Definitions

  • This invention relates to coloring cement.
  • Numerous methods have been employed to color cement-containing products formed of mortar and concrete to make the products appear to be formed of a natural stone. Many of these processes involve mixing of coloring materials with the cement, together with complex and expensive drying, heating, and grinding steps. Also, it is known that large proportions of mineral pigments are often reguired to produce the desired color in hardened cement products, making the coloring process uneconomical.
  • the invention features a method of coloring the surface of a pre-formed cement-containing product by applying a metal sulfate to a surface of the product in the presence of water, e.g., in the form of an aqueous solution.
  • Ferrous sulfate, copper(II) sulfate, and manganese sulfate can be used in the method.
  • the cement-containing product can be cured or green (uncured) , and can be, for example, mortar or concrete. The color achieved is relatively permanent and colorfast, and gives the product the natural appearance of stone.
  • the colorant applied to the cement article according to this invention is neither a stain nor is it a paint. In fact it is applied from an aqueous phase not from an organic chemical phase, as would be the case where a stain was used, nor is the colorant applied in conjunction with the laying down of a film, suitably an organic polymer film, on the cement article surface. It can generally be said that according to the process of this invention, the metal sulfate colorant is applied to the preformed cement article surface in the substantial absence of organic polymers or solvents or other organic phases which would cause partition of the metal sulfate out of an aqueous phase, which seems to be required for the practice of this invention.
  • the process provides an economical method of coloring cement-containing materials such as stuccoed buildings and walls, concrete slabs and blocks, stamped concrete floors, concrete structures such as buildings and bridges.
  • the economy provided by the process results at least in part from the recognition that only the surface of the product needs to be coated to obtain a durability of color.
  • the coloring solution is inexpensive, easy to apply (e.g., by spraying, brushing, mopping or pouring onto the surface) under normal conditions (e.g., in the open air), and relatively non-toxic in the concentrations used. Also, any surface area damaged after the initial application of the coloring solution may be easily and conveniently re-colored.
  • an aqueous solution of the metal sulfate is applied to a surface of the cement-containing product.
  • the concentration preferably is between 27 to 429 grams (one-quarter ounce and four ounces) of metal sulfate, dry-weight, per liter of water; the concentration will determine the shade of color achieved. For example, low concentrations of ferrous sulfate will result in a yellowish tan surface, while high concentrations will give a reddish brown color.
  • the wearability of the color imparted by the method results from a chemical reaction in which the sulfur in the sulfate acts as a bonding agent between the metal ion and the calcium carbonate in the cement, with water being the activating agent.
  • the reaction between ferrous sulfate and cement is thought to be as follows:
  • the ferrous ion which is responsible for the color,is chemically bonded to and becomes an integral part of the cement.
  • the color imparted will thus last as long as the surface of the cement.
  • Example 1 is illustrative of the method.
  • the coloring solution prepared in Example 2 is mixed with a latex based drying inhibitor that is commonly used to slow down the drying time for mortar or concrete. When applied to wet or uncured mortar or concrete, a dark reddish brown color will result.
  • Copper(II) sulfate and manganese sulfate solutions have given similar results, with the copper(II) sulfate imparting a blue green color to the surface and the manganese sulfate a gray brown color.
