Abstract

This paper presents an experimental result of the damping ratio and related mechanical properties of rubber concrete made by partially replacing the fine aggregate in concrete with rubber powder. The goal is to study the relationship of them with various rubber replacement ratios. First, the effect of the mixing ratio on the mechanical properties, the compression strength and Young's Modulus, of concrete cylinders with different rubber admixtures, including #10 and #40 rubber powders, is discussed. Second, the results of impulse experiments to determine the damping ratios of the rubber concrete cantilever beams are presented. The results reveal that rubber powder increased the damping ratio, and the addition of not more than 7.5% admixture caused at most a 156% increase in the damping ratio with #10 rubber powder, and 194% with #40 rubber powder. Simultaneously, however, the compression strength is reduced by 10-27% with #10 rubber powder, and by 13-41% with #40 rubber powder.
