Effect of Recycling Waste Glass as Fine and Coarse Aggregate on Same Properties of Concrete

Abstract

This research aims to study the possibility of reuse of glass waste as a partial replacement in the first two cases, instead of fine aggregates and weight ratios (5%, 10%, 15%, and 20%) percent, in the second case a partial replacement of the coarse aggregates and the same proportions of the previous weight. The results showed that increasing the content of these wastes replaced by sand Resulted in a decrease in density and an increase in compressive strength at 28 days(16%,18%,27%,22%) respectively. The increase in splitting strength was 28 days (17%, 18.4%, 24.8%, 18%) respectively. The decrease in density was (1.5%,3%,4.4%,6%)respectively. The greatest effect was the compressive strength and splitting strength at 15% the replacement ratio. The results showed that increasing the content of these wastes replaced by gravel Resulted in a decrease in density and an increase in compressive strength at 28 days(12%,14%,16%,11%) respectively. The increase in splitting strength was 28 days (8.4%, 10.4%, 12%,8%) respectively. The decrease in density was(2.8%,4%,5.2%,6.4%)respectively. The greatest effect was the compressive strength and splitting strength at 15% the replacement ratio. The experimental results obtained from the modeling test showed that substituting the sand gave a higher density than replacing the gravel as well as compressive resistance and exhalation higher than gravel replacement.
