This paper presents the results of series of experimental studies on effects of the type and replacement ratio of fly ash to Portland cement on concrete properties. Type I and type II fly ashes indicated higher water reduction with the increase of replacement ratio up to 70%. Reduction in 28 day compressive strength was smaller for type I fly ash than for type II and type IV fly ashes. Drying shringkage decreased with fly ash addition regardless of type and replacement ratio of fly ash. Carbonation increased with fly ash replacement ratio, and type I fly ash showed higher carbonation. Type I and tpye II fly ashes showed practically no change in durability factor after 300 cycles of freezing and thawing up to 55% replacement, while type IV fly ash showed rapid reduction in durability factor regardless of fly ash replacement ratio.
