In this study, concrete and reinforced concrete have been produced by using fly ash (FA) at 0%, 15%, 30% and 45% ratios replace by CEM I 42.5 R cement which is used as 300 doses. The specimens produced have been kept in two different cure durations which are for 28 and 56 days and in two different conditions which are air and water. Physical, mechanical, and durability properties of the produced specimens of concrete and reinforced concrete have been determined. Unit weight, ultrasonic pulse velocity, dynamic elasticity module, Schmidt hardness, splitting-tensile, compressive, and chloride ion permeability tests have been done on concrete specimens. On reinforced concrete specimens, accelerated corrosion tests have been done. As a result of the tests, it was concluded that it is very important that water cure is done for 56 days and also that quite durable concretes against corrosion can be produced by using FA at 15% ratios replace by cement.
