摘　　要：与普通混凝土相比,活性粉末混凝土具有优异的力学性能和耐久性,多用在土木、核工程、海洋、军事等工程中。然而,活性粉末混凝土也具有脆性的特点,因此掺入纤维能有效地降低活性粉末混凝土内部孔隙率,减小微裂缝,进而提高活性粉末混凝土的密实度、强度和韧性。通过分析纤维种类与掺量对活性粉末混凝土力学性能的影响,初步确定各类纤维的最佳掺量,混杂纤维的最佳组合为玄武岩纤维和聚丙烯纤维,总结活性粉末混凝土在工程中的研究和应用现状。Compared with ordinary concrete,reactive powder concrete has excellent mechanical properties and durability.It is often used in civil,nuclear engineering,marine,military and other projects.However,reactive powder concrete also has the characteristics of brittleness,so adding fiber can effectively reduce the internal porosity and micro cracks of reactive powder concrete,and then improve the compactness,strength and toughness of reactive powder concrete.By analyzing the influence of fiber type and content on the mechanical properties of reactive powder concrete,the optimal content of various fibers is preliminarily determined,the best combination of hybrid fibers is basalt fiber and polypropylene fiber.The research and application status of reactive powder concrete in engineering are summarized.
