ACC cement blocks are replacing traditional bricks at a rapid speed. These have foam-looking porous textures and are lightweight. Some basic materials used for crafting them are lime, sand, water, and cement. This block is particularly preferred for large-scale projects and is widely installed in civil and industrial construction. Builders primarily use these for floors, roofs, and walls.
What are ACC Cement Blocks?
Autoclaved Aerated Concrete (AAC) blocks are an eco-friendly and green building material. These are load-bearing, lightweight, and highly insulating. The ACC cement building blocks are highly durable and three times lighter compared to traditional red bricks.
ACC Cement Blocks: Uses
ACC cement block is widely used in several construction projects. Some of its major uses include:
- The use of ACC concrete blocks is reasonable and economical in high-rise frame buildings. Builders widely use these blocks to construct external and internal walls.
- ACC are lightweight, making them highly suitable for earthquake-resistant areas. Compared with traditional concrete bricks, these are highly durable and earthquake-resistant up to a certain limit, enhancing the safety of individuals.
- Due to their excellent thermal insulation performance, builders prefer them for constructing buildings in cold areas.
- These are mostly used for ceilings, roofs, and floors.
ACC Cement Blocks: Importance
The key reasons why these cement bricks are highly preferred by builders and engineers are listed below:
Sustainability
Using recycled industrial waste, zero gas emissions, non-toxic ingredients, and minimum energy consumption makes them sustainable and eco-friendly.
Lightweight
Compared to traditional red bricks, these are three times lighter. This reduces the dead load of the building, allowing the construction of taller buildings.
Energy Efficient & Thermal Insulation
The tiny air pores and thermal mass of these materials provide excellent thermal insulation, reducing the air conditioning and heating costs of a building.
Acoustic Performance
These are porous and offer sound absorption. They provide sound attenuation of around 42 dB, blocking major disturbances and making them ideal for hospitals, offices, schools, hotels, and other structures needing acoustic insulation.
Fire Resistant
These materials are fire-resistant and noncombustible up to 1600°C, withstanding direct exposure for up to 6 hours.
Seismic Resistant
These lightweight blocks minimize structure mass, reducing the impact of earthquakes on buildings. Their noncombustible nature also offers fire resistance benefits.
Design Flexibility
These materials exhibit high flexibility, allowing customization into any shape or design. Users can easily drill, nail, cut, and shape these blocks to meet specific requirements.
Quick Construction
Using these materials in construction decreases the time by around 20%. Multiple block sizes reduce the number of joints in masonry walls, while the lightweight nature facilitates quicker and easier placement and transportation.
ACC v/s CLC: Key Differences
To learn some of the major differences between ACC and CLC, refer to the table given below:
| Factor | ACC | CLC |
| Production Capacity | The production capacity of ACC is higher and can also be increased as per the customer’s requirements. | The production capacity of the CLC is lower than that of ACC. |
| Raw Materials | Lime, cement, gypsum, aluminium powder, fly ash and water are combined to create ACC. | To create a CLC block, pre-formed stable foam and cement fly-ash slurry are mixed together. |
| Scalability | By installing varying autoclaves and moulds, the production of ACC can be increased further. Hence, the production of these can be increased with lesser investment. | Increasing the production of CLC are quite challenging, with the same setting as each piece of equipment that comes with small capacities. |
| Compressive Strength | The compressive strength of these materials is 3.5-7N/mm², which is comparatively superior to other lightweight blocks. Moreover, they are 25% stronger than other products with similar density. | However, these materials hold a compressive strength of 3N/mm², which is lesser than other lightweight blocks. |
| End Product Quality | ACC are manufactured by implementing the latest technology in factories. This is why their end product quality is good and consistent. | The end product quality of CLC entirely depends on the kind of foam used in manufacturing and the degree of quality control. |
