About us
Founded in 2021, AAC Blocks Bihar is committed to revolutionizing construction in Bihar and Jharkhand with modern, eco-friendly building solutions. The history of Autoclaved Aerated Concrete (AAC) blocks dates back to 1924 in Sweden, when architect Dr. Johan Axel Eriksson developed this lightweight, durable, and energy-efficient alternative to traditional red bricks. Over the years, AAC blocks have gained popularity worldwide, including in India, due to their fire resistance, thermal insulation, and cost-effectiveness.
In Bihar and Jharkhand, where construction is rapidly evolving, the demand for stronger, lighter, and more sustainable materials is at an all-time high. AAC Blocks Bihar is bridging this gap by providing high-quality AAC blocks that not only reduce construction costs but also ensure faster and more durable building solutions. Our mission is to support the region’s builders, contractors, and homeowners with materials that are stronger, greener, and built for the future.
