    Effect of modified phosphogypsum on the dimensional stability of supersulfated cement-based materials by Qingqing Jin, Lu Wang, Zhisheng Ren, Xinyu Li, Shuhua Liu

    Published 2025-07-01
    “…Taking the point of decrease in internal relative humidity as the time-zero of autogenous shrinkage, the lime neutralized PG (NPG) reduced the autogenous shrinkage of SSCM by 15.03 % at 28 days and 16.26 % at 90 days, suppressing the development of autogenous shrinkage in SSCM. However, the calcined PG (CPG) displayed the opposite trend. Both modified PG improved the drying shrinkage of SSCM, and the NPG resulted in less water loss. …”
