混凝土是一种人造石材,其所以具有强度主要是水泥熟料矿物成分和水的水解和水化反应而形成水泥石的结果。这种水解和水化反应需要一定的温度湿度。因此要使混凝土在短期内获得必要的强度,就要有一个相应的温度、湿度条件,水泥的凝结硬化时的温度越高,这种反应越剧烈,温度越低,越缓慢,当温度降低到负温时这种反应趋于停止状态。
Concrete is a kind of man-made stone, so its strength is mainly the result of hydrolysis and hydration reaction of cement clinker mineral components and water to form cement stone. This hydrolysis and hydration reaction requires a certain temperature and humidity. Therefore, in order to obtain the necessary strength for concrete in a short period of time, there must be a corresponding temperature and humidity conditions. The higher the temperature of the setting and hardening of cement, the more intense this reaction is, the lower the temperature, the slower, when the temperature is reduced to This reaction tends to stop at negative temperatures.
