  • Abstract:
Structural use of wastes will serve as innovative way of converting wastes to wealth and as efficient mean of waste removal, leading to a cleaner and sustainable environment. This paper presents the results of investigation conducted to determine the effect of water/cement ratio on structural properties of concrete containing polyvinyl waste powder (PWP) as partial replacement of cement. Cement was replaced with PWP up to 40% by weight at interval of 10% for the concrete used for this investigation. The parameters investigated using the water/binder ratio of 0.55, 0.60, 0.65, and 0.70 were: workability, density, compressive strength, and the tensile strength. The result shows that: (i) slump of the specimens increased with the water/binder ratio, (ii) the compressive strengths increased with decreased in water/binder ratio at all the replacement level of cement with PWP, (iii) specimens with 0.55, 0.60, and 0.65 water/binder ratios developed higher compressive strengths when compared to the control specimens up to 20% cement replacement values, (vi) specimens with 0.55, 0.60, and 0.65 water/binder ratios developed higher splitting tensile strength compared to the control sample up to 30% cement replacement polyvinyl waste powder (PWP). It can be concluded that concrete containing PWP up to 20% as a replacement of cement, will develop adequate compressive strength that is acceptable for quality control. However, durability implications of the use of PWP in concrete production should be investigated
