This means that by the time you’re done reading this post, you will be able to answer questions like: How many bags of cement do i need to lay the blocks? How many trips of sand do i need for the block work
Before we proceed, lets quickly take a good look at the dimensions of a 9 inch block with voids (9 is very popular, known because it is usually used for building in Nigeria)
Having seen the above image comprising of the various sections of a 9 inch hollow block, lets calculate the area of the block that will receive mortar.
How to Calculate the amount of mortar required by a 9 inch block
Quantity of sand required = 6/7 x 1600 kg/m3 = 1371.428 kg
Making allowance for shrinkage between fresh and wet concrete = 1.54 x 1371.428 = 2112 kg
For 9m3 Of mortar;
You Must Provide = 9 x 2112 = 19004 kg of sharp sand + allowance for waste as appropriate.
So you can order 20 tons of sharp sand and 57 bags of cement for this job.
Now i am sure you understand How to estimate the amount of mortar Required To Lay Blocks (Cement and Sand) covering one square meter as well as make estimates for cement mortar.
