Abstract
Systems and methods of imprinting concrete having exposed aggregate. The imprinted concrete system comprises a concrete layer, an imprinted layer disposed on the concrete layer, wherein the imprinted layer comprises a decorative aggregate, and has been imprinted with an imprinting tool. In some embodiments, the decorative aggregate may be at least partially exposed.
Claims6
A method of forming an imprinted concrete system having exposed aggregate comprising:
- forming a concrete layer on a sub-grade layer, wherein the concrete layer comprises a cement, a relatively coarse aggregate, and water of hydration;
- finishing the concrete layer to form a top surface of the concrete layer;
- applying a decorative aggregate to the top surface of the concrete layer;
- imprinting the surface of the concrete layer using an imprinting tool;
- following imprinting the surface, and without a step of finishing the imprinted surface, retarding curing of a top surface of the imprinted layer by applying a retarder, and allowing a remaining portion of the imprinted layer to cure to a greater extent than the top surface;
- and
- waiting a predetermined time, wherein the predetermined time is based on a characteristic of the decorative aggregate;
- and thereafter
- mechanically removing at least a portion of the top surface of the imprinted layer to at least partially expose the decorative aggregate;
- and
- washing the imprinted layer.
