Abstract: In this research, it is supposed that water permeable concrete is being used in several environments. For example, it is being used on the ground, near lakes or in river. In these humid conditions, the permeable concrete will reach a degree of saturation. In the winter, concrete is subjected to freeze-thaw attack, damage to the internal structure of the con¬crete as well as to its surface can occur. The degradation is enhanced if a de-icing agent attacks at the same time. Therefore it is necessary for us to discuss about the resistance against freeze-thaw attack. In general, when the permeable concrete is set up on the per¬meable back-filling material, water is not retained in the continuous-void, but retained in the void of matrix due to capillary suction. This action is an important reason that the freeze-thaw attack occurs. The correlation between the water permeability and the resis¬tance of permeable concrete against freeze-thaw attack will be mainly discussed in this paper. RILEM TC-117 CIF/CDF is adopted as the testing method for the resistant against freeze-thaw. The water permeability of the test specimens is varied from 2 to 0.1cm/s in the range of normal permeable concrete.
