| Abstract: | This study presents the use of industrial wastewater released from polyvinyl acetate resin manufacturing plant to totally replace the fresh water in concrete composites. Seventy-two laboratory prepared concrete composites were tested to investigate the effect of using various PVAW/C ratios of 0.30, 0.35, 0.40, and 0.45 on the slump, compressive strength, flexural strength, and dry density of the concrete mixes. Results indicated a slight to moderate increase in compressive strength and hard density values compared to those of the control concrete made with fresh water at 7 and 28 day curing. On the contrary, a reduction in the slump values of the PVAW–concrete was observed compared to the slump of the control mixes. However, the slump values increased with increasing the PVAW/C ratios. On the other hand, the waste material leaching test revealed that none of the PVAW toxic constituents was detected. The findings of this work would form basic information for recycling PVAW in concrete mixes and indicate a potential alternative for diminution the adverse effects on the environment posed by the hazardous effluent of the polyvinyl acetate resin industry. |
