See clay and concrete masonry banding details tek 5 2a ref.
Due to the above reasons and many others several shear keys are provided over the cross sections.
Vertical expansion joints are incorporated into the wall to account for expansion due to temperature changes.
Control joints are typically required in exposed above grade concrete masonry walls where net aesthetic shrinkage cracking may detract from the appearance of the wall and to limit moisture or air infiltration.

Expansion joints also work as contraction joints and may have smooth dowels to maintain the plane of the wall.
Since we know the cohesion of the concrete and the surface area of the joint resisting force can be calculated.

Construction joints use construction joints when the c o n c r ete placement.
Backfill and drainage.
If plans call for expansion joints verify the type of joint intended and execute the details carefully so the joint works pro p e r l y.
Backfill and drainage requirements shall be in accordance with.

Construction joints separate adjacent placements of concrete to make large pours manageable.
Precast concrete cantilever wall expansion joints shall be in accordance with the standard specifications section 6 11 3 3.
Expansion joints should be located at intervals up to 90 feet.
Expansion joints that allow completely independent movement between adjoining components are sometimes called isolation joints.
Greased steel dowels are often cast horizontally into the wall to tie adjacent sections together.
Thus we can check the stability.
True expansion joints in cast in place walls are not common.

For cantilevered and gravity walls vertical expansion joint spacing shall be a maximum of 60 feet on.
