Cement is one of the main component of the building materials, thus its demand is increasing day to day proportionately the emission of carbondioxde is also increasing. Inorder to overcome this, many alternatives are being used these days, one among them is pozzolonic cement which is made of mineral admixtures. Inorder to have a clear knowledge about the pozzolonic action a detailed study is made on the compressive strength of concrete when added with different admixtures. The admixtures used are Metakaolin and Nano silica.(NS) The control concrete is made of 15% of Metakaolin(MK) and the mixes were made by varying the percentage of Nano silica. The Nano silica is used in 0.5% and 1%. The strength are tested for 3rd ,7th and 28th day. The mixes are also tested for its water absorption at the same intervals of 3rd,7th and 28th day.
