This document studies the behavior of concrete when aggregate and sand are replaced with rubber tire chips and foundry sand. Researchers partially replaced coarse aggregate with rubber tire chips and fine aggregate with foundry sand at levels of 10%, 20%, 30%, and 40%. Testing found that rubberized and foundry sand concrete has lower compressive strength than ordinary concrete but is more durable and crack resistant. The study aims to promote the reuse of waste materials like rubber tires and foundry sand in concrete production to improve sustainability.
