Abstract
A method of forming an architectural concrete structure having a desired look (i.e., color) and texture, wherein the method generally includes pouring a base concrete layer using conventional concrete. A surface concrete mixture is prepared and includes a mixture of sand and small aggregates to give the surface concrete mixture the desired color and texture for the architectural concrete structure. The base concrete layer provides strength and durability to the concrete structure, while the surface concrete layer provides the desired look and texture of the concrete surface. The surface concrete mixture preferably includes small aggregates to create a smooth and uniform texture.
Claims18
A method of forming architectural concrete, the method comprising the steps of:
- pouring a base concrete mixture to define a base concrete layer having an exposed upper outer surface, the base concrete mixture including cement and large aggregate;
- preparing a surface concrete mixture including cement, small aggregate, and sand, the small aggregate being smaller than the large aggregate used in the base concrete mixture, the small aggregate and sand being mixed into the surface concrete mixture to define a prescribed color;
- and
- pouring the surface concrete mixture over the exposed upper outer surface of the base concrete layer while the base concrete mixture is in an unhydrated state to enable bonding between the surface concrete mixture and the base concrete mixture, the surface concrete mixture defining a surface layer over the exposed base concrete layer.
A method of forming an architectural concrete surface over a base concrete layer formed from cement and large aggregate, the method comprising:
- preparing a surface concrete mixture including cement, sand, and small aggregate, the small aggregate being smaller than the large aggregate in the base concrete mixture, the small aggregate and sand being mixed into the surface concrete mixture to define a prescribed color;
- and
- pouring the surface concrete mixture over the base concrete layer while at least a portion of the base concrete layer is in an unhydrated state to enable bonding between the surface concrete mixture and the base concrete mixture, the surface concrete mixture defining a surface layer.
