EXPERIMENTAL RESEARCH ON THE MECHANICAL BEHAVIOR OF CHOPPED BASALT FIBER REINFORCED CONCRETE
-
摘要: 对玄武岩纤维的研究已成为目前国内外研究的热点。在混凝土中掺加乱向短切玄武岩纤维后,其强度及抗裂性能均会得到改善。完成了涉及6种长径比和5种体积掺量的194个试件的试验,对短切玄武岩纤维体积掺量、长径比等因素对混凝土抗压、劈拉、弯拉强度的影响进行研究,积累了大量的数据,为进一步研究奠定了基础、积累了经验。Abstract: More attention is focused on experimental research on basalt fiber in home and abroad.Strength and crack resistance capability of concrete will be improved after being reinforced by chopped basalt continuous fiber.A hundred and ninety-four test pieces are tested which involved six kinds of slenderness ratios and five cubic contents,and studies are done on the influence of cubic content and slenderness ratio to compressive strength,split strength and flexural strength of concrete,which lays the foundation of further study.
