自密实混凝土(简称SCC)与普通混凝土在建筑中有着很广泛的应用,这两种混凝土在不同的建筑领域有着自身的优点。本文研究SCC与普通混凝土在同样的原材料和矿物掺合料下,SCC的坍落扩展度比普通混凝土大,SCC的流动性、抗离析性和填充性比普通混凝土的更具有优异性,同样原材料、矿物掺合料和不同的配合比下,SCC比普通混凝土的干缩系数大。 Self-compacting concrete (referred to as SCC) and ordinary concrete in the building has a very wide range of applications, these two kinds of concrete in different areas of the building has its own advantages. In this paper, SCC and ordinary concrete in the same raw materials and mineral admixture, SCC slump expansion than ordinary concrete, SCC fluidity, anti-segregation and filling than ordinary concrete more excellent, the same raw materials , Mineral admixtures and different mixture ratio, SCC than normal concrete shrinkage coefficient.
