Abstract: Today the cost of construction is soaring at an exponential rate with the use of materials like cement, fine aggregate, coarse aggregate. Cement production requires high energy input and also it is generating greenhouse gases. Carbon dioxide is released by cement manufacturing both indirectly (emission of energy) and directly (heating of calcium carbonate). Manufacturing of cement causes emission of the most common greenhouse gas i.e. carbon dioxide, from 5% in cement structures to 8% in case of cement roads. The cement factories produce up to 5% of global artificial emission. Also,  the  prices  of  cement are increasing day by day. The main objective of the concrete industry today is to meet up with the rising demands to perform at its level best to maintain the ecological balance. The excessive emission of greenhouse  gases  inhibits  the  sustainable  growth  of the environment. It has a  greater  impact  on  the  climate  and society. These are the major reasons that the use of high volume replacement of mineral admixtures in cement has gained popularity. Mineral admixtures may be categorized into two groups, namely, chemically active mineral admixtures (Silica Fume and Metakaolin) and micro filler mineral admixtures (Fly ash, Ground Granulated Blast Furnace Slag and Rice Husk  Ash). Replacement of mineral admixtures in concrete leads to substantial environmental benefits. This study emphasizes  on  the usage of high  volume  replacement  of  mineral  admixtures in concrete.
