**How many AAC blocks in 1 square metre ?**Full form of **AAC** is Autoclaved aerated concrete. It is a lightweight, precast, foam concrete building material suitable for producing concrete masonry unit **(CMU)** like blocks. It is composed of quartz sand, calcined gypsum, lime, cement, water and aluminum powder, AAC products are cured under heat and pressure in an **autoclave**.

In this article we know about how many AAC blocks in 1 square metre. And there is various good properties of AAC blocks are following: AAC blocks provide greater insulation against sound out loud noises and providing good insulation.

AAC Block are light weight and durable and can withstand extreme earthquake condition. AAC blocks are easier to use in the construction process and save time as well as money for contractor and owner like. Due to presence of air in mixture AAC blocks and light, yet strong due to the process through which they are created.

AC blocks made in uniformly and can be cut and shaped according to required in construction. it provide greater insulation against heat since they do are not good conductor of heat. The technology used in creating AAC blocks ensure that is blocks are resistant to fire.

**What are size and specification of ACC blocks**

Regular size of ACC block is 600 mm × 200 mm × 100 mm, we know it cut in Desire shape and size so various size of AAC blocks available in construction work and needed construction, standard size of AAC block are following:-

1) 600 mm × 200 mm × 075 mm or 24″ × 8″ × 3″ ( length × height × width )

2) 600 mm × 200 mm × 100 mm or 24″ × 8″ × 4″ ( length × height × width )

3) 600 mm × 200 mm × 125 mm or 24″ × 8″ × 5″ ( length × height × width )

4) 600 mm × 200 mm × 150 mm or 24″ × 8″ × 6″ ( length × height × width )

5) 600 mm × 200 mm × 175 mm or 24″ × 8″ × 7″ ( length × height × width )

6) 600 mm × 200 mm × 200 mm or 24″ × 8″ × 8″ ( length × height × width )

7) 600 mm × 200 mm × 225 mm or 24″ × 8″ × 9″ ( length × height × width )

8) 600 mm × 200 mm × 250 mm or 24″ × 8″ × 10″ ( length × height × width )

9) 600 mm × 200 mm × 275 mm or 24″ × 8″ × 11″ ( length × height × width )

10) 600 mm × 200 mm × 300 mm or 24″ × 8″ × 12″ ( length × height × width )

Some other size of AAC block also used in construction line rather than that standard size, but this article only mention standard size of AAC blocks and how many number of block in 1 square metre ? Containing different size.

**How many AAC blocks in 1 square metre ?**

In 1 square metre there are **9 pieces** of AAC blocks measuring 600 × 200 × 75 mm. To calculate the number of AAC blocks, divide the wall area by the area of one AAC block. One block is 600mm × 200mm = 120,000 / 1000,000 = 0.12 square meters. Then the number of AAC blocks per square metre = 1/0.12 = 8.34, nearly 9 pieces.

Number of AAC blocks calculated by dividing 1 square metre by area of 1 AAC Block.

Number of acc blocks = given area/ 1 block area

No. of blocks = 1 square meter/ 1 block area

**Q1) how many AAC blocks in 1 square metre of size 600 mm × 200 mm × 075 mm block**

● Given: size of block = 600 mm × 200 mm × 075 mm

Given area = 1 square meter

Number of blocks = ?

● Solve: number of AAC block calculated by dividing 1 square metre by area of 1 AAC Block.

No. of blocks = 1 square meter/ 1 block area

(L × H × B) of block = 600 mm × 200 mm × 075 mm

Converting into meter we get

(L × H × B) of block = 0.600 m × 0.200 m × 0.075 m

Area of 1 block = length × height

Area of 1 block = 0.6 m × 0.2 m = 0.12 m2

No. of blocks = 1 m2/0.12 m2 = 8.33 nos

9 number of AAC Block present in 1 square metre of size 600 mm × 200 mm × 075 mm ( length × height × width ).

**Conclusions:**

In one square metre there are **9 pieces** of **AAC blocks** measuring **600 × 200 × 75 mm**. To calculate the number of AAC blocks, divide the wall area by the area of one AAC block. One block is 600mm × 200mm = 120,000 / 1000,000 = 0.12 square meters. Then the number of AAC blocks per square metre = 1/0.12 = 8.34, nearly 9 pieces.
