Using of Glass Wastes as a Fine Aggregate in Concrete Mixture

Abstract

In this study, the waste glass (WG) is considered as a fine aggregate in the concrete mixture. WG is used after grinding to size according to Iraqi sand specifications No.45. The waste glass has been used instead of sand in different proportions, which are 0%, 33%, 66% and 100%. The effects of WG on compressive strength of the concrete and unit weight are analyzed. As results of this study, WG is determined to have a significant effect upon the reduction of its compressive strength and there is a significant decreasing of its unit weight. As for cost analysis, it was determined to lower the cost of concrete production. This study was an environmental one in consideration of the fact that WG could be used in the concrete as fine aggregates without the need for a high cost or rigorous energy.
