Autoclaved Aerated Concrete AAC)(

History of AAC?

The Autoclaved Aerated Concrete (AAC) material was developed in 1932 in Sweden. It has become one of the most used building materials in Europe and is rapidly growing in many other countries around the world.

Autoclaved Aerated Concrete is a lightweight, load-bearing, high-insulating, durable building product, which is produced in a wide range of sizes and strength.

AAC offers incredible opportunities to increase building quality and at the same time reduces costs at the construction site. AAC is produced out of a mix of pulverized fly ash (PFA), lime, cement, gypsum, water and aluminium and is hardened by steam-curing in autoclaves. As a result of its excellent properties, AAC is used in many building constructions, for example in residential homes, commercial, industrial buildings, schools, hospitals, hotels and many other applications. The construction material AAC contains 60% to 80% air pores.

About Us

Green Mirror Buildcon Pvt. Ltd. is an endeavor towards building an eco-conscious society where nature and future can grow harmoniously. Modern day construction practices take many points in to consideration. While aesthetic and strength are the prime factors, products are also judged on the attributes such as safety, cost-effectiveness, eco-friendliness and workability.

These many attributes propelled us to present Grey Brick Autoclaved Aerated Concrete Blocks- An ecofriendly, cost-effective and safe brick solution which preserves the harmony of the nature and saves your project form heavy construction cost. Truly it proves to be a solid option to traditional clay brick.

Our plant located at Kheda, Gujarat. We at Green Mirror Buildcon Pvt. Ltd. are poised to revolutionize and transform the conventional construction practices with innovative and effective Grey Brick AAC Blocks.
