Figure 5.
The six line graphs plot D T G in per cent per minute against temperature in degrees Celsius. Panels A to C compare C E M one, and Panels D to F compare C E M three. Panel A represents the 0 to 63 micrometre fraction. Panel B represents the 63 to 125 micrometre fraction. Panel C represents the 125 to 250 micrometre fraction. Panel D represents the 0 to 63 micrometre fraction. Panel E represents the 63 to 125 micrometre fraction. Panel F represents the 125 to 250 micrometre fraction. Each panel compares alpha one and alpha two curves. The curves contain annotated regions for C S H phases and bound water, Portlandite where present, and Carbonates. The curves show similar overall profiles, with an initial trough at lower temperatures, additional troughs near the Portlandite region where present, and a pronounced trough in the Carbonates region before rising sharply at higher temperatures.DTG of fractions: (a) 0–63 µm; (b) 63–125 µm; (c) 125–250 µm for each angle (α1 = 90° and α2 = 85°) of CEM I samples and (d)–(f) for CEM III, respectively
