摘要
水泥的水化反应除生成一系列水化产物外,还会产生大量的水化热,因此,在进行大体积混凝土施工时,混凝土结构往往会因为内部温升过高而出现温度裂缝,不利于工程质量的控制。文章结合了客运专线某特大桥C50桥墩温度控制施工的实践,对大体积混凝土内部温度的变化规律进行监测,同时对相应的温度控制措施进行探讨。
The hydration of cement will give out a lot of hydration heat. Therefore, in the massive concrete construction, the internal excessive temperature rise will produce temperature cracks, which are not conducive to the project quality. During the construction of some extra-large bridge, temperature changes inside concrete were timely detected through real-time monitoring. The observational data and corresponding temperature control measures were discussed.
