Abstract
A method of forming architectural concrete in a quicker and more cost effective manner relative to conventional concrete formation methods. The method includes forming the architectural concrete without the use of a surface retarder, and using prescribed amounts of fine sand and aggregate to allow for creation of the desired aesthetic look of the architectural concrete.
Claims9
A method of forming architectural concrete upon a subgrade, the method comprising the steps of:
- pouring a concrete mixture over the subgrade, the concrete mixture defining an exposed surface;
- broadcasting a prescribed quantity of fine sand over approximately 15-85% of the exposed surface of the concrete mixture;
- broadcasting a prescribed quantity of aggregate over approximately 15-85% of the exposed surface of the concrete mixture;
- and
- manipulating the fine sand and aggregate to simulate the appearance of quarried stone;
- wherein the prescribed quantities of fine sand and aggregate broadcast over the exposed surface of the concrete mixture allow the architectural concrete to be formed independent of applying a surface retarder to the concrete mixture.
