How to Estimate Materials for 5″ Thick Brick Wall????

Brick wall is used to separate a floor in a different usable space. Such as bed room, living room, toilet, kitchen, store etc.

We use different thickness of brick walls for this purpose. The thickness can be 3 inch, 5 inch and 10 inch. We normally make 10 inch thick brick wall at periphery and 5 inch thick brick wall as internal partition wall.

Whatever you are, a house owner, a civil engineer, a construction supervisor, a civil contractor or a builder, you should estimate the required raw materials for the brick walls which you plan to build.

In this post i’ll show you how to estimate the required raw materials for 5 inch thick brick wall. The raw materials we use to make brick wall are brick, cement and sand.

Lets take a 10 feet long and 10 feet high brick wall for our estimation project. Then, area of our wall is,

10′ x 10’= 100 square feet.

As our wall thickness is 5 inch, so the wall’s volume is,

100 sft x 5 inch =41.67 cft (5″ = 0.42)

As we know, we make the masonry brick wall with cement-sand mortar. The ratio of the mortar we use for 5 inch thick brick wall is 1:4.

The brick size we use to make brick wall is 9.5″ x 4.5″ x 2.75″ which will be 10″ x 5″ x 3″ after jointing with mortar.

Volume of one brick with mortar is, 10″ x 5″ x 3″ =0.08715 cft. (1 inch = 0.08 feet)

So, the required bricks for our wall are,

wall volume divide by one brick volume.

That is,

41.67/0.08715 =478 nos. These are required bricks for our wall.

Now, we’ll estimate required mortar. If we deduct the volume of unmortared brick from our wall volume, that is our mortar volume.

Lets see –

Wall volume is 41.67 cft,

Total brick volume (excluding mortar) is,

478 x 9.5″ x 4.5″ x 2.75″ =32.52 cft.

So, the mortar volume is,

41.67-32.52 =9.15 cft.

This is the wet volume of mortar. The dry volume of mortar is,

9.15 x 1.50 = 13.73 cft.

As we know, cement-sand ratio is 1:4, then cement content in dry mortar is,

13.73 /(1+4) x 1 = 2.75 cft

As cement is measured by bag and we know 1 bag contains1.25 cft cement so,

2.75 cft cement equal to 2.75/1.25= 2.20 bag cement.

If we deduct cement volume from dry mortar volume then we will get sand volume.

That means,

13.73 – 2.75= 10.98 cft.

Required materials for 10′ x 10′ brick wall, we found –

Brick – 478 nos, we can assume this 500 nos.

Cement – 2.16 bag, we can assume this 2 bag.

Sand – 10.98 cft, we can assume this 11 cft.

That’s it.

Here is full calculation process,

Wall volume,

10′ x 10′ x 5″=41.67 cft (5″ = 0.42, cft means cubic feet).

One brick volume with mortar,

10″ x 5″ x 3″ =0.08715 cft. (1 inch = 0.08 feet)

Required brick,

41.67/0.08715 =478 nos,

Total brick volume (excluding mortar) is,

478 x 9.5″ x 4.5″ x 2.75″ =32.66 cft.

Wet volume of required mortar is,

41.67-32.52 =9.15 cft.

Dry volume of mortar is,

9.15 x 1.50 = 13.73 cft.

cement content in dry mortar is,

13.73 /(1+4) x 1 = 2.75 cft

2.75/1.25=2.20 bag cement.

Sand volume,

13.73 – 2.75= 10.98 cft
