The Property of regular cement can be improved by expansion of Nano silica. In this venture nano silica and were utilized with concrete composites to build the properties of cement. The goal of the current examination is to research the conduct of nano silica Modified concrete cement in both new and solidified state. The solid of M25 grade traditional cement is utilized and the nano silica from 0% to 2.5% were utilized. The outcomes acquired are the halfway expansion of nano silica with regular concrete cement up to 1.75% which upgrades the quality of Concrete
