Petrographical analysis of calcium aluminate cement mortars: Scanning electron microscopy and transmitted light microscopy
The samples studied for this paper were obtained from experimentally induced carbonation and alkaline hydrolysis of calcium aluminate cement (CAC) mortars. The mineralogical composition of phases present was studied from X-ray diffraction (XRD) spectra. Scanning electron microscopy (SEM) and transmitted light microscopy (TLM) were used to obtain some morphological (size and shape) and fabric data of mineralogical phases to improve the interpretation of damage processes. SEM is a useful tool to examine the evolution of mineral phases in cavities and discontinuity zones. The interpretation of the degree of carbonation and the distribution of carbonated phases in the samples, the presence of C3AH6 and CAH10, as well as possible alterations of aggregates are well differentiated and defined using TLM method. The main objective of the present paper is to validate the use of both microscopic techniques (TLM and SEM) for the study of phase evolution in the CAC mortar during curing and degenerative processes.
