Exposed aggregate concrete is a decorative style of concrete suitable for use as a driveway, sidewalk or patio. The appeal is in the finish, which exposes the smooth textured small stones and pebbles that are part of the concrete.
Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete.
