Abstract
A concrete coloring material and a process for coloring concrete by means of such a concrete coloring material capable of permitting concrete to exhibit natural color or aesthetic properties while preventing concrete from being substantially discolored. Polyethylene oxide is used as a water-soluble adhesive or glue. The oxide is mixed with a composition such as dye, pigment, a mixture thereof or the like, to thereby permit the composition to penetrate into the concrete.
Claims11
A concrete coloring material comprising:
- a concrete penetration layer of 30 to 200 .mu.m in thickness formed of polyethylene oxide of a molecular weight of about 100,000 to 5,000,000 prepared by ring opening polymerization of ethylene oxide and a composition selected from the group consisting of dye, pigment and a mixture thereof;
- and
- a substrate on which said concrete penetrating layer is deposited, said substrate comprising a pattern formwork for concrete formed with an unevenness in contrast and an uneven pattern which develops on a surface of concrete which is formed.
A concrete coloring material comprising:
- a concrete penetration layer of 30 to 200 .mu.m in thickness formed of polyethylene oxide of a molecular weight of about 100,000 to 5,000,000 prepared by ring opening polymerization of ethylene oxide, a composition selected from the group consisting of dye, pigment and a mixture thereof and a surface-active agent made by fermentation and acting as a dispersant for said composition;
- and
- a substrate on which said concrete penetrating layer is deposited, said substrate comprising a pattern formwork for concrete formed with an unevenness in contrast and an uneven pattern which develops on a surface of concrete which is formed.
