摘要(Abstract):
通过改变同种材质粗骨料的最大粒径,并在同一添加量下改变玄武岩纤维长度,对骨料最大粒径和纤维长度对混凝土强度的影响进行了研究。试验结果表明:不同骨料最大粒径的混凝土添加玄武岩纤维后,抗压强度增加幅度没有抗折强度增加的幅度大;同比情况下,玄武岩纤维长度为18 mm的增强效果较好,骨料最大粒径没有对混凝土强度产生太大影响。
By changing the maximum particle size of coarse aggregates of the same material, and changing the basalt fiber length at the same addition amount, the study on the influence of the maximum particle size of the aggregate and the fiber length on the strength of concrete is completed. The test results show that the increase in compressive strength is not as large as the increase in flexural strength after adding basalt fiber to concretes with different maximum aggregate particle sizes; compared with the same period, the basalt fiber length of 18 mm has a better reinforcement effect, and the aggregate particle size does not have much influence on the strength of concrete.
