Affordable Housing, Emergent India

AAC Block- its advantages

AAC Block- its advantagesThe pursuit of ‘green’ buildings that will preserve the environment may possibly veer off in an unpredictable direction that will change the face of India’s housing. Contradictory though it may sound, concrete is raising its head as an attractive and eco-friendly alternative for residential housing. AAC block provide a much better better alternative than clack bricks. They are much light in weight yet have stringer compressive strength.

Although concrete has been used in European homes for over fifty years, it’s not as popular here in India. If the thought of gray concrete homes in India is abhorrent to you – think again.

Among the European countries that make the largest proportion of concrete houses, France is at top. Yes, that includes those cute little homes in the villages of French Province that people drive for miles to see! Underneath the sunny yellow paint on the exterior ‘stone’ finish walls is the very ugly gray concrete. Under the brilliant blue shutters framing the tiny windows is again blah gray concrete.

What’s more, inside the cool cottages where the interior walls are painted in cream and edged with dark woodwork for relief is also blah gray concrete! So where’s the problem?

AAC Block – Autoclaved Aerated Concrete

Change is always resisted by people, but concrete is gaining ground in developments around India. This is becauseAAC Block- its advantages concrete has re-invented itself into the environmentally acceptable AAC. It is also known as E-Crete, but AAC block- short for Autoclaved Aerated Concrete block – can produce a home that is way more fireproof and whose construction is 80% air!

Mice and Termites resistance

Buildings made from AAC block will not rust, decompose, warp or rot and this makes them very low at maintenance. Concrete does not offer the type of atmosphere that encourages little critters such as termites; it also cannot be chewed through by mice etc, which are two more points in its favor.


AAC Block- its advantagesConcrete walls do not give off toxic gasses and neither will home owners experience ‘cold spots’ in their rooms. This can be attributed to the unique design of the blocks which means that an AAC block home comes with its own insulation against both the summer heat and the winter cold.

Sound Proof

AAC offers better acoustics than a normal wooden home, in that it reduces the traveling of sounds such as mechanical noises, decreases the penetrating ability of outside noises and does away with the echoing sound of an empty room. Or, in a nutshell, it is a quieter life inside!

For those who are interested in the environmental ethics of it all – AAC block is made from adding a naturally occurring expansion agent to natural cement and sand which produces air bubbles within – rather like making concrete bread! It means all the trees can stay in the forest.
