| Abstract: | Through the method of accelerated freeze-thaw,the freeze-thaw durability of three kinds of concretes subjected to water and 5%(by mass) MgSO_4 solution was studied.The concretes studied include high strength concrete(HSC),high-volume mineral admixture concrete(HVMAC) and high durable concrete (HDC) with high-volume mineral admixture,air-entraining agent,superplasticizer,fibers and expansion agent added.Results show that for higher water binder ratio,lower content of mineral admixture of HSC,MgSO_4 solution ... |
