MIX DESIGN OF FLY-ASH BASED GEOPOLYMER CONCRETE

2021-6-4  FLY ASH Quantity and fineness of fly ash plays an important role in the activation process of geopolymer. It was already pointed out that the strength of geopolymer concrete increases with increase in quantity and fineness of fly ash,. Similarly higher fineness shows higher workability and strength with early duration of heating. So, the main emphasis is given on quantity and fineness of
