【摘要】 对钢纤维和聚丙烯纤维混杂的砂浆混凝土的弯曲性能进行了分析,探讨这种钢纤维和聚丙烯纤维混杂增强复合材料是否有较高的初裂强度和较高的韧性,试验结果表明,混杂纤维增强砂浆混凝土的弯曲性能比单一纤维增强砂浆混凝土的弯曲性能明显地得到改善,这种混杂纤维增强砂浆混凝土的复合材料性能很好地发挥出了钢纤维和聚丙烯纤维各自增强砂浆混凝土的优点。更多还原

【Abstract】 This paper analyzes bend characteristics of hybrid mortar concrete of steel fiber and polypropylene fiber,and discusses whether hybrid reinforced composite material of steel fiber and polypropylene has higher incipient crack strength and toughness.Experimental results show that: bend characteristic of hybrid fiber reinforced mortar concrete is more improved than that of single hybrid fiber reinforced mortar concrete.The composite material of hybrid fiber reinforced mortar concrete can better play the role of steel fiber and polypropylene fiber in reinforcing mortar concrete.更多还原
