摘要
分析了冬期施工中存在的几种不同抗冻临界强度的概念，指出了空白砼的抗冻临界强度与防冻剂砼抗冻临界强度之间的本质区别，并提出了广义抗冻临界强度的概念，为负温砼工程实践提供了理论基础。
There are some different concepts of frost-resisting criticals strength in winter construction. These coneadepts were analysed in the paper. Our analyse theirs nature differnce,especial between plain concrete and anti-freezing admixture concrete in frost-resisting critical strength. and then our put fowards to a concept ofgeneralized frost-resisting critical strength. It may was considered theoretical basis for minus --temperatureconcrete engineering construction.
