Abstract
Abstract A masonry wall is formed of a plurality of masonry blocks, i.e., bricks, with mortar, therebetween and in which spacing of the bricks from each other, both vertically and horizontally, is dictated by plastic spacer elements. The spacer element includes a plurality of connecting struts joined together in a common plane or in planes which are perpendicular to each other. Spacer fingers or protrusions protrude in opposite directions from the struts so as to contact the adjacent surfaces of the blocks and dictate the spacing of one block from the next, accordingly. The spacer elements remain embedded in the mortar.
