What is the difference between concrete block and cement block?
Cinder blocks are lighter than concrete blocks. A concrete block contains stone or sand which makes it heavier. Cinder blocks don’t have any tensile strength to withstand pressure. Concrete block is a hard, durable substance.

What is the face shell of a CMU?
FACE SHELL – The side wall of a hollow concrete masonry unit.
Are CMU walls filled with concrete?
CMU block foundations often use large (8-in or 10-in wide and 16-in long), hollow concrete blocks. However, sizes can vary depending on the building’s weight load. To optimize strength and stability, workers install the blocks in a running bond pattern and may insert steel reinforcing bars in the core of the blocks.
How high can you build a 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.
How tall can a 6 CMU wall be?
The rule of thumb (and I say rule of thumb because there is not enough data given here for a qualified structural engineer to make a calculation) for a non-reinforced CMU wall is 20t. That results in a 10-foot high maximum for 6-inch CMU.

How long will a cinder block foundation last?
Poured concrete block bases and slab foundations will last for a lifetime, 80 to 100 years or more, given they have been constructed with precision. The termite proofing of the base, 12 years, provided the chemical barriers remain intact.
