This paper studies the effect of curing temperature on the early freezing-thawing resistance of HVFA concrete, and determines the early freezing-thawing resistance of HVFA concrete under different curing temperatures by testing the compressive strength, mass and ultrasonic wave velocity of the specimens. The results show that curing temperature has a certain influence on the early freezing-thawing resistance of HVFA concrete. The decrease rate of the compressive strength of HVFA concrete cured at 40℃ is the least, and the quality of HVFA concrete cured at different curing temperatures firstly increases and then decreases with the increase of the number of freezing-thawing cycles. According to the freeze-thaw damage value defined by wave velocity, curing temperature has a great influence on the freeze-thaw damage of HVFA concrete.
