Influence of particle size distribution of fly ash on compressive strength and durability of Portland cement concrete
The present research investigates the compressive and durable properties of concretes with fly ash (FA), a by-product of Coal-fired Power Plants. For this purpose, a reference sample and twenty-one concretes containing FA were tested. The FA was sieved to 200, 300, and 400 mesh. Then FA was mixed into concrete with different content. Compressive strength at 7 and 28 days, and chloride penetration properties were measured. It is concluded that FA can be used in the production of concrete. In addition, the FA concretes present satisfactory physical properties. When proper amount of FA were added the concrete properties can be better than the blank one.
