摘　　要：工业副产石膏作为化工生产过程中产生的副产品,如果不能合理利用而长期堆放,不仅会污染环境,而且造成资源浪费。石膏基复合胶凝材料能实现工业副产石膏低能耗、高值利用,是对其高效利用有效途径之一,但是存在质量不稳定、耐水性差、强度低等问题。针对工业副产石膏综合利用的现状及存在的问题进行了分析讨论,从矿物掺合料、水泥类水硬性胶凝材料、外加剂3个方面对工业副产石膏改性进行了分析研究,并对工业副产石膏基复合胶凝材料目前存在的问题以及未来的发展提出了新思路,为解决工业副产石膏的高值利用提供了技术支撑。Industrial by-product gypsum,a by-product of chemical manufacturing,is often stockpiled,leading to environmental pollution and resource wastage when not effectively utilized.Transforming this material into gypsum-based composite cementitious materials is regarded as a low-energy and high-value approach to improving its utilization.However,issues such as inconsistent quality,poor water resistance,and low strength have been noted.In the study,the current status and challenges associated with the utilization of industrial by-product gypsum are examined.Modifications are analyzed from three perspectives:mineral admixtures,hydraulic cementitious materials such as cement,and chemical admixtures.Recommendations are provided to address existing challenges and guide future development,offering technical support for the high-value utilization of industrial by-product gypsum.
