摘要
本文探讨了聚丙烯纤维增强砂浆的机理,对不同聚丙稀纤维掺量下砂浆的抗折抗压、弹性模量和收缩变形进行研究,分析了纤维的加入对普通水泥砂浆的影响。试验结果表明纤维的加入能提高砂浆的抗折强度,降低砂浆的弹性模量和收缩率。
The paper studies bending resistance,elastic modulus,and systolic deformation of cement mortar in different polypropylene fiber volume fraction,and analyzes the influence on the cement mortar.The test manifests adding a certain content of fiber in the mortar can obviously improve the flexural strength,decreasing the elastic modulus and shrinkage.
