Breeze blocks are typical building blocks that are made of concrete and ash. These concrete blocks are usually known as breeze blocks or cinder blocks, even if ash is not present in them. In some parts of the world, these concrete blocks can also be manufactured along with gravel, clinker and sand, used as fillers. Breeze blocks are used in a variety of construction projects. They come in many different weights and densities, depending on the fillers being used and on the manufacturing method being utilized. Usually, for building of walls, lower density breeze blocks are used, while for building foundations, high density blocks are used. Most people use lower density breeze blocks to build garden or garage walls. Here’s how you can build a breeze block wall.
Prepare the Cement -First, the foundation for the breeze blocks will have to be laid. The foundation will be at least twice as wide as the wall. Keeping this in mind, mix the appropriate amount of cement for building a wall.
Lay the Foundation -Use high density breeze blocks to lay the foundation. The foundation should be twice as wide as the width of a breeze block and the depth too should be twice the size of the thickness of the breeze blocks. To level the foundation properly, use a leveler. Wait for the cement on the foundation to dry before putting up additional bricks for the wall.
Lay the First Row -Estimate how many breeze blocks will be needed for each row by simply placing the breeze blocks over the foundation. Do not use the mortar yet. Once you have determined the exact number, use a trowel to lay a layer of mortar on the foundation. Start from the corner so that the wall is even. After applying the mortar, start placing the first row of the breeze blocks. Inside the holes of each of the breeze blocks, pour some mixed cement. This ensures that they are completely fixed. Once the first row is laid, use a level to ensure that the breeze blocks have been laid in perfect alignment. If the blocks are not leveled perfectly, align them, preferably before the cement dries out.
Build the Wall -Let the cement on the first row dry out before placing the second row. Place another layer of mortar on top of the dried row of breeze blocks. Take care to apply mortar on the edges of the breeze blocks as well. Begin from the corner of the first row similarly to the first row, begin to place the breeze blocks for the second row. Key point to note this time however, make sure that the vertical joints are alternated. This gives the wall more strength. In order to do this, you may have to place a smaller block at the corner of the second row. Again pour cement into the holes of the breeze blocks. Continue adding layers in this manner until you have achieved the height desired.
