Apart from the bricks the next prefered material to construct the wall is Concrete Block. The different types of concrete blocks are listed below.
- Solid Blocks
- AAC blocks
- Concrete bricks
- Lintel and paving blocks
In earlier, we discuss how to calculate the number of bricks and volume of cement mortar and now we are going to discuss How to Calculate Quantity of Concrete Blocks?.
How to Calculate Quantity of Concrete Blocks?
Let us see with an example, now we are going to calculate the number of concrete blocks including cement mortar for 1 Sqm.
Size of Block
Length – 400mm Width – 200mm Depth – 200mm
Mortar Ratio 1:5 and thickness – 10mm
Cement Mortar Calculation for Block Work
In above Diagram,
Volume of Horizontal Mortar Joint – 6 x 0.2 x 0.01 x 1 = 0.012 Cum
Volume of Vertical Mortar Joint – 4 x 4 x 0.2 x 0.2×0.01 = 0.0064 cum
– 0.01×0.14×0.2×4 = 0.00112 cum
Total volume = 0.012+0.0064+0.00112 = 0.0195 Cum
So the volume of required Mortar for 1 Sqm block Work – 0.0195 Cum
In earlier, we have explained How to calculate the Cement and Sand for mortar.
Concrete Block Calculation
Size of the Block – 0.4 x 0.2
– 1/(0.4 x 0.2) = 12.5 Nos
Now the required number of concrete blocks – 12.5 Nos
You may use the below calculator for calculating the number of blocks and cement mortar volume.
