Abstract: This paper reveals mainly about the prime effects of using fly ash, and activated fly ash which is considered to replace cement in concrete, on the concrete strength. For this reason, proper experiments has been done in the lab to investigate the behavior of fly ash and activated fly ash ratio on the strength and workability parameters of concrete. The compressive strength of concrete specimens with replacement ratios of 30% and 40% 50%, and aged 7 and 28 days are measured for M30 as per IS 10262 2009 grade of concrete and are compared with those of the concrete specimens without fly ash. The results shown that strength of partially replaced cement by activated fly ash in concrete enhanced strength is observed and it is slow but strong and continuous process when compared to the concrete without fly ash. And optimum replacement of fly ash ratio can be found out at the maximum compressive tensile and flexural strength of concrete. The main aim of this paper is to study the strength properties of concrete with fly ash and activated fly ash. And compare the results and opt for the best replacement to eliminate more use of cement in concrete.
