指出当前综合蓄热法施工中确定混凝土防冻剂掺量的不尽合理之处，经试验研究提出了以混凝土热工计算公式和成熟度公式为基础，结合不同掺量防冻剂混凝土的不同冰点，提出负温混凝土防冻剂掺量的新方法。并通过试验进行了验证，得出该方法方便可行。

The unreasonable aspects for ascertaining the amount of concrete anti-freezing agent used in the present comprehensive thermal storage method is pointed out. A new method for determining the amount of anti-freezing agent used in the negative temperature concrete was proposed through tests, based on the thermal calculating formula, maturity formula and the freezing points of different kinds of concrete with different amount of anti-freezing agent. The new method was proved to be convenient and feasible by tests.
