Thermogravimetric analysis (TGA) and differential thermogravimetry
(DTG) were used to monitor the hydration progress during the first 28
days. For MA sample, Fig. 5,weight loss was observed in the temperature
region below 200 °C. This is usually associated with the C–S–H gel
decomposition and its gradual increase indicated the increasing
formation of this phase during hydration. The weight loss at about
400 °C can be assigned to CH [24], which was most probably formed
during the hydraulic reaction of β- and γ-C2S [25]
