Experimental Research on Sulfate Attack Resistance of Steel Fiber Reinforced Fly Ash Concrete

Abstract:

Sulfate attack is one of the important factors affecting the durability of concrete. An experimental work had been carried out to investigate the behavior of steel fiber reinforced fly ash concrete (SFRFAC) exposed to sulfate attack in comparison with the plain concrete (PC), fly ash concrete (FAC) and steel fiber reinforced concrete (SFRC).The sulfate resistance of the SFRFAC, PC, FAC and SFRC under sodium sulfate attack of different concentrations were evaluated by measuring the compressive strength and flexural strength. The results show that the sulfate resistance of SFRFAC is higher than those of PC, FAC, and SFRC. With the increase of sodium solution concentration, the compressive strength and flexural strength of SFRFAC, PC, FAC and SFRC decrease first, and then increase.
