Abstract: It is the first vast application of low-heat cement in the concrete used for construction of a 300 m super-high double curvature arch dam. Through the research and application of low-heat cement and low-heat cement concrete, the performance characteristics of concrete in the construction process have been comprehensively mastered. By giving full play to the characteristics of low-heat cement such as low hydration heat, high strength and good durability, the overall quality of concrete construction of Baihetan hydropower station has been effectively guaranteed.

Key words: Baihetan hydropower station, low-heat cement, mix proportion, temperature control

摘要： 低热水泥在大坝主体混凝土中的全面应用，特别是在 300 m级特高双曲拱坝混凝土中的应用尚属首次[1]。通过对低热水泥和低热水泥混凝土的研究应用，较全面地掌握了混凝土在施工过程中的性能特点，充分发挥低热水泥低水化热、后期强度高和耐久性好等特点，有效保障了白鹤滩水电站大坝混凝土施工的整体质量。
