本文对硬化混凝土气泡间距系数的临界值进行了讨论分析，建议港工混凝土施工规范中增补规定，对于有抗冻要求混凝土的气泡间距系数，其临界值取0．230mm，这对评估硬化混凝土抗冻性有着重要实际意义。

This paper analyzed and discussed the critical values of the air bubble spacing coefficients of hardened con-crete- It is recornmended that the critical value 0. 23mm of the air bubble spacing coefficients for the concrete re-quiring resistance to freeze should be added in the Specifications for Concrete Construction of Port Engineering.It will have a practical and important significance in evaluating the forst resistance of the hardened concrete.
