Experimental study on Use of Waste Glass as admixture in Concrete

Glass is utilized as a part of numerous structures in everyday life. It has restricted life and after use it is either stock heaped or sent to landfills. Since glass is non-biodegradable, landfills don't give a situation well-disposed arrangement. Thus, there is solid need to use waste glasses. Many efforts has already been made in concrete engineering as a partial replacement of cement or fine aggregate or coarse aggregate. In this experiment we use waste glass powder as a partial replacement of cement and a comparative study has been made with other admixture such as fly ash and silica fume. A series of test were conducted with partial replacement of glass by 15% and 30% to weight of cement where as we have used only 15% of partial replacement in case of fly ash and silica fume just to compare the results with glass at 15% and 30%. The present study demonstrates that waste glass, if ground finer than 100Ã?Â?m demonstrates a pozzolanic conduct. It responds with lime at early time phase of hydration forming extra CSH gel along these lines shaping denser bond matrix. The early utilization of alkalis by glass particles moderate alkali silica reaction consequently expands durability of cement.
