摘　　要：自密实橡胶混凝土是将废弃轮胎加工成橡胶颗粒并掺加到自密实混凝土中制成的新型建筑材料,相比于常规混凝土,其在硬化后具有脆性低、变形能力强、节能环保的显著优点。为了全面了解自密实橡胶混凝土的最新研究现状,从自密实性能(流动性、粘聚性、间隙通过性、抗离析性)、力学性能(抗压强度、劈裂抗拉强度、弹性模量、抗折强度、抗冲击性能、疲劳特性、阻尼比)、耐久性能(干收缩性能、吸水率、抗冻性、氯离子渗透性、电阻性)和内部微观结构等方面出发,对近十年间国内外针对自密实橡胶混凝土的研究进行了综合介绍。最后,归纳总结了研究结论,并为自密实橡胶混凝土的未来研究与推广提出若干建议。Self-compacting rubberized concrete is a new type of building material made by processing waste tires into rubber particles and adding them to self-compacting concrete.Compared with conventional concrete,it has the obvious advantages of low brittleness,excellent deformability,energy saving and pro-environment after hardening.To understand the latest research status about self-compacting rubberized concrete,the research on self-compacting rubberized concrete worldwide in the past ten years was comprehensively introduced from the aspects of self-compacting ability(flow ability,viscosity,passing ability,segregation resistance),mechanical properties(compressive strength,splitting tensile strength,elastic modulus,flexural strength,impact resistance,fatigue behaviour,damping ratio),durability(drying shrinkage,water absorption,freeze-thaw resistance,chloride ion penetration,electrical resistivity)and internal microstructure.Finally,the conclusions were summarized,and some suggestions were proposed for the future research and promotion of self-compacting rubberized concrete.
