the only noticable differance between white and grey cement is white is twice the price.

here is a Q&A right from Portlands website

"
What is white portland cement?
White portland cement has essentially the same properties as gray cement, except for color, which is a very important quality control issue in the industry. It is readily available throughout North America.
The color of white cement depends on raw materials and the manufacturing process. It is the metal oxides (primarily iron and manganese) that influence the whiteness and undertone of the material. White cement is manufactured to conform to ASTM C 150, Specification for Portland Cement. Although Types I, II, III, and V white cements are produced, Types I and III are the most common."

FYI, you need silica in any cement as one of the 4 basic ingreadiance, so you will never find cement with out silica.
