ANALYSIS OF THE PHYSICAL-MECHANICAL PROPERTIES OF CONCRETE USING RECYCLED PVC AND AGGREGATES

Abstract

Using recycled concrete has gained significant attention as a sustainable solution to reduce the environmental impact of construction waste. However, the mechanical properties of recycled concrete require thorough research to ensure its structural reliability. In this study, the objective was to determine the strength of concrete with PVC. A widely used material in most civil works is PVC, which is used in pipes and accessories for the project's hydro sanitary system. When the work is finished, a lot of PVC waste is discarded and is not recycled. In this research, the physical-mechanical properties of concrete are evaluated, using a dosage where the coarse aggregate is replaced by recycled and crushed PVC, in percentages ranging from 3% to 9%, mainly analyzing its behavior against compression and flexion at the age of 28 days, and obtaining its elastic modulus. The results obtained allow us to determine if the PVC added to the concrete mix gives us favorable results (greater compression and bending strength) or unfavorable results (higher costs, concrete slump, etc.)
