Architectural concrete

摘要

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.

1. 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.
