英文摘要	The use of deicing salt in the winter of northern China can seriously affect the durability of concrete for bridge deck overlays. In order to solve this problem, the law of freezing-thawing damage development under different situation has been studied. Rapid hardening sulphoaluminate cement(SAC), polymer-modified fast-hardening cement(JS) and ordinary Portland cement(P. O) were placed in NaCl solution with mass concentration of 0% and 3.5% to conduct fast freeze-thaw cycles experiment. Besides, with the help of SEM, the internal damage mechanism of different kinds of concrete under water and salt freezing environment were analyzed. Results showed that compared with the concrete in salt freezing situation, the sample in water freezing situation did not show apparent mass loss, which meant that the freezing-thawing damage rate was slow and the damage was in a low degree. The antifreeze characteristic sequence of concrete both in two situations is P. O>JS>SAC. In salt freezing situation, more Fridel salt was yielded as corrosion products, which aggravated the collapsing of concrete. © 2017, Materials Review Magazine. All right reserved.
