Abstract
A building brick includes a through-extending bore of a trapezoidal cross-sectional configuration to ease removal of a building brick from a mold during fabrication. The central bore permits the stacking of the building bricks to include the bottom wall in downward orientation to accommodate a greater quantity of mortar at the base portion thereof for a stable mortar configuration in use. A further embodiment of the invention includes the bottom wall of a concave configuration to assist in the positioning of mortar between adjacent building bricks, as well as a further embodiment including a forward wall flange extending downwardly relative to the concave surface and a second end wall flange to assist in the positioning of mortar between adjacent bricks to secure the mortar in a semi-solid state.
