Compressive Strength of Cement & Fly Ash Mortar: A Case Study

Abstract

The use of ash as a cement replacement makes the mortar less leaky to harmful ions because of its finer particle size distribution and pozzolanic reactions. This ends up in an increased high performance and additional sturdy mortar. Variety of studies of the results of the fly ashes on the behavior of cement pastes, mortars, and concretes were additionally distributed. Paper has examined the impact of ash used as replacement addition to the Ordinary Portland cement (OPC) on the compressive strength development of cement mortars of Khaperkheda thermal station. the mix proportion 1:3 of cement mortar within which cement is part replace with ash as 0%, 5%, 10%, 15% and 20% by the burden of cement. Compressive strengths of the mortar specimens were determined at seven and twenty eight days. Results show that strength will increase with the rise of ash up to an optimum value, beyond which, strength values begin decreasing with more addition of ash.
