Abstract: The effect of temperature on the setting time,compressive strength and durability of high strength concrete were studied.The results show that: when the temperature between 10-15 ℃,with the increase of temperature setting time decreases most quickly;when the temperature is between 20-30 ℃,with the increase of temperature setting time does not change the basic.When the curing temperature is at 10-20 ℃,high performance jet erosion ability of sulphate resistance of concrete.When the temperature is at 20-30 ℃,high performance jet concrete chloride ion diffusion coefficient is very low.When the curing temperature is at 5-15 ℃,more favorable to the frost resistance of high performance concrete.
