Supplementary Cementitious Materials are becoming the need of any large scale or sustainable building projects,
hence leading to a rise in popularity of such additives. Alccofine is a new generation micro fine concrete material for high
Strength Concrete which is important in respect of workability as well as strength. Basically, the strength achievement of
structure is the main desire which is fulfilled by addition or partial replacement of Alccofine. The aim of this study is to evaluate
the performance of concrete by partial replacement of cement with Alccofine. Pozzolanic material like Alccofine can be used for
producing highly strength and good quality concrete. In this study cement will be partially replaced by Alccofine for M20 and
M40 grade of concrete. Replacements are to be done at 2.5%, 5% and 7.5% of the weight of cement in concrete. Tests will be
carried out for 3 days, 7 days and 28 days
