Abstract：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,hy-draulic cementitious materials such as cement,and chemical admixtures.Recommendations are provided to address existing chal-lenges and guide future development,offering technical support for the high-value utilization of industrial by-product gypsum.
