Abstract
A decorative concrete with a very uniform finish surface and a method of fabricating the same is disclosed. A concrete mixture is poured over a subgrade which defines an exposed surface. The exposed surface is finished with any of several techniques, and the surface is then worked with an abrasive material, and additional techniques are used to color and seal the concrete.
Claims17
A method of forming a decorative concrete slab having a smoothed exposed surface, comprising:
- pouring a concrete mixture over a subgrade, the concrete mixture having sand particles therein and defining an exposed top surface when poured;
- allowing the concrete mixture to harden, such that sand particles at the exposed top surface are integrated into the hardened concrete mixture to define an unevenness of the exposed top surface;
- and
- moveably applying an abrasive member over the exposed top surface to remove certain ones of the sand particles integrated therein to reduce the unevenness of the exposed top surface.

A method of forming a concrete structure, the method comprising the steps of:
- pouring concrete over a subgrade, the concrete having sand particles therein;
- screeding the poured concrete to remove excess concrete to define a top surface at a desired plane;
- surface finishing the top surface with a finishing tool;
- allowing the concrete mixture to harden, such that sand particles at the top surface become rigidly formed in the concrete and define an unevenness at the top surface;
- and
- applying an abrasive member over the top surface to dislodge certain ones of the sand particles at the top surface to reduce the unevenness at the top surface.
