Strength and durability studies on self-curing concrete with bethamcherla stone waste under sulfuric acid attack

Abstract

Concrete is a frequently utilized building material because it is affordable and strong Concrete is ranked second after water due to its widespread use The most widely used building material is concrete, which is also the second most consumed substance globally Aggregates add a major volume to concrete. The aggregates comprise around 70-80% of the volume of the structural concrete, with coarse aggregate (CA) accounting for 40-50% and fine aggregate for 25-30%. Bethamcherla stone at 0%, 10%, 20%, 30%, 40%, and 50% by weight of coarse aggregate is used as coarse aggregate allows us to create a combination that is as economical as possible. Concrete can self-cure by adding polyvinyl alcohol at concentrations of 0.03%, 0.06%, 0.12%, and 0.24%.
