Physical and Mechanical Properties of High Strength Concrete containing PVC Waste as a Sand Replacement

Abstract

In this research, physical and mechanical properties of high strength concrete containing PVC waste have been investigated. The fine aggregate was replaced with PVC waste with two different gradings (fine grading and coarse grading) at dosages of 0%, 5%, 10%, 20%, and 40% by the volume of aggregate. The properties include physical properties of density and water absorption, mechanical properties of compressive strength, splitting tensile strength and flexural strength. Results show that in general, using 5% PVC replacement in high strength concrete has no appreciable effect to damage the physical and mechanical properties of concrete. With increasing PVC aggregate content, the deterioration of the concrete properties was observed. The coarse graded PVC aggregate has some more effect on the deterioration of concrete properties compared to the fine graded PVC aggregate.
