摘要
选用不同尺度的钢纤维、高弹维纶纤维、低弹聚丙烯纤维 ,按二元或三元混杂增强水泥基复合材料 ,系统研究了其限缩与抗渗性能及其与膨胀剂的复合效应 ,并通过孔结构测试剖析了纤维混杂增强及其与膨胀剂复合对提高水泥基的限缩与抗渗能力的机理 .
In this paper, hybrid fibers including steel fibers, high elastic modulus polyvinyl alcohol fibers and low elastic modulus polypropylene fibers of different sizes hybridized as two elements or three elements are used to be reinforcement in cementitious matrix. The properties of shrinkage resistance and permeation resistance of hybrid fibers, as well as the combined effects of hybrid fibers and expansive agent are investigated systematically. The mechanism of the effect of hybrid fibers, as well as the combined effects of hybrid fibers and expansive agent on the above two properties is analyzed by the measurement of pore structure.
