What are the dimensions of CMU block?
What are the dimensions of 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).
How high can you build a 12 CMU wall?
It is not uncommon to create designs with an h/t from 32 to 50. That could produce wall heights of up to 33 feet for walls built with 8-inch concrete masonry units (CMU), 41 feet for 10-inch CMU, and 50 feet for 12-inch CMU. Regionally, 14- and 16-inch CMU are available, which extend possible wall heights even further.
What are the dimensions of a concrete building block?
440mm x 100mm x 215mm
Blocks are produced in a broad range of sizes, but for general building work the most commonly used is referred to as a standard block and measures 440mm x 100mm x 215mm (see Figure 2). Usefully, this is the same length as two bricks and the height of three bricks with 10mm mortar joints.
What does a 12 CMU weigh?

How do you size a CMU?
They are identified by their depth – i.e. the thickness of the wall they create. For instance, a 6″ CMU is nominally 6″ deep while a 10″ CMU is nominally 10″ deep….Concrete Block (CMU) Sizes.
| CMU Size | Nominal Dimensions D x H x L | Actual Dimensions D x H x L |
|---|---|---|
| 12″ CMU Half-Block | 12″ x 8″ x 8″ | 11 5/8″ x 7 5/8″ x 7 5/8″ |
How thick is a CMU block?
Typically, concrete masonry units have nominal face dimensions of 8 in. (203 mm) by 16 in. (406 mm), available in nominal thicknesses of 4 , 6, 8, 10, and 12 in. (102, 152, 203, 254, and 305 mm).
How heavy is a 12 concrete block?
You can expect an average cinder block weight to be about 35 pounds (16 kg) for a standard cinder or concrete block. The standard size in the U.S. measures to be 8-inch by 8-inch by 16-inch….Types of Cinder Blocks (with their weight)
