USE OF RECYCLED GLASS IN CONCRETE MIX

Abstract

Now-a-days glass is mostly used in daily life in various forms. As it is a delicate material, it is prone to breakages. Also scraps from various other utilities are also available in abundance. Either it is disposed off or dumped. It is a non-biodegradable material. Use of recycled glass in making concrete mix provides a good environmental friendly solution against its free disposal. Though glass is very prone to alkali-silica reaction (ASR), it’s effect can be prevented by using low alkali content cement. A small amount of metakaolin, chromium oxide, zirconia or lithium also suppresses the (ASR). In the current research work, use of waste glass, in various forms, in concrete mix is done. Glass powder, polishing dust is used for replacement of cement. Fine aggregates and coarse aggregates are also replaced by glass aggregates. Thus, the research aims at environmental friendly utilization of waste glass in concrete making.
