Influence of PVC waste powder and calcined clay on the properties of concrete

The aim of this study is to report the results of experimental investigation in which varied proportion of polyvinyl chloride waste powder (PWP) are used to partially substitute cement. 10 percent calcined clay was held constant while PVC waste powder (PWP) was altered in the proportion 0%, 5% and 15% by weight of cement in the preparation of test specimens. For testing fresh concrete, the slump test was performed. Curing time of 7, 14, 28 and 56 days was used to explore the fresh properties like slump tests and mechanical characteristics of concrete such as compressive strength, split-tensile strength, and flexural strength. The results of this experiment show that up to 5% PWP and 10% calcined clay may be utilized in M40 grade concrete without impairing the fresh and mechanical qualities of the concrete. By utilizing PWP up to 5% as a partial replacement for cement with fixed calcined clay concentration of 10% found to be advantageous for getting higher strength concrete.
