In order to prevent freezing trouble during winter, cold regions have been spread deicing salts and thess type of deicing salts usually consists of alkaline such as sodium chloride, calcium chloride. The types of deicer have different propertis which also can lead various deterioration of concrete load structure. In this study, to evaluate structure degradation according to different types of deicing salts, compressive strength and relative dynamic modulus of elasticity (RDME) are used on salt contaminated concrete.??? ????????? 2015?????? ??????(?????????????????????)??? ???????????? ????????????????????? ????????? ?????? ????????? ?????? ???????????????(No. 2015R1A5A1037548
