摘　　要：混凝土材料是建筑物中用量最大的材料之一,近年来,由于我国国民经济的飞速发展,对混凝土材料及其施工技术也提出了越来越高的要求。自密实是一种高性能混凝土,是具有超高的流动性和抗离析性能的混凝土,靠着自留填充作用不需要任何振捣成型措施,能通过浆体跟碎石圆润性,可以自动充满整个模腔,并具有匀质性和体积稳定性。Concrete material is one of the most widely used materials in buildings.In recent years,due to the rapid development of our national economy,higher and higher requirements have been put forward for concrete material and its construction technology.Self compacting is a kind of high-performance concrete,which has ultrahigh fluidity and anti segregation performance.Under the action of self weight,it does not need any compacting and forming measures.It can pass through the dense area of reinforcement without leaving any holes,automatically fill the entire mold cavity,and has homogeneity and volume stability.
