The cement industry is one of the main producers of carbon dioxide (CO2).for production of one ton of cement approximately one ton of CO2 is released into the atmosphere. To reduce the cement content different supplementary Cementitious materials (SCM’s) like fly ash, silica fume, alccofine, metakaolin, rice husk ash, ground granulated blast furnace slag were used. In the present investigation SCM’s like silica fume and alccofine were used, In the first stage, cement is partially replaced by silica fume at various percentages such as 5%, 7.5%, and 10% by weight of cement to produce an optimum content of percentage of silica fume. In the second stage, by keeping this optimum percentage of silica fume as constant further cement is replaced by alccofine at 5%, 10% and 15% by weight of cement. The mechanical tests, compressive strength, split tensile strength and flexural strength were studied, besides the durability properties sorptivity, rapid chloride penetration test were studied. The obtained results were compared with conventional concrete.
