ABSTRACT  Concrete production uses large quantities of natural resources as aggregates and contributes to the release of carbon dioxide during the production of cement. One ton of carbon dioxide is released into the atmosphere for the production of one ton of cement, which is approximately 7% of the world's total yearly production of CO2. Concrete is a common construction material in India and its production causes the same environmental concerns as that of regular concrete. Most of developing country facing shortage of post consumers disposal waste site and it’s become very serious problems. In order to address environmental effects associated with cement manufacturing, there is a need to develop alternative binders to make concrete. Consequently extensive research is on going into the use of cement replacements, using many waste materials and industrial by products. Efforts have been made in the concrete industry to use mixture of fly ash and waste glass as partial replacement of coarse or fine aggregates and cement. In this study, finely powdered fly ash and waste glass powder are used as a partial replacement of cement in concrete and compared it with conventional concrete. This work examines the possibility of using mixture of fly ash and waste glass powder as a partial replacement of cement for new concrete. Mixture of fly ash and waste glass powder was partially replaced as 5%, 10%, 15% and 20% and tested for its compressive and permeability strength up to 52 days of age and were compared with those of conventional concrete; from the results obtained, it is found that mixture of fly ash and waste glass powder can be used as cement replacement material up to particle size less than 75μm to prevent alkali silica reaction.
