# All About AAC blocks in 1 square metre

AAC blocks, or Autoclaved Aerated Concrete blocks, have gained immense popularity in the construction industry in recent years. Their lightweight, high strength, and eco-friendly properties make them a preferred choice for building materials. But what sets them apart from other construction materials is their efficiency – with just 1 square meter of AAC blocks, one can build an entire structure. In this article, we will delve deeper into the world of AAC blocks and explore everything there is to know about their features, benefits, and applications in construction. So, let’s dive in and discover all about AAC blocks in just one square meter.

## How many AAC blocks in 1 square metre ?

AAC (Autoclaved Aerated Concrete) blocks are a type of lightweight and eco-friendly building material used in construction. They are made by mixing cement, lime, fly ash, water, and an expanding agent, which is usually aluminum powder.

The commonly used size of AAC blocks is 600 mm x 200 mm x 100 mm, which is equal to 0.012 square meters. However, there are variations in sizes available in the market, such as 600 mm x 200 mm x 150 mm, 600 mm x 200 mm x 200 mm, and 600 mm x 200 mm x 300 mm.

Considering the commonly used size, 600 mm x 200 mm x 100 mm, in 1 square meter area, there are approximately 83 blocks. This estimation may vary depending on the wall thickness or size of the blocks used.

To explain it better, let’s calculate the number of blocks required for a wall of 10 meters length and 3 meters height using 600 mm x 200 mm x 100 mm size blocks.

Area of the wall = 10 meters x 3 meters = 30 square meters
Size of AAC block = 600 mm x 200 mm x 100 mm = 0.012 square meters
Number of blocks required = 30 square meters / 0.012 square meters = 2500 blocks

Therefore, for a wall of 10 meters length and 3 meters height, approximately 2500 AAC blocks of size 600 mm x 200 mm x 100 mm are required.

Apart from the size and thickness of the blocks, the number of blocks also depends on the type of wall being constructed. Different types of walls like solid walls, cavity walls, and partition walls require different quantities of AAC blocks.

In conclusion, the number of AAC blocks required in 1 square meter area depends on various factors like the size and thickness of the blocks, type of wall, and design of the structure. It is best to consult a professional to calculate the exact number of blocks required for a specific project.

## What are size and specification of ACC blocks

ACC (Autoclaved Aerated Concrete) blocks are lightweight, precast building materials that are used for constructing walls, partitions, and panels. These blocks are made from a mixture of cement, lime, sand, water, and small amounts of aluminum powder, which creates microscopic air bubbles within the concrete mix. The air bubbles give the blocks a cellular structure, making them lightweight and highly durable.

Size:
The standard size of ACC blocks is 625mm x 250mm x 100mm (length x width x height). However, these blocks also come in different sizes such as 625mm x 300mm x 100mm and 625mm x 200mm x 100mm, to cater to specific construction requirements.

Specification:
1. Compressive Strength:
The compressive strength of ACC blocks varies from 3-4 N/mm² to 7-8 N/mm², depending on the grade and density of the blocks. This makes them strong and stable, capable of withstanding heavy loads and forces.

2. Fire Resistance:
ACC blocks have a high fire resistance rating of up to 4 hours, making them a suitable choice for fire walls and fireproof constructions. The high content of air bubbles acts as an insulator, reducing the spread of fire.

3. Thermal Conductivity:
The thermal conductivity of ACC blocks ranges from 0.16 to 0.24 W/mK, making them energy-efficient. These blocks provide excellent insulation and help in maintaining a stable temperature inside the building.

4. Sound Insulation:
The cellular structure of ACC blocks makes them excellent sound insulators, reducing the transmission of noise through walls, floors, and ceilings. This makes them suitable for buildings located in noisy surroundings.

5. Water Absorption:
The water absorption of ACC blocks is generally less than 10%, making them highly water-resistant. This prevents the blocks from getting damaged due to moisture, and also prevents the growth of mold and fungi.

6. Density:
The density of ACC blocks ranges from 500 to 800 kg/m³, making them lightweight and easy to handle. This also helps in reducing the overall weight of the building, making it suitable for construction in areas with poor soil conditions.

7. Eco-Friendly:
ACC blocks are made from natural materials, making them environmentally friendly. The production process of these blocks also results in minimal greenhouse gas emissions.

In conclusion, ACC blocks are an excellent construction material due to their lightweight, high strength, fire resistance, thermal and acoustic insulation properties, and eco-friendliness. Their standardized size and specifications make them a preferred choice for various construction projects, providing a cost-effective and sustainable solution.
