Abstract
A mold for making dry cast concrete blocks includes a pair of vertical shoulder forming sections, one along each of the opposite sides of the mold to form vertical front shoulders of a block. Each shoulder forming section has a shoulder roughening arrangement to result in molded, roughened shoulders of the block. Methods of making such blocks and the resulting block are included.
Claims7
A wear plate for forming a rounded vertical shoulder of a dry cast concrete block, the wear plate comprising:
- (a) a plate body having a top edge and bottom edge, a molding face between the top and bottom edges, an outside face opposite of the molding face, and a side bridging the molding face and outside face;
- (i) the molding face defining at least one concave shaped molding surface for forming a rounded shoulder and including a recess;
- (ii) the recess extending from adjacent the bottom edge of the plate body and extending upward between about 25% and about 50% of the height of the plate body;
- (iii) the concave shaped molding surface having a smooth section and a roughening section, the roughening section being within the recess;
- and
- (iv) at least two spaced ribs in the roughening section, each rib extending in a direction across the width of the recess and being inclined relative to the side of the plate body.
