摘　　要：采用聚丙烯纤维和聚合物乳液对水泥砂浆进行改性,并对改性水泥砂浆抗冲击性能和干燥收缩性能进行了实验研究.研究表明,聚丙烯纤维和聚合物乳液对水泥砂浆的抗冲击性能和干燥收缩性能具有一定影响,合掺聚丙烯纤维和聚合物乳液可显著改善水泥砂浆的抗冲击性能和干燥收缩性能.另外,探讨了聚丙烯纤维和聚合物乳液改善水泥砂浆抗冲击性能和干燥收缩性能的作用机理.Adopt polypropylene fibers and polymer emulsion to improve the shock resistance and drying shrinkage performance of cement mortar. The result shows that mixing polypropylene fibers or polymer emulsion separately can slightly improve the shock resistance and drying shrink- age performance and mixing polypropylene fibers and polymer emulsion at the meantime can improve the shock resistance and drying shrinkage performance more effectively. The interaction between inorganic and organic phases has been discussed.
