PRECISION GROUND CONCRETE MASONRY BLOCKS AND SYSTEM AND METHOD FOR THE HIGH-SPEED APPLICATION OF MORTAR/GROUT TO PRECISION GROUND CONCRETE MASONRY BLOCKS AND SELF-LEVELING INSTALLATION OF CONCRETE MASONRY SYSTEMS

摘要

A stackable building block (1102) for constructing a masonry wall includes a front section having an outer surface, an inner surface, a bottom surface, and a top surface (1109). The top surface (1109) includes one or more regions (1500 and 1502) having a higher surface height that is manufactured and then precision ground to the desired height and positioned between or next to lower surface areas (1113). The building block (1102) also has a rear section substantially parallel to the front section and similarly arranged. The top surface may include a tapered region beginning proximate at least one of the side or end regions and tapering outwardly away from the side toward the center of the block. The tapered region may include an indentation. The tapered region and indentation provide a true mortar joint capability and resistance to water infiltrating the joint. During assembly of the stack building block, a thin set mortar, grout or adhesive is used between successive courses and that is applied using a high speed applicator.
