This document summarizes research on using shredded rubber tires as a partial replacement for aggregates in concrete. Several studies found that replacing up to 20-25% of aggregates with rubber chips can increase the concrete's elasticity and resistance to cracking while experiencing a 10-30% reduction in compressive strength. Rubber concrete is not suitable for load-bearing structures but can be used in non-structural applications like roads, floors, and parking areas. Using rubber aggregates provides environmental benefits by reusing waste tires and reduces costs by partially replacing traditional aggregates.
