用于制备混凝土是废旧橡胶综合利用的重要途径之一,橡胶混凝土具有较好的抗弯性能及抗冲击性能、耐磨蚀性能以及降噪性能,但也表现出较差的工作性能、力学性能、抗氯离子渗透性能和干缩性能,这也限制了橡胶混凝土的推广。本文探讨了橡胶混凝土的主要特点和缺点,并在分析对应成因的基础上,探讨了改善橡胶混凝土性能的主要措施,包括细化橡胶颗粒,外掺矿物掺合料以及橡胶表面改性(NaOH处理、氧化和硫化、UV老化处理、预包覆、硅烷偶联剂)等。 For the preparation of concrete is one of the important ways of comprehensive utilization of waste rubber, rubber concrete has good flexural and impact resistance, abrasion resistance and noise reduction performance, but also showed poor performance, mechanical properties , Resistance to chloride ion permeability and shrinkage properties, which also limits the promotion of rubber concrete. In this paper, the main features and disadvantages of rubber concrete are discussed. Based on the analysis of the corresponding causes, the main measures to improve the properties of rubber concrete are discussed, including the refinement of rubber particles, the addition of mineral admixture and the modification of rubber surface , Oxidation and sulfurization, UV aging treatment, pre-coating, silane coupling agents) and the like.
