玄武岩纤维掺量对页岩陶粒混凝土性能的影响
|
摘要
为研究玄武岩纤维掺量对轻质陶粒混凝土性能的影响,制备了4种不同纤维掺量的陶粒混凝土试件,测试了不同龄期试件的抗压强度、抗折强度和表观密度。结果表明:陶粒混凝土立方体试件抗压强度随着玄武岩纤维掺量的增大先增加后降低;陶粒混凝土表观密度随着纤维掺量的增大而逐渐降低,但不显著;陶粒混凝试件抗折强度随纤维掺量增大不断提高。
In order to study the effect of basalt fiber dosage on the properties of lightweight aggregate concrete, four kinds of ceramsite concrete with different fiber content of the specimen were prepared. The compressive strength, the flexural strength and the apparent density of specimens at different ages were tested. The results show that the compressive strength of ceramsite concrete cube specimen increases first and then decreases with the increase of the basalt fiber content, the apparent density decreases with the increase of fiber content of ceramsite concrete, but not significantly, and the flexural strength of ceramsite concrete increases with the increase of fiber content.
