Abstract: A building material made by the method of producing artificial fossil coral which is an artistic replica of a natural coral reef rock by forming a slurry of cement or concrete. Pouring or casting the slurry into a mold of desired shape including driveway sections, walkway sections, patios, or pavers. Broadcasting and impressing into the exposed malleable surface of the cement or concrete a selection of additives with self sustaining shapes including exoskeletons of marine organisms and other debris normally incorporated into natural coral. After the cement or concrete is set-up, the surface is flooded with liquid to dissolve the formed additives leaving voids simulating the surface of natural coral rock.
