Recent investigations have revealed the great potential of Raman spectroscopy for the characterization of clinker minerals and commercial Portland cements. The usefulness of this technique for the identification of anhydrous, hydrated, and carbonated phases in cement‐based materials has been demonstrated. In the present work, the application of micro‐Raman spectroscopy for the characterization of the main clinker phases of calcium aluminate cements and calcium sulfoaluminate cement is explored. The main stable hydrated phases as well as several important carbonated phases are investigated. Raman measurements on the following phases are reported: (i) pure, unhydrated phases: CA, C₁₂A₇, CA₂, C₂AS, cubic‐C₃A, C₄AF, and C₄A₃; (ii) hydrated phases: ettringite, monosulfoaluminate, and hydrogarnet (C₃AH₆); (iii) carboaluminate phases: hemicarboaluminate and monocarboaluminate. The present …
