摘要
在冬季混凝土施工中,水泥的水化热是一项可以利用的能源。本文以实际试验为基础,经分析后提出了水化热的预测方法。这个方法是:当水泥中的矿物成分含量以及混凝土的硬化温度与养护时间为已知时,可采用数学方法计算出混凝土中水泥的累计放热量,这一方法可在工程中应用。
During concrete winter construction, the hydration heat of cement can be made use of as a sort of energy. In this article, based upon practical experimentation and analysis, it has introduced the method of prediction for the hydration heat in concrete. This method has been based upon and included in the following crucial items namely:the content of mineral ingredients in cement, the amount of cement used, and the hardening temperature of concete as well as the time length of concrete curing period. The accumulative hy- dration heat of cement in concrete can be obtained by the mathematical calculation method and it is widely adopted in building costruetion.
