摘要/Abstract

摘要： 将废弃轮胎应用于混凝土制备,是实现路域废弃物资源化利用、回收及低碳绿色建造的有效途径。为进一步扩大橡胶混凝土的应用范围,延长其在复杂环境下的服役寿命,本文对橡胶混凝土的耐久性能进行了系统地归纳与总结。首先介绍了制备橡胶混凝土时常见的橡胶颗粒预处理方法,然后从宏观角度总结了掺入橡胶颗粒对混凝土吸水性能、抗干缩性能、抗冻融性能、抗碳化性能、抗氯离子渗透性能和抗腐蚀性能方面的影响,最后从微观角度探讨了橡胶颗粒对混凝土耐久性能的影响。预处理橡胶颗粒有助于改善橡胶颗粒与混凝土中水泥基体的界面过渡区黏结不足的情况。此外,掺入橡胶颗粒的混凝土结构表现出更好的抗氯离子渗透性能、抗冻融性能、抗碳化性能以及抗腐蚀性能。

Abstract: The application of waste tires to concrete preparation is an effective way to realize the resource utilization, recycling of roadside waste as well as low-carbon green construction. In order to further expand the application range of rubber concrete and prolong its service life in complex environments, this paper systematically summarizes and concludes the durability of rubber concrete. Firstly, this paper introduces the common pretreatment methods of rubber particles for the preparation of rubber concrete, then summarizes the effects of rubber particles on its water absorption, dry shrinkage resistance, freeze-thaw resistance, carbonation resistance, chloride ion permeability resistance and corrosion resistance from a macroscopic point of view, and finally explores the role of rubber particles on the durability of concrete from a microscopic point of view. Pretreatment of rubber particles helps to improve the insufficient bonding at the interfacial transition zone between rubber particles and cement matrix in concrete. In addition, the rubber concrete structures show better chloride ion permeability resistance, freeze-thaw resistance, carbonation resistance and corrosion resistance.

Key words: waste tire, concrete, rubber particle, rubber particle pretreatment, durability
