Rigid Polyvinyl Chloride Waste for Partial Replacement of Natural Coarse Aggregate in Concrete Mixture

This study aimed at utilizing rigid polyvinyl chloride waste (PVC) for partial replacement of natural coarse aggregate in concrete material. The percentage of PVC waste in the concrete mixture was varied from 0 % to 25 % based on volume of the natural aggregate. The effect of the percentage of PVC on slump, weight, dry density, compressive force of the concrete was investigated. The results showed that the addition of PVC waste to the concrete mixture led to decrease the compressive force of the produced concrete. The reduction in the value of compressive force did not exceed to 4.40%, 12.10%, and 17.57 % when the percentage of PVC was increased to 5%, 10 % and 20%, respectively. The effect of water quantity in the mixture was also studied for the samples contained 5 % PVC. The result proved that the quantity of water had a significant effect on the mechanical properties and the optimum quantity of water for best concrete performance was determined to be 215 kg/m3 under the experimental conditions. The obtained results supported the use of rigid PVC waste for partial replacement of natural aggregate in different civil engineering applications such as pedestrian of road, slopes, public garden corridors, and car parking stations. In addition, the incorporation of the PVC waste in the concrete may decrease the plastic waste disposal cost and impacts
