Making concrete industry sustainable in the present scenario is very important, so as to reduce its adverse effects on environment. While choosing raw materials for construction it is necessary to go with eco-friendly materials. Alccofine (Ultra fine form of slag) which are by-product from steel industry possess cementitious properties can be used as replacement of cement, which are causing a lot of environmental pollution. Initially, concrete mixes of M30 grade-with replacement of cement by 0%, 10%, 20%, 30% and 40% of GGBS were prepared. They were subjected to compression test so as to select the optimum replacement percentage of GGBS. Keeping this optimum percentage of GGBS as constant, further replacement of cement with Alccofine was done varying its replacement in the range of 8%, 10%, 12% and 14%. The property such as compressive strength of these mixes was computed for 7, 14 and 28 days. whereas their compressive strength values were found to be less than that of the conventional concrete mixes. This goes to prove that the combination of GGBS and Alccofine as replacement for cement would not be useful in the formation of TBC, and hence alternative materials need to be sought for. © 2017 Elsevier Ltd.
