) para superar este problema. El objetivo principal del presente estudio es investigar la capacidad de punzonado y flexión de los paneles de ferrocemento utilizando malla de PP. Se realizaron ensayos experimentales en 32 paneles de losas cuadradas de 450x450 mm con apoyo simple sometidos a carga concentrada por punzonamiento y carga de cuatro puntos para investigar su capacidad de flexión. Las variables experimentales fueron el número de capas de PP (fracción de volumen) y el espesor de la losa, de 20, 30 y 40 mm. Los resultados de las pruebas mostraron que la resistencia a la perforación mejoró al aumentar tanto el número de capas de PP como el grosor del panel. Sin embargo, la resistencia a la flexión es función de la acción de la membrana de tensión proporcionada por las capas exteriores de PP. Además, los paneles con un espesor de 20 mm son demasiado endebles y no muestran una resistencia suficiente. En general, la malla de PP proporciona una resistencia adecuada contra perforaciones y flexiones para losas de 30 mm y 40 mm de espesor, y se puede utilizar como reemplazo de la malla de alambre de acero convencional. : Ferrocement panels are thin section comprised of hydraulic mortar reinforced with steel wire mesh, and are susceptible to micro cracks at service conditions. The moisture and rainwater may infiltrate through these cracks and cause the reduction in capacity due to the corrosion of steel wire mesh. In the present study, a polypropylene (PP) wire mesh has been used to overcome this problem. The main objective of the study is to investigate the punching shear and bending capacity of the ferrocement panels using PP wire mesh. Experimental tests conducted on 32 simply supported square slabs panels of 450x450 mm subjected to concentrated load for punching shear and four-point loading to investigate the bending capacity. The test variables were the number PP layers (volume fraction ratio) and slab thickness i.e., 20, 30 and 40 mm. Test results showed that punching capacity improved by increasing both the number of PP layers and panel thickness. However, bending strength the function of tension membrane action provided by exterior PP layers. Moreover, panels with 20 mm thickness are to flimsy and do not show sufficient capacity. In general, PP wire mesh provide adequate resistance against punching and bending for slab thickness 30mm and 40mm, and can be used as replacement of conventional steel wire mesh.
