Natural river sand is expensive due to excessive cost of transportation from natural sources. Also large-scale depletion of these sources creates environmental problems. In such a case non availability of natural fine aggregate and population growth rate in geometric progression has urged the present day engineering society to search an alternative for aggregates to fulfill the basic human need for a shelter. On the other hand Ferro Alloy Silicon Slag, the waste product during the manufacturing process of Ferro- alloys silicon requiring a vast land to be dumped and polluting the environment can be a better substitute for natural fine aggregate i:e natural river sand. Here the objective of the project is the application of slag as a replacement for natural fine aggregate and its effect on mechanical properties of high strength concrete and also self compacting concrete. The paper aims to design concrete with certain target mean strength and to compare the strength of concrete by replacing the natural fine aggregate.
