The influence of the use of recycled rubber in concrete on its selected properties

The paper deals with the area of the use of recycled materials with regard to the potential of sustainable development of the construction industry. The need for recycling and new solutions in materials engineering is constantly growing. Potential sources of recycled raw materials also include rubber recyclate, where two mixtures with different proportions of recycled rubber are compared within the proposed experimental program. The researched mixtures reflect the need for local resources, which also reflects the needs of the circular economy. The experimental program is focused on typical mechanical properties, which are supplemented by specialized tests. Among the results of the experimental program is that with significant proportions of rubber granulate, not only the mechanical properties are affected, but also the durability is significantly affected with regard to the action of the external environment.

本论文聚焦再生材料在建筑业可持续发展潜力相关的应用领域。材料工程领域对废弃物回收及新型解决方案的需求持续攀升。再生原材料的潜在来源亦涵盖橡胶再生料，本研究拟定的试验方案将对两种掺配比例各异的再生橡胶混合料开展对比测试。本次研究的混合料方案贴合本地资源利用需求，契合循环经济的发展要义。试验方案以典型力学性能测试为核心，并辅以专项试验予以补充。试验结果表明，当橡胶颗粒掺配比例较高时，不仅材料的力学性能会受到影响，其在外界环境作用下的耐久性亦会出现显著变化。
