Morphological Analysis of White Cement Clinker Minerals

Morphological Analysis of White Cement Clinker Minerals

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 .
