How to mortar concrete block wall.
Calculating the amount of mortar needed for the joints in a concrete block wall will vary depending on the mortar mix you use.
There are four main types of mortar mix.
Sand also helps the mortar to withstand the bricks weight.
Most cement block walls will use several different types of blocks especially stretchers and corner units.
Step 3 snap a chalk line on each side of the block wall as a reference line.
Although these materials are sturdier than their brick predecessors they re not impervious to damage.
Mortar is the element that bonds bricks or other masonry units together and provides structural capacity to the wall or other structure.
This is vital in wall installations such as with block walls on foundations.
The mortar has to contain enough sand or aggregate to hold up to the wall s weight as pure cement with water cannot hold up.
Step 4 mix mortar.
To determine the width of your future wall decide how many cinder blocks you want to use for the wall width then calculate the width using the block s measurements.
Each row of blocks is joined to the adjoining blocks with either type n above grade or type s below.
Block shapes and sizes are chosen to match the function of the wall and the configuration of the wall.
Most contemporary homes sit on foundations of poured concrete or concrete cinder blocks.
Each type is mixed with a different ratio of cement lime and sand to produce specific performance characteristics such as flexibility bonding.
Layers of mortar hold the cinder blocks in place just as it would in brick walls and seal off gaps between blocks to prevent water from getting into the.
For example if your cinder blocks are 8x8 in 20x20 cm and you want to use 2 blocks to make up the wall s width your total wall width would be 16 in 40 cm.

On average it takes about three bags of cement for every 100 blocks.
Continue stacking the blocks with mortar in between and check to make sure the wall is level with each new layer.
Divide the number of blocks being installed by 33 3 to calculate how many bags are needed.
Lay out the block making sure to leave a 3 8 inch gap between the blocks to allow for the vertical mortar joints i e a typical 8x8x16 block is actually 15 5 8 inches long and 7 5 8 inches high to accommodate the mortar joint.
