Autoclaved Aerated Concrete (ACC)

Autoclaved Aerated Concrete (ACC) is a thermally insulated concrete based material. It is used in both internal and external construction. This is relatively a new product that is being integrated into the construction process.

Advantages and Disadvantages of Autoclaved Aerated Concrete

Autoclaved aerated concrete is quick and easy to install mainly because the material can be sanded, routed or cut to size at the construction site using just standard carbon steel power tools. When autoclaved aerated concrete is used, it can be covered with siding such as brick or vinyl or even stucco to keep the elemnets away from it.

There are many advantages and disavantages of autoclaved aerated concrete that are listed below.

advantages of autoclaved aerated concrete are listed below.

1. Environmentally Friendly: When used, it helps to reduce at least 30% of environmental waste as opposed to going with tradtional concrete. There is a decrease of 50% of green house gas emissions. When possible, using autoclaved aerated concrete is a better choice for the environment.

2. Energy Saver: It is an excellent property that makes it an excellent insulator and that means the interior environment is easier to maintain. When it is used, there is usually not a need for any supplementary insulation.

3. Great Acoustics: When you think of concrete, you do not consider it to be excellent for acoustics, however autoclaved aerated concrete has excellent acoustic performance. It is able to be used as a very effective sound barrier.

4. Fire Resistant: Just like with regular concrete, ACC is fire resistant. This material is completely inorganic and not combustible. 

5. Great Ventilation: This material is very airy and allows for the diffusion of wanter. This will reduce the humidity within the building. ACC will absorb moisture and release humidity; this helps to prevent condensation and other problems that are related to mildew.

6. Non-Toxic: There are no toxic gases or other toxic substances in autoclaved aerated concrete. It does not attract rodents or other pests nor can it be damaged by such.

7. Lightweight: Concrete blocks that are made out of ACC weigh about one-fifth of typical concrete. They are also produced in sizes that are easy to handle for quick construction.

8. Accuraacy: The panels and blocks made of autoclaved aerated concrete are produced to the exact sizes needed before they even leave the factory. There is less need for on-site trimming. Since the blocks and panels fit so well together, there is a reduced use of finishing materials such as mortar.

9. Long Lasting: The life of this material is extended because if is not affected by harsh climates or extreme changes in weather conditions. It will not degrade under normal climated changes either.

10. Quick Assembly: Since it is a lightweight material and easy to work with, the assembly is much quicher and smoother. This increases production time when on-site.

Disadvantages of Autoclaved aerated concrete

The major disadvantages of autoclaved aerated concrete are listed below.

1. The production cost per unit for ACC is higher than other ordinary concrete.

2. Number of manufacturer is limited. So, cost will drastically increase in places far from the manufacturer and need to travel a long distance.

3.It is not as strong as conventional concrete.

4. Very few contractors who are familiar with autoclaved aerated concrete.

5. Construction with autoclaved aerated concrete may will need special permission.
