Abstract

This paper investigates the incorporation of crumb rubber from recycled tires into ordinary concrete (OCCR) and dune sand concrete (SCCR), analyzing the effect of incorporation rates ranging from 1% to 5% relative to the sand mass. A comparative study was conducted focusing mainly on apparent density, compactness, mechanical strengths, and the elastic modulus in the linear regime. The results show that the addition of crumb rubber in concrete leads to a reduction in both compressive strength and flexural tensile strength. For an incorporation rate of 3%, Young’s modulus decreases significantly in SCCR compared to OCCR. Specifically, the elastic modulus is E = 24.7 GPa for OCCR and E = 14.23 GPa for SCCR, representing a reduction of approximately 42%.
