摘　　要：通过分析工程实例,针对当地水泥水化热过高、骨料级配不合理等情况,简单介绍火力发电厂汽机底板大体积混凝土配合比的研究,探索降低混凝土水化热的有效途径,确保大体积混凝土结构无温度裂缝出现。In this paper, the paper puts forward the effective way to reduce the hydration heat of concrete by simply studying the mixing ratio of mass concrete in the turbine floor of the thermal power plant, and so on, according to the example of the local cement hydration heat is too high and the aggregate gradation is unreasonable. To ensure that there is no temperature cracks in the mass concrete structure.

关 键 词：大体积混凝土 温度裂缝 水化热 双掺技术
