As a special cement-based material, low pH value cement-based materials are mainly used in the solidification engineering of medium and low radioactive waste, heavy metal pollutants and the engineering of high-level radioactive waste repositories. This review analyzed the main influencing factors and changes of pore solution pH value of blended Portland cement, magnesium silicate cement and magnesium phosphate cement. and summarized the current research work on the flowability, compressive strength, durability and solidification performance of low pH value cement-based materials. In addition, the application of low pH value cement-based materials in the solidification of low or medium radioactive waste and heavy metal contaminant and high-level radioactive repository engineering was also discussed.
