摘要
高温条件下大体积砼工程温控施工的核心是降低砼的入模温度减少砼的绝热温升,以达到控制砼浇注块体温度裂缝的目的。文章从原材料的选择、配合比的确定、砼制作温度的控制、现场施工等方面论述了核电工程大体积砼施工所采取的砼拌合物温控措施,为以后的类似工程的施工提供参考。
The key point of the bulk mass concrete construction's temperature controlling under high - temper condition is to reduce the temperature of the concrete sent into the mold and reduce the adiabatic temperature rising, for controlling the temperature crack of concrete blocks. This paper discussed the measure of temperature controlling of nuclear power bulk mass concrete construction through several parts, such as: the raw materials choosing, the material match compared settling, the concrete temperature controlling and spot constructing etc.. It provides a reference to the similar construction.
