介绍了大体积混凝土的主要特点与种类,从水泥水化热内外约束条件、外界气温变化、混凝土收缩变形等方面,分析了大体积混凝土产生裂缝的原因,并提出了主要的防治措施,从而保证大体积混凝土的工程质量。
The main characteristics and types of mass concrete are introduced. The causes of cracks in mass concrete are analyzed from the aspects of internal and external constraints of hydration heat, the change of ambient air temperature and the shrinkage of concrete, and the main control measures are put forward so as to ensure Mass concrete engineering quality.
