In the new era, development of high strength concrete demands good amount of cement content which is very exorbitant. Increase in grade of concrete results in escalating the amount of cement quantity. Therefore, by adding small amount of mineral admixtures to the concrete mix can boost the strength of concrete effectively. Focus of this research work is to develop the high strength self compacting concrete which can be self cured. The size of nano silica particles has a great influence on concrete characteristics while comparing it with other nano materials at suitable proportion. The combination of PEG and NS demands an extensive analysis as their contribution towards hydration process is significant. In the present study, Nano silica (NS) was used as mineral admixture, Polyethylene glycol (PEG) was used as self curing agent. Initially optimum content of NS was determined in order to attain the high strength self compacting concrete. Nano silica replaced with cement with the mass of cement and Polyethylene glycol replaced with water by different proportions to the mass of cement. The fresh properties of prescribed mixes satisfies the EFNARC guidelines. Permeability of concrete can be lowered by adopting mineral admixture like NS which helps to overcome chloride ion entry. For which, Durability tests like Rapid Chloride Permeability Test (RCPT) and water absorption and desorption tests were initiated to know the performance of Nano Silica in Self Compacting Concrete. The improved results I,e, optimum content was observed at 2% addition of NS and 3% addition of PEG.
