Concrete plays a vital role in Infrastructure development of a country and Concrete is the world’s largest consuming material in the field of construction. The replacement of cement through some admixtures or other additives to increase the strength is in trend. Micro silica, a very fine non-crystalline material is very good as filler material to provide good strength. An attempt has been made to increase the strength of concrete by replacing cement with 0%, 5%,10%,15% and 20% of Micro silica in a design mix of M35 and M40.The materials are taken from the locally available sources in the North Eastern region. It is observed that an optimum replacement of 15% of Micro silica to that of cement (by weight) increases the strength of concrete upto 30%.Further addition of micro silica shows a decreasing trend.
