Utilisation of Waste Glass Powder in Concrete ? A Literature Review

Bhupendra Singh Shekhawat, Dr. Vanita Aggarwal

Concrete is one of the most widely used construction materials in the world. However, the production of portland cement, an essential constituent of concrete, leads to the release of significant amount of CO2, a greenhouse gas; one ton of portland cement clinker production is said to creates approximately one ton of CO2 and other greenhouse gases (GHGs). Environmental issues are playing an important role in the sustainable development of the cement and concrete industry [Naik and Moriconi, 2005] .There is a need to replace a part of cement by some pozzolanic material to reduce the consumption of cement and the environmental pollution can be checked to some extent. Some of the industrial wastes like fly ash, silica fume, blast furnace slag etc have already established their usage in concrete. Recently the research has shown that the waste glass can be effectively used in concrete either as glass aggregate or as a glass pozzolana. Waste glass when grounded to a very fine powder shows some pozzolanic properties because of silica content. Therefore the glass powder to some extent can replace the cement and contributes for the strength development and also enhances durability characteristics [Chikhalikar S.M. and Tande S.N., 2012]. Demand for recycled glass has considerably decreased in recent years, particularly for mixed-glass. Glass is cheaper to store than to recycle, as conditioners require expenses for the recycling process. There are several alternatives for the reuse of composite-glass. According to previous studies, all these applications, which require pre-conditioning and crushing, are more or less limited and unable to absorb all the quantities of waste glass available. In order to provide a sustainable solution to glass storage, a potential and incentive way would be to reuse this type of glass in concrete [Idir R, 2009].This paper present literature review on replacement of cement by waste glass powder which includes current and future trends of research on the use of crushed glass powder in Portland cement concrete
