Abstract: Method of forming a concrete slab to reduce or eliminate control joints includes preparing a substantially flat base, overlaying one or more barriers on top of the base, placing a concrete mixture on top of the barrier(s) and base to form a concrete slab, and allowing the concrete to cure without forming control joints. The base is prepared with a flatness of about ±¼ inch over 10 feet. A side edge is prepared along a periphery of the concrete slab by extending a vapor barrier from a bottom surface of the slab up the side edge toward a top surface of the slab and covering the side edge. A plurality of post-tensioning cables are positioned to extend through the slab and configured to compress and assist in controlling accelerated displacement of the concrete slab during curing and shrinkage. The concrete slab is formed of an evenly gradated and low slump concrete having high fiber content, minimized cement content, and maximized size of large aggregate.

Abstract: A cementitious masonry block that exhibits the appearance of finished natural stone comprises at least two substantially parallel stacking sides operable to be installed on or over other blocks to form a block wall. At least one hollow cell is formed in the block to provide a void for structural reinforcing. One or more display faces each exhibits a finish applied by natural stone finishing techniques. The block is formed from a cementitious mixture that is substantially homogenous throughout the masonry block and that, when cured, is substantially matched in color or grain, or both, to the natural stone that is being replicated.
