It is a pure form of OPC. White cement only differs from the ordinary portland cement by its colour. It has a clean & bright colour because of its manufacturing process.
The vanadium, iron, copper, manganese, oxides of chromium & titanium which imparts grey colour to the cement (Clinker) will be limited when manufacturing white cement. The white cement is also finer than the OPC.
The compressive strength of the white cement will have 90% compressive strength of OPC cement.
