Abstract
A method and a surface seeded exposed aggregate concrete product are provided that precisely simulate the appearance and qualities of various types of natural quarried stone, such as granite, marble, rhinestone, bluestone, and brownstone, to name a few. Implementations of the present invention are characterized by the use of fine sand and aggregate broadcast over the exposed surface of poured concrete, which surface has been prepared to receive the same. Subsequently, a surface retarder and finishing steps are performed to produce the concrete product which assimilates the characteristics and colors of natural quarried stone, such as speckles, inclusions, flecks, graining, fractures, joints, knots, crystallization patterns, streaks, weathering, etc.
Claims20
A method of producing simulated quarried stone by utilizing a combination of fine sand and surface seeded exposed aggregate upon a subgrade, the method comprising:
- a. pouring a concrete mixture over the subgrade, the concrete mixture defining an exposed surface when poured;
- b. finishing the exposed surface of the concrete mixture to dispose a quantity of cement/fines paste derived from the concrete mixture at the exposed surface thereof;
- c. broadcasting a quantity of fine sand upon the exposed surface of the concrete mixture;
- d. broadcasting a quantity of aggregate upon the exposed surface of the concrete mixture;
- e. mixing the fine sand and the aggregate into the cement/fines paste;
- f. applying a surface retarder to the exposed surface;
- and
- g. massaging the surface retarder into the exposed surface, the fine sand and aggregate mixture simulating characteristics of quarried stone when the exposed surface is cured.
