Abstract
The application of alternative materials in concrete production is getting importance due to rising awareness about sustainable construction. Among alternate materials, recycled waste glass shows good pozzolanic behavior due to its high silica content which makes it an alternate option of cementitious material in concrete. Other physical properties, like-inert nature, positive response against compression etc. and chemical properties make glass an alternative of fine and coarse aggregate too. A critical review on fresh properties and compressive strength of concrete incorporating waste glass has been described in this study based on various published literatures. It has been found from several studies that if waste glass is added in a proper proportion, it is possible to achieve workable concrete with better strength properties than that of regular concrete. Conventional aggregates of concrete, like- gravel, brick chips, sand and cement are expensive, cause extraction of natural resources and environmental pollution. In this context, it can be said that waste glass may introduce an option of economic and pollution free concrete construction if used in optimum quantity.
Highlights
Glass has been serving as a universal packaging container, holding commodities and today, manufacturers use glass to hold everything from soda to perfume (US EPA, 2012)
As per Ismail and Hashmi (2009), the best 28day compressive strength value of 45.9 MPa was obtained from the concrete mix made of 20% waste glass fine aggregate, which represents an increase in the compressive strength of up to 4.23% as compared to the control mix
In the case of 15% addition of glass, there was a decrease of 8% in compressive strength, while there was a decrease of 15% in the compressive
Summary
Glass has been serving as a universal packaging container, holding commodities and today, manufacturers use glass to hold everything from soda to perfume (US EPA, 2012). It was reported that concrete with waste glass powder has a very high workability from control sample and is possible to achieve 30 MPa of compressive strength. Kou and Xing (2012) stated that the flow diameter of concrete decreased with an increase in recycled glass powder and there is a decreasing tendency in early stage of compressive strength and opposite after 28 days. Wang and Huang (2010) used LCD glass partially with fine aggregate in concrete and reported that slump flow increased and compressive strength decreased with an increase in glass percentage. Serniabat et al (2014) used two types of waste glass as entire replacement of coarse aggregate in concrete and reported that 26.8 MPa compressive strength is possible to achieve with glass. The source of glass aggregate used in the research of Keryou (2014) was the waste of windows, collected from local windows glass venders
