**What is unit weight of 1 AAC Block and how we calculate,****Full form of ACC block 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.

In this article we know about what is unit weight of 1 AAC Block and how we calculate, when we talk about weight of AAC Block, it is calculated by multiplying density (kg/m3) and volume (m3) of block. the regular size of AAC block is 600 mm × 200 mm × 100 mm and their volume is calculated 0.012 m3 and density 600 kg/m3, than weight of 1 acc block is 0.012 m3 × 600 kg/m3 is equal to 7.2 Kg.

Autoclaved Aerated Concrete is an eco- friendly and certified green building material which is lightweight, load-bearing, high- insulating.

**Meaning of AAC block** is its products are cured under heat and pressure in an autoclave and there is presence of air in the mixture of ACC block and hard bearing good compressive strength like concrete that why it name is AAC block ( autoclaved aerated concrete).

And compressive strength of ACC block is about 3 to 4.5 N/mm2 and their normal dry density or unit weight is approx 550 – 650 Kg/m3 and wet density or unit weight is 800 Kg/m3.

**unit weight of ACC block** in wet condition is 800 Kg present in 1 cubic meter and in dry condition approx 600 kg present in 1 cubic meter.

**How to calculate Unit Weight of 1 AAC Block ?**

Weight of 1 aac block = Volume × density

Dry density of aac block = 600 Kg/m3

Wet density = 800 Kg / m3

And volume of AAC block is calculated by multiplying all three dimension length height and width.

Volume of aac block = (L × H × B)
