Damping Properties of Concrete with Rubber Waste Additives

Abstract

The aim of this research was to investigate the damping properties of hardened concrete with rubber waste additives. Mixtures: one without rubber waste additives (control specimen) and mixtures with different fraction (0/1; 1/2; 2/3) and different amount (5 %; 10 %; 20 %; 30 % from fine aggregate (sand) mass) of rubber waste additives. The influence of rubber waste additive on hardened concrete damping characteristics and strength properties were evaluated. Compressive and flexural strength of concrete decrease with increasing tires rubber waste additive amount was obtained in this study. The addition of rubber waste to concrete decreased the dynamic modulus of elasticity but increased damping decrement of the concrete. The amount of rubber waste had more noticeable effect on concrete damping properties than particles size distribution.
