WHITE PORTLAND CEMENT- Type I (for molds and casting).

It is great for decorative projects that are tended to have chromatic and bright hues and pigments. Ordinary cement, when used with pigments, produces colors that may be attractive, but are somewhat dull. With white cement, bright reds, yellows and greens can be readily produced. Blue concrete can also be made. The pigments may be added at the concrete mixer.
