To Study Properties of Concrete using Waste Glass Powder as Replacement to Cement

Glass is used in many forms in day-to-day life. It has limited life span and after use it is either stock piled or sent to landfills. Since glass is non-biodegradable, landfills do not provide an environment friendly solution. Hence, there is strong need to utilize waste glasses. Many efforts have been made to use waste glass in concrete industry as a replacement of coarse aggregate, fine aggregate and cement. Now in the present study we are replacing the cement by waste glass powder partially, main constituent of all type glass is silica (SiO2) as large size particle of glass used as the coarse and fine aggregates in concrete but in coarse aggregate replacement has been found to be non-satisfactory because of alkali-silica reaction (ASR). To minimize the ASR which is hazardous to concrete, we used very fine glass powder less than 100µm. So, In present study we are going to focus on use of glass powder (90 µm) as a partial replacement for cement in concrete.
