Title: HYDRATION PROCESSES IN CALCIUM SULFOALUMINATE (CSA) AND CALCIUM SULFOALUMINATE - BELITE (CSAB) CEMENTS
Author: Aliti, Ramadan
Abstract: The focus of this study is to analyze the evolution of the crystalline phases of the two types of cements, calcium sulfoaluminate (CSA) and calcium sulfoaluminate-belite (CSAB), during the process of hydration measured in days. X-ray diffraction (XRD) was applied to characterize the time evolution of the main peaks of ettringite, the key cause of high early strength. Scanning electron microscopy equipped with an energy dispersion system (SEM/EDX) was used for the topographical evolution of surfaces and chemical composition analysis. The XRD and SEM analysis revealed differences in the ettringite peaks between CSA and CSAB. The CSAB type shows more clear needle-like crystals of ettringite and well-shaped crystals. The results indicate microstructural differences in the crystalline and morphology structure between the two types of cement pastes, which affects the early strength values
