| 摘 要： | 自密实混凝土(SCC)具有降低能耗、改善环境、提高效率、增加密实性等优点,作为绿色环保建筑材料已在国内外得到广泛应用。为了获得更好的施工性能和填充性能,在混凝土中掺加了大量的矿物掺合料,随着各种各样的矿物掺合料的掺加,自密实混凝土也面临着收缩问题,出现了早期裂缝,严重影响了混凝土的使用寿命。基于目前的研究现状,本文研究了矿物掺合料对自密实收缩性能的影响。

| Abstract: | self compacting concrete(SCC)has the advantages of reducing energy consumption,improving the environment,improvingefficiency,increasing compactness and so on.It has been widely used as green building materials at home and abroad.In order to obtain better construction performance and filling performance,a large number ofmineral admixtures are involved in the concrete.With the addition of variousmineral admixtures,self compacting concrete is also facing the problem of shrinkage.Early cracks appear,which seriously affect the service life of concrete.Based on the current research situation,this paper studies the influence ofmineral admixture on the self compacting shrinkage performance. |
