A variety of specialized shapes exist to permit particular building features. U-shaped blocks or knockout blocks with notches to permit the development of bond beams or lintel assemblies, utilizing horizontal reinforcing grouted into place within the cavity. Blocks with a channel on the end, often recognized as “jamb blocks”, allow doorways to be secured to wall assemblies. Blocks with grooved ends allow the construction of management joints, allowing a filler material to be anchored between the un-mortared block ends. Other features, similar to radiused corners often identified as “bullnoses” may be incorporated. Today, Portland cement stays the most typical sort of cement utilized in constructing supplies.
