In this study, deterioration degrees of concrete was investigated at a lab under cycling freeze-thaw, which is major durability performance deterioration factors of concrete. After 300 cycles of freeze-thaw, relative dynamic modulus of elasticity and compressive strength of concrete mixed with normal Portland, SF, and Ny over 90 to 93% showed relatively low resistance of approximately 78 to 87% of those values of FA-PP-02. The SF-01 specimen showed the most excellent freeze-thaw resistance among the tested high performance concrete.
