Recycling of Glass in Concrete

Abstract

Glass is widely used in our daily life. It is an ideal material for recycling. Recycling of glass is used in various forms in different fields. One of the important applications of recycling of glass is in concrete production of construction field. In this article, coarse and fine aggregates of concrete had been replaced up to 20 percent by the crushed glass. In depth observation had been done on properties of concrete i.e., compressive strength, flexural strength, air content and also alkali-silica reaction (ASR). Replacement of waste glass (WG); silica in glass and alkalies in cement combined to create large expansion which causes the large cracks in concrete. This is the main disadvantage of usage of waste glass in concrete. We had overcome this problem up to some level by varying the particle size of glass which is also an influencing factor for expansion. We also used some cementitious materials like fly-ash, microsilica along with waste crushed glass. This research is mainly focused on observing mechanical properties of concrete and controlling of alkali-silica reaction.
