The invention involves an exposed aggregate architectural coating to be applied to existing concrete structures. The invention includes a method of preparing and roughening an existing concrete structure surface, mixing the components of the exposed aggregate architectural coating, applying the coating to the existing concrete structure, spreading the coating to a thickness of one-fourth of an inch or thinner, using a trowel, gauge rake, or other method to smoothen the coating, allowing the coating to cure, applying a surface retarder once the exposed aggregate architectural coating has stiffened, allowing the surface retarder to cure for twenty-four hours, and washing the surface with a pressure-washer to remove the surface retarder, then acid-washing the surface to remove residue and create a desired texture. The resulting applied exposed aggregate architectural coating will have an exposed aggregate finish that is durable and suitable for high vehicular and pedestrian traffic areas.

Disclosed herein are composite materials, including composite building materials, comprising a polyurethane composite core in physical communication with a cementitious layer. Also disclosed are methods for producing the composite materials.

Disclosed herein are composite materials, including composite building materials, comprising a polyurethane composite core in physical communication with a cementitious layer. Also disclosed are methods for producing the composite materials.

Disclosed are methods and solutions for sealing and curing concrete and other cementitious materials using strontium containing, non-alkali, non-silica, chemical solutions. The strontium-based solutions can be placed in admixture with cementitious materials prior to molding and curing to create a final product, or the strontium-based solutions can be applied to newly created or existing cementitious material surfaces to improve the repellent and stain, resistant properties.

Methods for embedding photocatalytic titanium dioxide in asphalt surfaces to reduce pollutants via photocatalytic reactions include applying an amount of an asphalt surface treatment compound to an upper surface of the asphalt surface, the asphalt surface treatment compound including a mixture of a liquid carrier compound with a titanium dioxide (TiO.sub.2) photocatalyst.
