BEHAVIOR OF RECYCLED GLASS AS FINE AGGREGATE WITH CONCRETE: A REVIEW

Abstract

Increase in population has lead to increase in infrastructure. Availability of sand is continuously being depleted due to the human overexploitation throughout the globe due to rapid urbanization and construction of other amenities, thus the demand of sand as fine aggregate have increased.Use of sand as fine aggregate has triggered lowering of water table,exploitation of natural resource ,erosion of river beds ,sinking of bridge piers ,etc. There is a huge potential to use the waste glass in concrete constructions.The chemical property of waste recycled glass is similar to that of cement due to the presence of SiO2 , Al2O3 ,Fe2O3, Cao. When waste glass is used in concrete constructions production cost will get reduced .By using waste glass in the place of river sand it will be environmental friendly.It Helps in conserving the ecological balance. Glass is widely used in our lives through manufactured products such as sheet glass, bottles, glassware, and vacuum tubing. Glass is an ideal material for recycling which would help in saving energy. This paper deals with the use of waste glass as fine aggregate by replacing sand. A detailed study has been conducted on the variation of compressive strength in concrete due to waste glass used as partial replacement of fine aggregate by weight. This also deals with the effect on workability and ASR due to the presence of glass in concrete .Glass is found to be an ideal material because of its satisfactory performances and aesthetic property improvement. This will additionally solve the problem of overflowing landfills and give a complete new idea for sustainable building.
