Concrete masonry units also known as cmu are blocks used in the construction industry to form a concrete block structure like a wall or a fence.
Hollow concrete block wall construction.
However hollow concrete block walls are not structurally very strong and will not resist the flexural stress that a wall is subjected to causing them to collapse easily.
In this case the top of the excavation is sometimes.
The concrete foundation needed to support a cement block wall is usually created by pouring concrete into a hollow form lining the sides of the excavation trench but the concrete can also simply be poured into the trench a common scenario for construction of a freestanding landscape wall.
Flexural stress comes from the pressure of the load the walls bear from the upper.
1 solid concrete blocks and 2 hollow concrete blocks in this article we are discussing both the varieties yet latter in more detail.
These are generally made up of concrete and aggregates of certain design mixtures depending on strength required but systems used as masonry units are non load bearing in nature or do not and should.
A concrete masonry unit cmu is a standard size rectangular block used in building construction cmus are some of the most versatile building products available because of the wide variety of appearances that can be achieved using them.
A concrete block is referred to as a concrete masonry unit or cmu in the construction industry.
The concrete blocks are available in two variations.
Concrete blocks can be solid or hollow with two or three cores or voids.
