White Portland Cement has essentially the same properties as gray cement, except for color. The color of white cement is determined by its raw materials and the manufacturing process. Metal oxides, primarily iron and manganese, influence the whiteness and undertone of the material. White Cement is available in 94 pound sacks at Salmon Bay. Since it is not available in our region in bulk quantities it is not used in any of Salmon Bay’s concrete mixes.We supply both Lehigh as well as Cimsa White Cement products.
