大体积混凝土由于水泥水化热产生的温度应力,易出现混凝土温度裂缝。为了防止和避免这种裂缝的产生,在混凝土原材料的选择和配合比的确定两方面进行控制,以保证大体积混凝土工程的施工质量。
Massive concrete due to the heat stress of cement hydration heat, prone to concrete temperature cracks. In order to prevent and avoid the occurrence of such cracks, control is performed in the selection of concrete raw materials and the determination of the mix ratio to ensure the construction quality of the mass concrete works.
