Let us consider an AAC block wall of size 3m. × 10m. × 0.2m. as shown in the drawing.

**200 mm × 200 mm × 600 mm**as shown in the image below.

**4mm.**thickness for the calculation purpose.

__Given data:__Length of the block wall = 10m.

Height of the block wall = 3m.

The thickness of the block wall = 0.2m.

AAC block size = **0.2m ****× 0.2m ****× 0.6m.**

Adhesive joint thickness = 4mm = 0.004m.

**The volume of the block wall**

**6 CUM.**

**Now, the volume of the AAC block**

**00 mm × 200 mm × 200 mm**

**0.6m**

**× 0.2m**

**× 0.2m.**

**0.024 CUM.**

From the drawing given below, you can observe that the addition of the adhesive thickness comes on the 2 sides of every block. I have denoted them with the nos. 1, & 2.

So, the volume of the AAC block with adhesive

= **0.604m ****× 0.204m ****× 0.2m.**

=**0.02464 CUM.**

**1. The number of AAC blocks required**

= volume of the wall ÷ volume of the block with adhesive

= 6 CUM. ÷ 0.02464 CUM.

=**243.50 nos.**

**The volume of adhesive required **

= volume of the block wall - the volume of the total no. of AAC blocks

= [volume of the block wall - ( no. of blocks × vol. of a single block.)]

= [6 CUM. - (243.5 nos. × 0.024 CUM.)]

= [6 CUM. - 5.844 CUM.]

=**0.156 CUM.**

The **40** kg of adhesive bag covers **6 to 8** sqm. wall area in **4mm**. joint thickness. This coverage area is considered for the **200mm**. thick AAC block wall.

Let us consider the average cover area of **7 sqm.** for **1** adhesive bag.

**The area of the block wall**

= length × height

= 10m. × 3m.

= **30 sqm**.

**The no. of adhesive bags (40kg.) required**

= [total area of block wall ÷ area covered by 1 bag]

= [30 sqm. ÷ 7 sqm.]

= **4.28 bags**.

**Let us now find out the materials required for 1 CUM. & 1 cu ft. of an AAC block wall.**

__1. AAC blocks:__

__Blocks required for 1 CUM. of AAC block wall__

For 6 CUM of block wall **ðŸ‘‰** 243.5 nos. of AAC block.

So, for 1 CUM of block wall **ðŸ‘‰** _ nos. of AAC block?.

=[ 1 CUM × 243.5 nos. ÷ 6 CUM.]

= **40.58 nos**.

__Blocks required for 1 cu ft. of wall__

= 40.58 nos. ÷ 35.315

( As 1CUM = 35.315 cu ft.)

= **1.149 nos.**

__2. Adhesive:__

__Adhesive required for 1 CUM. of AAC block wall__

=[ 1 CUM × 4.28 bags. ÷ 6 CUM.]

= **0.713 bags**

__Adhesive required for 1 cu ft. of block wall__

= [0.713 bags ÷ 35.315]

= **0.021 bags.**

**Continued. ðŸ‘‰ The material**** calculation for AAC block wall construction with cement mortar.**
