A bonded pilaster may be constructed as an integral part of the wall or, where provisions for crack control are provided such as with control joints, they may be constructed as an unbonded structural member where lateral support is provided through the use of suitable connections. Concrete blocks, also known as Concrete Masonry Units or CMUs, provide very durable structural and non-structural partitions. This creates a very rough texture that some people think looks like stone, especially since the aggregates in the block are also split or exposed. While the primary purpose of a pilaster is to provide lateral support, in many cases it may also be required to support vertical loads such as those imposed by beams or other framing members. ASTM C90 covers most conventional CMU construction and is the standard referenced by the ICC codes. Therefore, it is important that the architect review at least 3 sample blocks that demonstrate the expected color variation. If lateral ties are provided in accordance with ref. endobj xmp.id:7e0768d0-264d-409d-b313-56af2adbeae0 Block textures may vary depending on the unit type and production requirements.
