Using phosphogypsum to make a special type of cement can be helpful. By adding certain minerals like C$H2 and CH, the strength and hydration of the cement can be changed. Adding C$H2 can make the cement stronger, but too much can make it weaker. Adding CH can make the cement weaker at first, but then it gets stronger. The best mix is when there is a certain amount of CH added to the cement. This study shows how these minerals affect the cement's strength and how to find the best mix for making strong cement.
