As the industrialization is rapidly growing, the quantities of industrial waste glass have been quickly increased. However the most of them are not recycled. Therefore, it is needed to investigate the possibility of industrial waste glass as concrete material ingredient. In this paper, it is compared and evaluated that the characteristics of freeze-thaw resistance according to industrial waste glass substitution ratio in concrete specimens. From the results, the weight change was not affected by the waste glass substitution ratio. And, the relative dynamic modulus of elasticity was increased slightly with the waste glass substitution ratio. The relative dynamic modulus of elasticity was above 80% up to 300cycles in all of the mixes.
