《建筑技术》1979年第10期刊载的《混凝土在负温度下的硬化及临界温度》一文,对冬施提供了一些很有用的资料,并对混凝士冬施的基本理论有较好的阐述。但该文仍然存在一定问题,现提出与项玉璞同志商榷,并就教于有关同志。关于混凝土含冰量对后期强度的影响问题。根据该文所提数据,看来混凝土的冻结只能使水泥的水化反应减缓或暂时停止;恢复正温以后,水泥的水化作用仍能继续进行。也就是说,冻结对水泥的最终水化作用 The paper “The Hardening and Critical Temperature of Concrete at Negative Temperatures” published in the 10th issue of “Architecture Technology,” 1979, provides some useful information for winter applications, and it has a better understanding of the basic theories of using concrete for winter. Explained. However, there are still certain problems in the article. We now propose to discuss with Comrade Xiang Yuxi and teach it to the relevant comrades. Questions about the effect of concrete ice content on later strength. According to the data provided in the article, it appears that the freezing of concrete can only slow down or temporarily stop the hydration reaction of cement; after the restoration of positive temperature, the hydration of cement can continue. In other words, the final hydration of the cement
