Abstract
It is requested evaluation method for frost resistance of exterior materials in cold region considering natural conditions. In our laboratory, it was shown the possibility of evaluation for the frost resistance based on the water absorption properties, however it is not clear relation the frost resistance and the water absorption properties of materials exposed to alternative immersion. In this paper, it is investigated the water absorption properties of mortar considering the effects of W/C, Air, alternative immersion and so on, and also investigated these of the properties on the frost resistance. The results show high correlation between the speed of initial water absorption and the mass change due to frost damages is observed.
