摘　　要：研究了废纸纤维、UF500纤维素纤维和聚丙烯纤维对水泥浆体抗折强度和抗压强度的影响。通过氮吸附法对水泥浆体的孔结构进行了测试,分析了三种纤维掺入后对水泥浆体孔结构的改变。试验结果表明:密封养护条件下,三种纤维对水泥浆体强度和孔结构的影响是不同的,废纸纤维对水泥浆体强度和优化孔结构方面的影响略次于UF500纤维素纤维,但优于聚丙烯纤维,从成本方面考虑,用废纸纤维代替UF500纤维素纤维是值得尝试的。The effects of various fibers, such as waste paper fibers, UF500 cellulose fibers and polypropylene fibers, on the flexural strength and compressive strength of cement paste were studied in this paper. The pore structure of cement paste mixed with various fibers was determined and analyzed by a nitrogen adsorption method. The result showed that under the sealed curing, the impact of three kinds of fibers on the strength and pore structure of cement paste were different, in which waste paper fibers was slightly than UF500 cellulose fibers, but was superior to polypropylene fibers. If considering the cost, this practice that waste paper fibers instead of UF500 cellulose fibers was worth taking
