摘要: 玄武岩纤维活性粉末混凝土是一种新型的超高性能水泥基复合材料。室内力学性能和耐久性能试验表明,该材料具有超高强度和高耐久性。依托吉林省集安至双辽高速公路项目,将玄武岩纤维活性粉末混凝土应用于某桥梁防撞墙实体工程。根据施工情况,介绍了玄武岩纤维活性粉末混凝土的施工工艺,并总结了施工过程中出现的问题,提出了相应的改进措施。Abstract: Basalt fiber reactive powder concrete is a kind of innovative cement-based composite material with ultra-high performance. Laboratory tests on mechanical properties and durability show that basalt fiber reactive powder concrete has ultra-high strength and durability. Relying on Jilin province Ji’ an-Shuangliao expressway project,basalt fiber reactive powder concrete is applied to an anti-collision wall project of bridge. The construction technology of basalt fiber reactive powder concrete is introduced in the paper,and the problems in construction process are summarized,and the corresponding improvement measures are put forward.
