The behaviour of high strength concrete exposed to high temperature and incorporating Nano SiO₂ and Micro SiO₂ is presented. An experimental programme was developed and carried out which involved testing of Nano SiO₂ and Micro SiO₂ incorporated high strength concrete specimens exposed to temperatures ranging from room temperature to 800°C. Maximum spalling was noted in Micro+Nano silica specimens. However, the maximum strength loss and temperature induced cracking was noticed in Nano silica specimens.
