Influence of Waste Tyre Crumb Rubber on Compressive Strength, Static Modulus of Elasticity and Flexural Strength of Concrete

Abstract

Abstract. In this paper, the experimental investigations was carried out to find the compressive strength, static modulus of elasticity and flexural strength of concrete mixtures, in which natural sand was partially replaced with Waste Tyre Crumb Rubber (WTCR). River sand was replaced with five different percentages (5%, 10%, 15%, 20% and 25%) of WTCR by volume. The main objective of the experimental investigation is to find the relationship between static modulus of elasticity and flexural strength with compressive strength of concrete with WTCR. The experimentally obtainedstatic modulus of elasticity and flexural strength results comparing with the theoretical values (various country codes recommendations).

Economic and Environmental Benefit Analysis between Crumb Rubber Concrete and Ordinary Portland Cement Concrete

“…Several works in the literature have recorded experimental data and theoretical views on the mechanical properties of CRC, and the majority of these were published in the past decade. Haridharan et al (2008) [14] verified that the mechanical parameters of CRC (e.g., compressive strength, tensile strength, bending performance, flexural strength, and deflection) decreased on increasing the dosage of rubber particles, substituting the coarse and fine aggregates. However, other experimental results from Isa et al (2014) [15] illustrated that when the volumetric replacement rate of natural aggregates with rubber particles was no more than 4%, the compressive strength and flexural strength of CRC decreased only slightly when compared with ordinary concrete.…”
