The phosphogypsum-containing paste exhibits relatively high UCS at 28 days, indicating that low-pH phosphogypsum can also serve as a suitable gypsum component in supersulfate cement. Increasing gypsum content leads to a decreasing trend in UCS, although the strength values of pastes with 10 % and 15 % gypsum content are very close.
