Abstract
Calcium sulfoaluminate belite (CSAB) cement clinkers were produced using two industrial by-products: ladle slag and phosphogypsum. The phase composition of the produced clinkers was identified using quantitative XRD analyses, and the chemical composition of the clinker phases produced from phosphogypsum was established using FESEM-EDS. We demonstrate that ladle slag and phosphogypsum can be used as alternative raw materials for the production of CSAB cement. We also show that phosphorous from the phosphogypsum can be incorporated into the larnite crystal structure. The mechanical properties of the hydrated/hardened cement are also presented and are comparable with those produced from reagent-grade materials.
