AB Yeelimite-containing cements are attracting attention for their tailored properties. Calcium sulfoaluminate,CSA, cements have high contents of Yeelimite and they are used for special applications. Belite calciumsulfoaluminate, BCSA or sulfobelite, cements have high contents of belite and intermediate contents ofYeelimite, and they may become an alternative to OPC. Here, we report Rietveld quantitative phase analysesfor three commercially available CSA clinkers, one CSA cement, and two laboratory-prepared iron-rich BCSAclinkers. The crystalline phases are reported and quantified. Selective dissolutions are employed for BCSAclinkers to firmly establish their phases. Finally, the overall unaccounted contents (amorphous plus crystallinenot quantified) have been determined by two approaches: i) external standard procedure (G-method) withreflection data; ii) internal standard procedure (spiking method with ZnO) with transmission data. The overallunaccounted contents for CSA clinkers were ~10 wt.%. Conversely, the unaccounted contents for BCSA clinkerswere higher, ~25 wt.%.
