摘　　要：自密实混凝土作为一种新型的高性能的混凝土材料,其应用范围较广泛,在水利枢纽建设中应用也越来越广,可以解决大体积混凝土(如重力坝)复杂的温控而产生的裂缝问题,同时也简化了温控措施,较常规混凝土、碾压混凝土坝体相比提高了大坝的安全稳定性,简化了施工工艺。自密实混凝具有高流动性的特性,可以缩短施工工期和保证施工质量,通过材料的合理利用可以降低施工能耗,减少粉尘和废弃物的排放,减少工程对周围环境的影响,通过提高堆石率可以降低施工成本,从而达到节约工程投资,降低工程造价,其工程效益较为显著。Self-compacting concrete as a new type of high performance concrete material,its application scope is broad,is becoming more and more widely used in water conservancy construction,mass concrete can be solved,such as gravity dam complex temperature control and crack problems,and also simplify the temperature control measures,are increased compared to conventional concrete.Due to RCC dam safety stability of the dam,the construction process is simplified.The characteristics of self-compacting concrete with high fluidity,can shorten the construction period and ensure the construction quality,through the reasonable use can reduce the energy consumption of construction materials,reduce dust and waste emissions,reduce the influence of engineering on the surrounding environment,by improving the heap of stones rate can reduce the construction cost,so as to save construction investment,reduce the project cost,the engineering benefit is significant.
