本文综述了关于大坝混凝土的经验.在重力坝中,混礙土的强度实际上一般决定于实际可能的最低水泥用量,而不是决定于设计应力.混凝土的耐久性得到了普遍重视.近来有不少工程采用了粉煤灰作为混合材料。随着施工设备的改进,有些国家采用了低流态混凝土浇筑混凝土坝.为提高混凝土坝的质量,加强了溫度控制和质量控制. This article summarizes the experience of dam concrete. In gravity dams, the strength of mixed soils is actually determined by the actual lowest possible amount of cement, rather than by the design stress. The durability of concrete has been given universal attention. Many projects use fly ash as a mixed material. With the improvement of construction equipment, some countries have adopted low-flow concrete pouring concrete dams. In order to improve the quality of concrete dams, temperature control and quality control have been strengthened.
