摘要
对正在进修修订并准备１９９６年实施的中华人民共和国建材行业标准《混凝土防冻剂》（ＪＣ４７５）要增加的条文──负温下防冻剂混凝土强度增长指标进行了研讨，并指出了该条文增加的必要性。并讨论了新修订的规范在负温混凝土工程实践中的实用性。
It was discussed that to need adding a article, to dovelopment rate of strength which is concretewith antifreezing admixtures in the special criterion of PRC - Concrete antifreezing admixtures(JC475). This criterion is revising by a lot of investigator and it should used to practice engineering in1996. Research shown: adding this article is necessary in the JC475.
