摘要

This study was to investigate experimentally the effect of granite aggregate mix composition on vibration characteristics of granite epoxy.50x50x480 mm specimens were cast by making use of five different compositions of granite aggregate with 12.5% resin content and tested for resonant frequency and damping ratio using FFT analyzer. A FG 200 cast iron specimen of the same size was also tested for resonant frequency and damping ratio. To determine the influence of resin content on the damping ratio of granite epoxy, optimized granite aggregate composition (50% fine) from the standpoint of compression strength was utilized to cast two more specimens with 1:6(14%) and 1:8(10%) epoxy to granite ratio by weight and tested for damping ratio.
