Abstract :Fly ash is the waste product of the thermal power plants, where coal is burned for generating electricity. Using fly ash in concrete production is one of the important ways of reducing its negative effects. When fly ash is used alone, it doesn’t show binder property. However, if it is added to concrete mixture with cement, it improves the mechanical and durability properties of concrete.In this study, F and C type fly ashes efficiencies and their effects on the mechanical properties and durability of concrete are compared. For this study, 39 different mixtures were produced. Çatalağzı Thermal Plant fly ash insert ignore into journalissuearticles values(F type);, Çayırhan Thermal Plant fly ash insert ignore into journalissuearticles values(C Type); and CEM I 42,5 R type cement were used as binder. When exposed to magnesium sulphate, control specimens showed higher deteriorations when compared with concretes with fly ash. This also confirmed that fly ash improved the durability properties.
Keywords : Fly ash, mechanical properties, strength, flexural strength, sulphate resistance
