Abstract

Fly ash is an expensive replacement of Ordinary Portland cement (OPC) used in concrete, while it improves fresh and hardened properties of the concrete. Fly ash, a byproduct from coal burning in thermal power stations is currently disposed of in landfills. It is essential that the utilization of fly ash in useful applications should increase dramatically to reduce the use of land for waste disposal. This paper presents the experimental investigation on the mechanical properties of high volume fly ash concrete. Portland cement was replaced with 50% fly ash. Compressive strength and flexural strength of fly ash concrete were experimentally found out and compared with ordinary concrete. Two different superplasticisers were used to cast the specimens. The investigation revealed that the compressive strength and flexural strength of fly ash concrete specimens are comparable to that of ordinary concrete specimens.
