High Strength Concrete Using Fly A Cement And Fine AGGREGATE

At the moment, the cost of concrete is quickly increasing as the cost of cement and aggregatescontinues to rise. As a result, a replacement for fine aggregate as well as a substitute for cementis required to decrease the cost of concrete production. In general, concrete is composed of
cement as a base material that is workable and satisfies specified performance, durability, andstrength criteria, aggregate, and water. In the field of engineering constructions, reinforced highstrength concrete has a significant impact on development. Apart from its exceptional strength,
this kind of concrete must exhibit workability, minimal shrinkage, releasing characteristics, and

self-compaction. The authors of this research performed a literature review to explore high-
quality concrete made using fly ash as a replacement for cement and fine particles. Fly Ash is awaste product or byproduct of the coal-fired power plant's combustion process. Fresh concretemade using fly ash as cement and fine aggregate has an average slump value of 90-200 mm. Thecompressive strength of concrete made with fly ash ranges between 35 and 60 MPa after a 28-day curing period. The optimal percentage of fly ash in high strength concrete is between 10%and 30%.
