在目前的情况下，使混凝土行业可持续发展非常重要，以减少其对环境的不利影响。在选择建筑原材料时，有必要使用环保材料。矿渣微粉是钢铁工业的副产品，具有良好的胶凝性能，可以替代水泥，但水泥对环境造成了严重污染。首先，制备M30等级的混凝土混合物-用0%、10%、20%、30%和40%的GGBS代替水泥。通过抗压试验，筛选出最佳的矿渣置换率。保持该最佳百分比的GGBS恒定，进一步用Alcofine替代水泥，在8%、10%、12%和14%的范围内改变其替代量。计算了这些混合料在7、14和28天的抗压强度等性能。而发现它们的抗压强度值小于常规混凝土混合物的抗压强度值。这证明了矿渣和Alcofine的组合作为水泥的替代品在形成TBC中是无用的，因此需要寻找替代材料。
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.
