  Study on strength and durability characteristics of nano-silica …

  202341 · The inclusion of Nano-silica as a SCM up to certain extent can enhance mechanical and durability properties of concrete. Concrete compressive strength increases as the content of Nano-silica increases. Nano-silica has a very high pozzolanic activity. Filling effect of Nano-silica notably influences the refinement of pore structure.
