The present invention relates to a protective coloring material used for concrete surfaces. The coloring material is composed of component A and component B, wherein the
mass ratio of the component A and the component B is 1:2 to 1:4. The component A is composed of the following ingredients, by
mass: 10-20 parts of water, 0.1-0.3 parts of
cellulose, 4-8 parts of elastic latex, 5-10 parts of flexible latex, 0.3-0.7 parts of
polyvinyl alcohol, 0.1-0.3 parts of anti-crack
fiber 1, 0.3-0.8 parts of anti-crack
fiber 2, 0.1-0.5 parts of a dispersant, and 0.1-0.2 parts of a
preservative; and the component B is composed of the following ingredients, by
mass:13-25
cement parts of
cement, 10-15 parts of
coal ash, 20-25 parts of heavy
calcium carbonate powder, 15-30 parts of sand, and0-0.2 parts of
iron oxide black
powder. The protective coloring material used for concrete surfaces of the present invention can has the effect of fair-faced concrete, and has super strong adhesion performance and
weather resistance, so the protective coloring material can provided lasting protection to the concrete.
