Abstract
A non-slick surface-seeded exposed aggregate concrete product and method of making the same enhances the coefficient of friction of an exposed surface thereof to reduce undesirable slipping and sliding. Implementations of the present invention are characterized by the use of fine sand and aggregate broadcast over the exposed surface, which surface has been prepared to receive the same. After curing, the exposed surface is then ground and acid-etched to define fissures, cracks, and/or sharp edges of the aggregate. Subsequently finishing steps are performed to produce the non-slick concrete product which may be used for high traffic pedestrian areas where foot gripping and traction are important, such as on stairs, ramps, walkways, courtyards, and the like.
