Tests and experience have fairly well circumscribed the use of mineral coloring matter in concrete. One cannot say that any mineral coloring used in concrete will give a permanent color for weathering can spoil any color. Weather action, coupled with the effects of the chemical rays of the sun and the action of the alkalies resulting from the hydration of the cement, gives complex reactions which make necessary the most careful selection of colors with regard to permanency.
