Abstract
Concrete is a composite material composed of both coarse and fine aggregates. River sand is considered as one of the most used fine aggregate in the world, but with the expansion of the Construction scale of our country, the shortage of river sand resources is becoming more prominent. Fly ash (FA) from the thermal plants is available in large quantities in fine and coarse form. Fine fly ash is used in construction industry in some amount and coarse fly ash is subsequently disposed over land in slurry forms. The fly ash can be used to overcome the shortage of river sand and avoid excessive sand mining which can bring ecological environment problems, because of the presence of chloride ions in the fly ash the steel in the concrete may be corroded and hence care should be ensured while using fly ash as a fine aggregate. The salt in the fly ash should be treated before used for construction to avoid disaster. In this paper the investigation is made on the developed concrete by adding fly ash as a fine aggregate. The river sand (fine aggregate) is replaced by fly ash in terms of 100% and 50%. Another test is carried out with replacing river sand with fly ash along with GGBS as coarse aggregate and then several tests were carried out to check its durability. The test results show that it is more significant to use fly ash as an aggregate to the concrete by partially replacing it with river sand.

Key-Words / Index Term
