  • Weather Effect on Workflow, and Labor Productivity of Construction Plant

    • Authors: Hatim A. Rashid
      Abstract: This study discusses a novel study and develop the important climatic data in Iraq and UAE for changes in construction materials plant  design. It is difficult to identified reliable and microclimate data and related information.  There are many types of construction changes and each type can have an effect on labor and machinery productivity. But what is the  effect of extreme heat and dust storm on construction industry can occurs either indoor or outdoor work. Construction materials production data from United Arab Emirates  region over 2100 productive days period were collected. This study found that the adverse sever summer climate of heat and dust storms lead to a significant reduction in production. An average of week with six  days during summers of heat exceeding 46C with high humidity reduces production in the week by 10% on average. A cross the regional companies, severe weather reduce production on average by 7% and delay the deliveries date. While it is possible that companies are able to recover these losses at some later date of summers. Further, even if recovery does occur at some point at very least these shocks are costly as they increase the volatility of production.  Also this study concludes useful results for assessing the potential productivity shock associate with inclement weather as well as guiding managers on where to locate a new production facility.  We recommend developing of empirical model for Heat Prediction in the region to expect to become more relevant as climate severity and frequent of severe weather.The results of our study also suggest raising the temperature to a more uncomfortable thermal zone lose employers about $2 per worker, per hour,” Keywords: Heat, Dust storm, Productivity, Construction materials

  • Evaluation of Yield of Wells in Ado-Ekiti, Nigeria

    • Authors: P. O. Ale, J. O. Aribisala, M. S. Awopetu
      Abstract: Pumping tests were conducted on twenty selected boreholes and five hand-dug wells cut across Ado Ekiti Metropolitan (AEM) area, with the view to ascertain yield of the wells. Constant rate pumping test and recovery method test were carried out. It was revealled that discharge is directly proportional to the yield of the boreholes and hand-dug wells at a constant drawdown, hence the discharge rate  gives the yield of each of the selected boreholes. The borehole depth ranges between 40 – 120 m while hand-dug well ranges between 3 – 15m. Borehole yield in the AEM area ranged between 0.267 l/s and 2.0 l/s. The yield was not totally dependent on the depths, but also on such parameters as porosity and permeability.  The potential of groundwater in AEM as it relates to quantity is high as all wells yielded water. The average water consumption in litres per person per day for high class income earners was estimated at 196 l/d, while that of low class income earners was 119 l/d. Most residence in AEM depend on ground water for domestic water demand. Possible improvement strategies to groundwater exploitation were highlighted. These improvement strategies and remedies are predrilling geophysical survey before siting of boreholes, monitoring groundwater exploration to avert depletion of groundwater potential zones encouraging sufficient recharge period and conducting regular laboratory tests. Keywords: yield, boreholes, hand-dug wells, recharge, Ado Ekiti.

  • An Experiment to Determine the Effect of Partial Replacement of Natural
           Sand with Manufactured Sand on the Strength of Concrete

    • Authors: Anthony Woode, David Kwame Amoah, Bright Aforla, Freeman Kofi Logah, Maxwell Yaw Dzakah
      Abstract: Natural sand is getting depleted from the environment, because of over exploitation for construction purposes, resulting in loss of vegetation and fertile land for farming. An investigation was, therefore, conducted to determine the suitability of using manufactured sand from crushed gneisses as partial replacement for natural sand for concrete production. In the experiment natural sand was replaced with manufactured sand of the same grading as the natural sand, while keeping all other variables constant. Apart from the control concrete sample which had 100% natural sand all the other samples were treated to 10%, 20%, 30%, 40% and 50% replacement of the natural sand with manufactured sand. Concrete cubes of 150mmx150mmx150mm were made with the various proportions of cement, sand and stones in a mix ratio of 1:2:4, water -cement ratio of 0.45 and cured over 28 days.The results of compressive strength tests show that the strength of the concrete cubes with varying amounts of natural sand and manufactured sand changed marginally. This was interpreted to mean that the partial replacement of natural sand with manufactured sand up to 50% in concrete results in about 6% increase in the strength of the concrete. Manufactured sand, therefore, is regarded as suitable for concrete production on the basis of strength. However, it may affect the concrete in the long run because it contains higher amounts of deleterious substances as compared to the natural sand.

  • Replacing Reinforcing Steel Bars of Continuous Self-Compacting Concrete
           Slabs with Steel Fibers at Intermediate Support

    • Authors: Wissam Kadim Al-Saraj, Nibras Nizar Abduhameed, Hanadi Fadhil Naji
      Abstract: In this paper, the use of  steel fibers instead of the reinforcement steel bars in the continuous self compacted concrete slab panel was experimentally investigated. Tests were carried out on three two-span slab panels under mid span point loads and simply supported at the panels end. The first slab was reinforced by steel bars to resist the negative moments near the internal  supports while the other two slab panels were reinforced by steel fibers only of  percentage of volume fraction (0.5and 1.0) in this zone, without negative steel bars. The load-deflection relationship for the tested slab spans is determined, the first crack load, failure load and deflections were recorded. Also a comparison between the results obtained from this study and that obtained from other study of two continuous slabs made of normal strength concrete (CC) was made , one of these slabs was reinforced by steel bars near the interior supports and the other is reinforced by steel fibers of (1%) in this zone. The test results show that the use of steel fibers instead of the steel bars in the negative moment zone with steel fiber ratio of (VF=1%)  increases the ultimate strength by (39%) and small deflection values at the first loading up to (15kN) while if the steel fiber ratio (VF =0.5%) increases the ultimate capacity by (11.7%) The comparison between the SCC slabs and corresponding CC slabs shows a similar load-deflection curve but the ultimate strength capacity for the SCC slabs with steel fiber gives ultimate strength larger than CC  slabs with steel fibers, while the SCC slabs reinforced by steel bars which show an important effect on the first cracking loading in comparison with CC slabs.

