How to estimate amount of cement and sand needed for your block work

In this tutorial I explain how to estimate the amount of cement and sand needed for laying certain amount of block. And also amount of cement and sand needed for plastering a certain area of wall.
An example was treated to the detail. The method discussed in this tutorial can be for estimation of any area of wall or amount of block.

You remain the one person to bring justice to this estimation on this CZcams so far. By the way, kindly avail us how you arrive at 0.275
You swift response will be highly appreciated.
Thanks a lot

How did the Height of the horizontal mortar change into 275mm or 0.275

[@abbafary1445]

The vid is educative sir kudos. My Question here is, how did uou arrived at getting 0.275 vertical mortar? Thank you best regards

[@obadex]

Great work keep it up

[@garpeeroberts5580]

Hi, how did you obtained the 0.275 in the vertical mortar area calculations?

[@theslickking-majura5799]

my question exactly

[@tushabejoseph7377]

And by calculation how did you get the 10 blocks ? Minus assuming

[@folexkendrick]

Please does this account for the plastering too?

[@tushabejoseph7377]

How did you obtain 0.0637 in the calculation of bed mortar/horiz mortar??? . explain am lost from dt very point

🙌🙌🙌🙌

[@theslickking-majura5799]

Sir kindly explain how you arrived at 0.275

[@AguEmmanuel-kn8qt]

Pls how did u get the 0.275

[@temidayoafolabi7344]

for the vertical, the height of the block is 225mm. Now add the 25mm mortar at the top and also the one at the bottom of the block. You will have 25mm + 225mm + 25mm = 275mm, You can check the diagram at 2:44 . Check the red boxes.

Pls how did you arrive at 1.3 and 1.1 as percentage of 30 and 10 respectively

[@temidayoafolabi7344]

This is how, assume the wet volume is 1 cubic meter, we are told that the dry volume is 30% more that the wet volume. What this means is that you will add 30% of wet volume to the 1 cubic meter value of the wet volume.
see,
Wet vol. = 1m3
Dry vol. = (30% of 1) + 1
=(30/100 * 1) + 1
=(0.3 * 1) + 1
= 0.3 + 1
= 1.3.
therefore, for every 1 m3 of wet volume, we have 1.3 m3 of dry volume. 1.3 in other words is a constant.

Can this be applied to solid blocks?

[@9-5data]

Check the channel to see video on solid blocks
