Abstract :

The use of fly ash as a cement replacement makes the mortar less permeable to harmful ions due to its finer particle size distribution and pozzolanic reactions. This results in an enhanced high performance and more durable mortar. Number of studies of the effects of the fly ashes on the behaviour of cement pastes, mortars, and concretes were also carried out. Paper has examined the effect of fly ash used as replacement addition to the Ordinary Portland cement (OPC) on the compressive strength development of cement mortars of five hopper fly ashes at Khaperkheda Thermal Power Plant. The mix proportion 1:3 of cement mortar in which cement is partially replace with fly ash as 0%, 12.5%, 25% and 37.5% by the weight of cement. Compressive strengths of the mortar specimens were determined at 7, 28, and 90 days. Test results show that strength increases with the increase of fly ash up to an optimum value, beyond which, strength values start decreasing with further addition of fly ash.
