Cement is the chief, expensive and most important ingredient of the concrete mix, while concrete is the second most consumed substance in the world after water. Cement has huge carbon footprint. In production of one ton of cement, approximately one ton of carbon dioxide is released. Global warming and climate change are the major environmental issues raised due to emission of carbon dioxide. The construction industries have a great impact on the environment that contributes to a major part of carbon dioxide emission. . Cement industry is very slow to new thing. A lot of researches are continuously going on the search of new materials that can fully or partially replace cement. Supplementary cementitious materials like fly ash, GGBS, metakaolin, rice husk ash, and silica fume are in the prime focus from last decade. One such abundantly available material is waste glass that can be used in replacement to cement. Reutilization of various wastes resolves the landfill problem and at the same time provides a potential way for use of such materials in construction sector. Glasses are varying in properties so it is difficult to recycle each and every type of waste glass. Only a small fraction of waste glass is reused in production of new glass and the remaining glass are disposed due impurities or color or because of cost .The prime aim of this study is to investigate feasibility of glass powder as partial replacement of cement in cement concrete. M-15 and M-25 grades of concrete were made by partially replacing cement by glass powder in the fraction 0%, 5%, 10%, and 15% and characteristic compressive strength were evaluated. Optimum results were seen at 10% cement replacement with glass powder.
