2021-5-1 · An I-Cal 8000 high precision calorimeter provided by Calmetrix was used to measure the heat evolution of the white cement clinker. White cement clinkers that passed through the 75 μm sieve were mixed well with 5 wt% gypsum in an agate mortar. The 50 g cement was placed into a plastic cup. Then, it was mixed well with 25 g water for 30 s.

2016-5-25 · In white cement, the whiteness index is a very important parameter to control. However, white cement contains a very low amount of iron since it decreases the whiteness, which implies insignificant content of C4AF. Therefore, white clinker contains three major constituents: C3S, C2S, and C3A .
