In world concrete is second most consumable material after water, as per record more than 80 million cubic meter volume concrete used every year. And cement is most predominant and key material in concrete as binder and for strength gaining. During manufacturing process of cement large amount of carbon dioxide released in to the atmosphere and it is contribute 18.2% of total only due to manufacturing and infrastructure industries and it is approximately 76% of the anthropogenic Green House Gases contained of carbon dioxide. So it is require to develop green concrete by using the supplementary cementitious material in concrete as alternative. The main objective behind use of sustainable supplementary cementitious material is to reduce the use of cement content without effect on its strength parameter and performance. Ultra High strength concrete contain higher amount of cement compared with other concrete. So reducing cement contain by adding various Supplementary cementitious materials like Ground Granulated Blast Furnace Slag, Fly ash, alccofine, metakaoline etc. up to optimum contain which is not affected the engineering property of UHSC.
