Abstract During the polishing process of ceramic tiles, plenty of ceramic polishing residue (CPR) is generated. In order to evaluate the reutilization of CPR as a supplementary cementitious material (SCM) in mortar/concrete, and investigate its effects on the strength and durability, a series of mortar mixes containing different CPR contents were made for conducting compressive strength test and rapid chloride permeability test. It was found that adding CPR as a SCM up to 20% could still markedly improve the compressive strength and chloride resistance, while at the same time reduce the waste disposal, cement consumption and carbon footprint for sustainable development. Moreover, the cementing efficiency factor of the CPR in 28-day compressive strength was generally higher than 1.5 whereas that in chloride resistance was generally higher than 4.0, indicating that the CPR is a highly effective SCM for replacing part of the carbon-intensive cement and improving the strength and durability performance.

陶瓷抛光渣对砂浆抗压强度和耐氯化物的胶结效率影响因素

摘要 在瓷砖抛光过程中，会产生大量的陶瓷抛光残留物（CPR）。为了评估 CPR 作为砂浆/混凝土中辅助胶凝材料 (SCM) 的再利用，并研究其对强度和耐久性的影响，制备了一系列含有不同 CPR 含量的砂浆混合物进行抗压强度试验和快速氯化渗透性测试。研究发现，添加高达 20% 的 CPR 作为 SCM 仍然可以显着提高抗压强度和耐氯化物性，同时减少废物处理、水泥消耗和碳足迹以实现可持续发展。此外，CPR在28天抗压强度中的固井效率系数一般高于1.5，而在抗氯化物方面的固井效率系数一般高于4.0，
