The circular economy (CE) is widely known for its emphasis on reducing waste and maximizing the use of resources by reusing, recycling, and repurposing materials to create a sustainable and efficient system. The CE is based on 3R-reuse, reduce, and recycle. The aim of this article is to use styrene butadiene rubber dust (SBR) in building material, constituting secondary waste in the production of SBR, which is currently disposed of as landfill. SBR is partly intended to replace the natural raw material sand. The purpose of the final material is to use it for its light weight, insulating properties, or ability to absorb vibrations and sounds. Various shares of SBR dust in mortars were tested. Some of the mortars used SBR thermal pre-treatment at temperatures of 200, 275, and 350 °C. The strength and SEM results are presented. The best pre-treatment for SBR dust is thermal treatment at 275 °C. The maximum usage of rubber dust with thermal treatment is 60% as a sand substitute. The novel finding of this study is the possibility to use more than 30% rubber dust (as a substitute for sand) thanks to pre-treatment, whereby 30% is a common maximum ratio in mortars.
循环经济（CE）因其强调通过材料的再利用、回收和再利用来减少浪费并最大限度地利用资源，从而创建一个可持续且高效的系统而广为人知。循环经济基于3R原则——再利用、减少和回收。本文的目的是将丁苯橡胶粉尘（SBR）用于建筑材料中，丁苯橡胶粉尘是丁苯橡胶生产过程中的二次废弃物，目前作为垃圾填埋处理。丁苯橡胶部分用于替代天然原材料沙子。最终材料的用途在于其重量轻、绝缘性能或吸收振动和声音的能力。对砂浆中不同比例的丁苯橡胶粉尘进行了测试。部分砂浆在200、275和350°C的温度下对丁苯橡胶进行了热预处理。给出了强度和扫描电子显微镜结果。丁苯橡胶粉尘的最佳预处理是在275°C下进行热处理。经过热处理的橡胶粉尘作为沙子替代品的最大用量为60%。本研究的新发现是，通过预处理有可能使用超过30%的橡胶粉尘（作为沙子替代品），而在砂浆中30%是常见的最大比例。
