What is CMU construction?

Characteristics of Concrete Block Concrete block is made from Portland Cement, aggregates and water. It is also known as a concrete masonry unit (CMU). As a building material, concrete offers several attractive characteristics to designers and builders, including the following: Durable.

What is the standard size of a besser block?

390mm long x 190mm
Off the shelf, a standard Besser Block measures 390mm long x 190mm high x 190mm wide. But when it is laid in a 10mm mortar then those dimensions become 400mm long x 200mm high (x 190mm wide). You can also find Besser blocks in these sizes: 390mm long x 190mm high x 140mm wide.

How wide is a CMU block?

In the US, CMU blocks are nominally 16 in (410 mm) long and 8 in (200 mm) wide. Their actual dimensions are 3⁄8 inch (9.5 mm) less than the nominal dimensions (to allow for 3⁄8-inch mortar joints between blocks in any orientation).

Is CMU cheaper than brick?

Both bricks and concrete masonry are relatively inexpensive. As of 2011, a single clay brick costs about $1.50, while an 8 inch concrete block costs about $1.35. Special lightweight blocks can cost as much as $3.00 each. Labor can bring wall prices up significantly, however.

What dimensions are concrete blocks?
