Hollow concrete block wall thickness.

Concrete blocks are commonly referred to by their nominal sizes. Every block of wall needs to be placed on a secure footing which is made from concrete. 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. Concrete blocks are available in both solid and hollow configurations.

The concrete block is designed so that when the wall or edifice is installed rebar can be placed within the core of the cinder block to reinforce the structure these hollow cores which come in sets of either two or three take up approximately 50 percent of the block s total volume. A block totaling 9 5 8 inches wide is referred to as a 10 inch block because a standard 3 8 inch mortar joint will increase the total width for the course to 10 inches. 5 and is reported. 40cm length x 20 cm width x 4 in thickness 40cm length x 20 cm width x 5 in thickness 40cm.

The hollow block sizes in the philippines are the following. The equivalent thickness is determined in accordance with standard methods of sampling and testing concrete masonry units astm c140 c140m ref. The hollow block sizes in the philippines are the following 40cm length x 20 cm width x 4 in thickness 40cm length x 20 cm width x 5 in thickness 40cm length x 20 cm width x 6 in. Concrete masonry units cmus are manufactured in a variety of sizes.

They are identified by their depth i e. 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. Equivalent thickness is essentially the solid thickness that would be obtained if the volume of concrete contained in a hollow unit were recast without core holes see figure 1. Concrete block nominal vs actual dimensions concrete block cmu sizes.

If you re using standard blocks 8 then your footing should be at least 16 wide. Those that use cinders fly ash or bottom ash as an aggregate material are called cinder blocks in the united states breeze blocks breeze is a synonym of.
