聚丙烯纤维对沙漠砂自密实混凝土性能影响的研究
Study on Effect of Polypropylene Fiber on Properties of Desert Sand Self-Compacting Concrete
摘要
Abstract
The influence of water-glue ratio,fly ash content,desert sand substitution rate and polypropylene fiber content on the 28 d flexural strength of desert sand self-compacting concrete was studied through orthogonal test.The results show that the effects of preparation conditions on the flexural strength of concrete at 28 d are in the order of desert sand substitution rate>water-glue ratio>polypropylene fiber content>fly ash content,and the optimal parameter combination is A1B3C3D3.Compared with ASC-0,the cracking inhibition rate of the ASC-3 group is as high as 54%,and the dry shrinkage rate is reduced by 18.3%.Therefore,polypropylene fiber can improve the mechanical properties,crack resistance and shrinkage resistance of desert sand concrete.关键词
