摘要	The antifreeze critical strength and the pre-curing time of low-temperature concrete were studied by means of guaranteed rate of compressive strength and antifreeze performance for the structural safety requirement of concrete engineering, suffering once freeze damage under air environment. It is shown that the antifreeze critical strength is 3.7-4.4 MPa, pre-curing time is 18-32 h by guaranteed rate of compressive strength, and the antifreeze critical strength is 3.7-4.4 MPa, pre-curing time is 18-32 h by guaranteed rate of antifreeze performance. It can be found that the Method of guaranteed rate of compressive strength is sensitive to the defect which generated by freeze damage in the concrete interior. The method is fit to evaluate the antifreeze critical strength of low-temperature concrete.
