奥米矿物纤维在混凝土中的应用性能研究

Naomi Mineral Fibers in the Performance of Concrete

通过大量试验,对比研究了普通硅酸盐混凝土、聚丙烯纤维混凝土及奥米矿物纤维混凝土的力学性能、长期性能和耐久性能,以及微观结构特征。分析表明,奥米矿物纤维能显著改善混凝土的抗冲击性能和抗裂性能;相比聚丙烯纤维,与混凝土具有更好的相容性;可应用于路面、桥面、屋面等抗冲击、抗疲劳、抗裂性等要求较高的工程。

By a large number of experimental, comparative study of ordinary Portland concrete, polypropylene fiber reinforced concrete and Naomi mineral fiber mechanical properties of concrete, long-term performance and durability, and microstructure characteristics. Analysis showed that Aomi mineral fiber can significantly improve the impact resistance of concrete and crack resistance; compared with polypropylene fibers, and concrete has better compatibility; can be used in road, bridge, roof and other impact resistance, fatigue, crack resistance and other demanding projects.
