—This study focused on the recycling and optimal use of colemanite waste (CW) in floor tile/tiles (FT) production. Experimental compositions were prepared with various concentrations of CW calcined at 800°C and FT body. The sinterability at low temperatures (1000–1100°C) and the effect of calcined CW on FT properties were investigated. The physical-mechanical properties of the tiles were characterized by linear shrinkage, water absorption and bending strength tests. The microstructure and the phase development of the tiles were determined by SEM-EDX and XRD, respectively. The optimal tile compositions in conformity with the related standards were obtained at 1050°C (30 wt % CW) and 1100°C (5 and 10 wt % CW). The tiles produced with high ratio CW (30 wt %-1050°C) additions had 0.32% water absorption, 5.70% linear shrinkage, and 52.43 MPa bending strength values. The CW calcined at 800°C was favourably used in FT production to lower the sintering temperature with a new possibility to recycle this waste and conserve natural resources.

抽象

—本研究重点关注地砖/瓷砖 (FT) 生产中硬硼酸钙石废料 (CW) 的回收和优化利用。实验组合物是用在 800°C 下煅烧的不同浓度的 CW 和 FT 体制备的。研究了低温 (1000–1100°C) 下的可烧结性以及煅烧 CW 对 FT 性能的影响。通过线性收缩、吸水率和弯曲强度测试来表征瓷砖的物理机械性能。分别通过 SEM-EDX 和 XRD 测定瓷砖的微观结构和相发展。符合相关标准的最佳瓷砖成分是在 1050°C（30 wt% CW）和 1100°C（5 和 10 wt% CW）下获得的。添加高比例 CW（30 wt%-1050°C）生产的瓷砖具有 0.32% 的吸水率、5.70% 的线性收缩率和 52.43 MPa 的弯曲强度值。在 800°C 下煅烧的 CW 被有利地用于 FT 生产，以降低烧结温度，为回收废物和保护自然资源提供了新的可能性。
