Effect of nano-silica on strength and durability of fly ash based geopolymer mortar
TLDR
In this paper, an experimental program has been taken up on low calcium fly ash geopolymer mortar having three molar concentrations (8,M, 10,M and 12,M) of activator liquids along with different percentage of nano silica addition (0, 4, 6, 8% and 10% of fly ash).About:
