Masonry walls have an endothermic effect of its hydrates, as in chemically bound water, unbound moisture from the concrete block, and the poured concrete if the hollow cores inside the blocks are filled. Masonry can withstand temperatures up to 1,000 °F (538 °C) and it can withstand direct exposure to fire for up to 4 hours.

A standard 8-inch CMU block is exactly equal to three courses of brick. [3] A bond (or bonding) pattern) is the arrangement of several courses of brickwork. [2] The corners of a masonry wall are built first, then the spaces between them are filled by the remaining courses. [4]

Another common design of this is modest 'pigs ears', which are placed on walls and benches. [3] [better source needed]
