Effect of fly ash and GGBS on strength and durability of concrete upto 90 days
Shobha Manik Rathod,  Madhulika Sinha
The researchers have started finding alternatives for the partial replacements for cement. This main study of this paper is on investigating the behavior of M20 concrete by partially replacing the cement by Flay Ash and ground granulated blast furnace slag (GGBS). Fly Ash and GGBS is used to make durable concrete structures in combination with ordinary Portland-cement and/or other pozzalanic materials. Cubes are tested for its compressive strength after 28,56 and 90 days of curing. The replacement percentages of cement by Fly Ash and GGBS used are 20 and 30 or 60 and 50 percentages for M20 grade.
