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).
What is the difference between a cinder block and concrete block?
Cinder blocks are hollow rectangle-shaped structures usually made of concrete and coal cinders which find use in construction sites. Concrete blocks often, on the other hand, are flattened constructs made of steel, wood or cement.
Do I need to fill cinder blocks with concrete?
It is common practice to fill the holes of cinder blocks with rebar and then add concrete within to strengthen them. However, when doing so, it is important to take note of the climate you’re working in.
