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.
