abstract="The frost resistances of three kinds of concretes under flexural stress subjected to water and 5% MgSO4(mass fraction) solution were studied by using accelerated freezing-thawing method. The considered concretes include high strength concrete(HSC) added with 20% fly ash (20% of binder mass), high-volume mineral admixture concrete(HVMAC) added with 40% fly ash, 10% slag and 5% silica fume, and high durable concrete(HDC) added with high-volume mineral admixture, air-entraining agent, superplasticizer, fibres and expansion agent. Third point loading method was applied on the specimens in the process of freezing-thawing cycle, and the enacted flexural stress was 35% of failure stress. Analysis result shows that the frost resistances of HSC and HDC respectively increase 46 times and more than 70% under flexural stress subjected to MgSO4 solution as compared with water, and their anti-freezing-thawing cycles are respectively more than 425 times and 900 times. But the frost resistance of HVMAC decreases by 67% under flexural stress, and its anti-freezing-thawing cycles are only 75 times.<p />",
