Cement - Composition, Properties, Major Cements: Portland cement is made up of four main compounds: tricalcium silicate (3CaO · SiO2), dicalcium silicate (2CaO · SiO2), tricalcium aluminate (3CaO · Al2O3), and a tetra-calcium aluminoferrite (4CaO · Al2O3Fe2O3). In an abbreviated notation differing from the normal atomic symbols, …

Additionally, the white clinker must be cooled rapidly, often with water, to prevent the oxidation of trace iron impurities that would darken the cement. The higher …

Royal El Minya Cement was established in 2006 for the production of white clinker & cement and has been operating since mid 2010. The Company produces white portland cement and white masonry cement and has an annual clinker production capacity of 450,000 tons. The plant is located in El Minya, Egypt.

In diluted state (isolated substitution), the oscillator forces are severely reduced, changing the colouring effect in mechanism and intensity. The chroma of clinker can be changed by doping with trace elements or adjusting the chemical composition. Li et al. studied the effect of incorporating ZnO on the whiteness of white Portland cement …

White Clinker. The white clinker is composed of 7% tricalcium aluminate, 76% alite, 2% free lime, 15% belite, and no tetracalcium aluminoferrite. These compositions may vary according to the requirements. White clinker is a primary material to produce white cement, which can elevate the overall space look in construction.

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 .
