Autoclaved Aerated Concrete (AAC) Block Plant – An Emerging Green Building Material

Autoclaved Aerated Concrete (AAC) Block Plant is a newly-adopted and emerging green building material. It has been used as a substitute of the conventional red clay bricks mainly for commercial, residential and industrial construction activities. AAC Block Plants have been used globally and they are extensively used in Europe, India, Asia, USA and other countries.

Autoclaved Aerated Concrete plant is a light weight precast building material that provides both construction economy and speed. Large Scale AAC Plantsare environment friendly products as they are manufactured using 60-65% of fly ash, an inevitable waste from lignite-based thermal power plants or coal. As these plants have many desirable attributes, AAC block plants are gaining popularity and they have been used as a replacement of the traditional fired clay brick.

AAC Industry structure and development

Construction industry is one of the most important sectors of the economy as it motivates building infrastructure and creates enlargement opportunities for other sectors in the economy. On the other hand, it contributes around 8% in GDP and registered an annual growth of 4.8% during 2015-2016.

However, economic growth and demand for building materials usually move in tandem. The building material like AAC block plantshas recorded considerable growth over the last few years. Moreover, improving economic growth, expanding population along with quick increase in per capital income, industrialization and urbanization signals good growth prospects for this sector

AAC block: an emerging green building material in India

AAC block, which is also known as autoclaved cellular concrete or autoclaved lightweight concrete or aerated brick, is an eco-friendly building material used in construction activities.

They offer a unique combination of strength, low weight, cost-effectiveness and durability compared with a clay brick. Other AAC products include wall panels, floor and roof panels and lintels.

Salient features of AAC block plants:

The following are the salient features of AAC block that make it user-friendly product over other construction materials:

Environment friendly

With the help of fly ash, AAC helps to create a sustainable environment by reducing CO2 emissions, water pollution and agricultural soil erosion.

Light Weight

AAC block plantsare easier and cheaper to transport. Lighter block makes construction easier and faster.

Cost Saving

AAC’s light weight saves on labor cost.

Easy workability

They are available in custom sizes.  Block can be easily cut or drilled to fit individual requirements. Accurate cutting minimizes the generation of solid waste during use.