  • Marginal Water Treatment by Combination of Two Stages of Stepped Cascade
           Weir and Spray Aerator

    • Authors: Dheyaa Wajid Abbood, Ayad Sleibi Mustafa, Eitizaz Awad Jasim
      Abstract: A combination of stepped cascade weir with spray aerator systems is one of the available ecological treatments to reduce the concentration of pollutants in marginal water and to solve the problem of the water shortage for irrigation and industrial uses in Iraq. An experimental treatment system for marginal water has been constructed and installed at Al- Mustansiriya University, College of Engineering during the period from August 2013 to July 2014. The performance of the treatment schemes has been evaluated by monitoring the quality of marginal water and effluent for some parameters such as pH, Cl-, BOD5, COD, Fe+2, and Mn+2. Results indicate that the removal efficiencies for COD and BOD5 is ranged from (43% to 51%), and (44%-52%), that the removal efficiency of ions concentrations such as Fe+2, Mn+2, are (30 %-48%) %, and (33% -48%), respectively, while for Cations such as Cl-, the removal efficiency is (31%-42%). Keywords: Marginal water, spray aerator, bio-treatment, stepped cascade weir.

  • Stabilization of Soil with Cassava Peel Ash – Lime Admixture

    • Authors: A.A. Bello, A.E. Ojelade, A. T. Oriaje
      Abstract: This project examined the geotechnical properties of lateritic soils modified with Cassava Peel Ash-Lime admixture with a view to obtaining a cheaper and effective road stabilizer. After collecting samples 1, 2 and 3 from three borrow pits meant for road construction works, preliminary tests was performed on the samples for identification and classification purposes, followed by the consistency limit tests. Engineering property tests (compaction, California bearing ratio (CBR) and Unconfined Compressive Strength) was performed on both at the stabilized and unstabilized states with the addition of 2, 4, 6 and 8% Cassava Peel ash and 1%, 2% and 3% lime contents. The results showed that the soil samples were well graded sand with fair to poor rating as subgrade material for pavement construction. However, the engineering properties of the samples were further improved with the addition of Cassava Peel Ash-Lime Admixture. This caused reductions in the PI of samples 1 from 9% to 1% and 6%. Optimum values of maximum dry densities (MDD) and shear strengths were obtained at 4% for sample 1 and 3, 6% at sample 2 CPA+Lime stabilization. MDD increased to 1.680, 1.680 and 1.920 Mg/m3 respectively in samples A, B and C. We therefore concluded that Cassava Peel Ash-Lime Admixture has a good potential for improving the geotechnical properties of lateritic soils.

  • Assessment of Suitability of Plastic Waste in Bituminous Pavement

    • Authors: Bright Aforla, Anthony Woode, David Kwame Amoah, Samuel Yeboah Baako
      Abstract: The use of plastic products is on the increase daily. The disposal of plastic wastes is a problem in many developing countries like Ghana. These are non-biodegradable products that pose environmental pollution problems to mankind. If these materials can be suitably utilized in road construction, the pollution and disposal problems may be partly reduced.  In recent years, applications of plastic wastes have been considered in road construction with great interest in many developing countries. These plastic wastes are compatible with bitumen at specified conditions. This research aims at determining the suitability of using waste plastic materials as modifiers in bituminous road pavement construction. The waste polymer-bitumen blend was prepared in various proportions and the rheological properties determined in the laboratory. The results indicate that the properties of polymer-modified AC-10 viscosity graded bitumen were enhanced with better binding properties, and can be used in asphalt concrete pavement construction with improved quality and savings. Keywords: Non-Biodegradable, Plastic Waste, Polymer-modified, viscosity graded.

  • Evaluation of Properties of Makurdi Lateritic Clay-Rice Husk Ash Bricks
           for Pavements.

    • Authors: A. M Negedu, T.U Nwakonobi
      Abstract: This study was undertaken to investigate the effect of Rice Husk Ash (RHA) on the burnt properties of the Makurdi lateritic clay. Three (3) to 15 % RHA was blended with the clay. Compressive Strength and Water Absorption test were conducted on each admixture. The clay bricks were burnt at three different temperature levels 7000C, 8000C and 9000C to ascertain the compressive strength property of the clay with temperature variation.  The result showed that the plasticity index reduced gradually and had a minimum value of 19.23% at 9 % RHA. The average compressive strength and water absorption of burnt bricks at 7000C attained a maximum value of 4.79 MN/m2 and minimum value of 16.36 % at 0 % RHA. Keywords: Rice Husk Ash, compressive strength, clay brick, water absorption.
