摘要
在轻骨料混凝土中掺入不同量的聚丙烯纤维,对混凝土的抗压强度,轴心抗压强度,弹性模量,抗折强度及弯曲韧性进行研究,比较了聚丙烯纤维轻骨料混凝土的力学性能与强度等级的关系,结果表明:掺入聚丙烯纤维可以有效的改善混凝土的抗折强度和弯曲韧性,而抗压强度与强度等级有关。
Through incorporating different percentage of polypropylence fiber in a lightweight aggregate concrete,the compressive strength,axial compressive strength,modulus of elasticity,flexural strength and bending toughness of the concrete are resereched.At the same time,the releationship between mechanical properties and intensity scale is also compared.Results showed that polypropylence fiber can improve the flexural strength and bending toughness,but the compressive strength is related with the intendity scale.
