摘要:

全球废轮胎累积量逐年攀升,将废轮胎破碎制备的橡胶颗粒(CR)取代部分混凝土细骨料制成橡胶混凝土(CRC),是实现废轮胎规模化消纳与高值化利用的重要途径,同时可以提升混凝土韧性、抗冻性和隔热降噪等性能。然而,CRC基本力学性能往往较普通混凝土有所下降,这直接限制了CRC的推广应用,使CRC性能优势难以充分发挥。本文以国内外CRC基本力学性能相关研究为对象,采用文献聚类方法分析CRC领域的研究重点,系统梳理CR取代率、粒径及改性处理对CRC抗压强度、劈裂抗拉强度与抗折强度的影响规律;并结合微观结构特征分析其力学性能劣化机制;同时总结细观数值模拟的研究进展,形成了涵盖宏观、细观与微观的综述框架。结果表明,10%(体积分数)的CR取代率是保障CRC力学性能与工程适用性的临界阈值,复合改性方法可有效提高CRC力学强度,而界面过渡区厚度与有害孔隙占比是关联微观结构与宏观力学性能的核心指标。

Abstract:

The global cumulative amount of waste tires is increasing year by year. Replacing part of the fine aggregate in concrete with crumb rubber particle (CR) produced from crushed waste tires to prepare crumb rubber concrete (CRC) is an important approach for large-scale consumption and high-value utilization of waste tires. Meanwhile, this modification can enhance the toughness, frost resistance, thermal insulation, and noise reduction properties of concrete. However, the basic mechanical properties of CRC are often lower than those of ordinary concrete, which directly restricts its popularization and application, failing to give full play to its performance advantages. Focusing on domestic and international studies related to the basic mechanical properties of CRC, this paper adopted the literature clustering method to analyze the research focus in the CRC field. It systematically sorted out the influence regularities of CR replacement rate, particle size, and modification treatments on the compressive strength, splitting tensile strength, and flexural strength of CRC. The deterioration mechanism of its mechanical properties was analyzed by combining with the characteristics of microstructure. In addition, the research progress of mesoscale numerical simulation was summarized, and a comprehensive review framework covering macroscale, mesoscale, and microscale was established. The results indicate that a 10% (volume fraction) CR replacement rate is the critical threshold to ensure the mechanical properties and engineering applicability of CRC. Composite modification methods can effectively improve the mechanical strength of CRC, while the thickness of the interfacial transition zone (ITZ) and the proportion of harmful pores are the core indicators linking microstructure to macro-mechanical properties.
