Advantages of AAC blocks

Advantages of AAC blocks

Advantages of AAC blocks are varied and many depending upon local conditions. Some of those advantages from India’s point of view are mentioned below:

Lightweight
AAC blocks are about 50% lighter than clay bricks of equivalent size. This translates into less dead weight of a building and allows entire structure to be lighter therefore reducing amount of steel and concrete used in structural components like beams, columns and roof/floor slabs.

Easy Workability
AAC blocks are very easy to work with and can be cut accurately reducing the amount of waste generated.

Single Product Solution
Buildings constructed with AAC blocks do not require separate insulation products reducing construction cost, energy footprint and environmental impact of buildings.

Environmental Impact
Manufacturing of AAC blocks and panels does not consume high amount of energy. Moreover since AAC  blocks are light weight, it saves energy required for transportation and leads to reduced CO2 emissions by transport vehicles. Since AAC blocks are made from fly ash – an industrial waste product – generated by thermal power plants, it offers a low cost and sustainable solution for today and tomorrow. AAC blocks are a requisite for green buildings.

Easy Transportation
It is easy to transport AAC blocks as it does not suffer from high transit breakage usually associated with clay bricks.

Longevity
AAC blocks do not lose strength or deteriorate over time. Buildings constructed with AAC blocks do not require routine repairs that are required for buildings using clay bricks.

Thermal Insulation
AAC blocks and panels offer excellent thermal insulation. This reduces recurring cost of energy required for heating and cooling. Better thermal insulation also allows usage of smaller HVAC than required conventionally.

Shorter Project Duration
Buildings can be built with AAC blocks 50% faster compared to clay bricks. This translates to lower project completion times benefiting project developers.

Fire Resistance
Due to high fire resistance offered by AAC blocks, structures made from AAC blocks have higher rate of survivability in case of fire.

Sound Insulation
Sound absorption properties of AAC makes it ideal material for reducing ambient noise. AAC blocks are well-suited for establishments like hospitals and offices situated in noisy areas.

High Survivability
Millions of air pockets in AAC blocks cushion structure from major force and prevents progressive collapse of a building. AAC structures are known to maintain structural integrity despite of seismic activity (earthquakes), heavy rains, extremely low temperature and salty air.

Contribution to Nation
AAC factories create many jobs directly and indirectly creating a social impact. Along with that they pay Excise Duty and VAT contributing to national economy.

Advantages of AAC blocks lead to faster and cost-effective construction

Hi
I want to know how and what is the mix ratio of aac and clc blocks
I’m just starting to product a light weight blocks
And from where I can get the materials to do aac and clc blocks ? It may be around me but I don’t know it !
Is their any factory gives training in aac or clc ?
Please I need any help

Many thanks

    Dear Hamad,

    Thank you for your response on my website. I’ll need some information before I can help you.

    1. What is your location?
    2. What kind of light weight blocks are you producing?
    3. Are you aware of difference between AAC blocks and CLC blocks?
    4. Are you aware of equipment/finance required to set up AAC blocks or CLC blocks project?

    Answers to these questions will help me guide you.

    As far as training is concerned, I don’t think any factory offers that sort of training

    Dear Maninder,

    Thank you for your response on my website. That is a very good question and deserves a separate article to answer it. I am working on a similar article and will post it soon, keep watching this space. To give you a rough idea about suitability of AAC blocks vs hollow concrete blocks, I can say that savings in overall project cost is around 23% in favour of hollow concrete blocks. This figure is over and above the price difference based on a case study done for Bangalore area. In areas where cost difference between AAC blocks and hollow concrete blocks is smaller, savings in overall project cost would be much higher.
