黄麻纤维增强混凝土的抗压和抗折性能研究

摘要

在混凝土中添加黄麻纤维，以增强混凝土的抗压和抗折性能。通过测定纤维增强混凝土的抗压和抗折强度，并与素混凝土进行对比，进而研究黄麻纤维的长度和掺量对混凝土的增强作用。结果表明：黄麻纤维长度为30 mm，掺量为0．5～0．6 kg/m 3时，对混凝土的抗压及抗折强度增强作用最为显著。%Jute fibers were added into concrete to improve its compressive and flexural strength.In comparison with the pure concrete, the enhancement of jute fiber’s length and mixing amount in concrete was stud-ied by testing the compressive and flexural strength of fiber reinforced concrete.Test results showed that the compressive and flexural strength of the fiber reinforced concrete were significantly enhanced with 30 mm length jute fiber at the mixing amount of 0.5~0.6 kg/m 3 .
