Nowadays, sustainability is crucial in preserving and promoting enduring environmental conditions for the benefit of humanity’s well-being. The purpose of this paper is to present anidea on use of artificial replacement for fines so as to declare it as alternative to natural sand and also to fit the line of increasing demand for high performance concrete. With growing needs of finding substitute for fines, cement industry has already raised the beneficial use of supplementary cementitious materials in various combinations and its effect on requiremental aspects of concrete. This paper emphasizes the use of cementitious materials i.e. silica fume and GGBS in trial evolved proportion in combination with natural sand, crushed sand and processed slag sand. With the increasing need of natural cement, the need of evolving the use of steel slag has come in picture. The evolution for sustainability is the need of hour. The Indian standard code permits the use of recycled aggregates in some percent but with the changing environmental conditions this has to be changed.
