However, with the introduction of autoclaved aerated concrete in 2022, the sector has begun to witness a transformative shift toward sustainability. Rancon, as an early adopter and advocate for AAC, has played a pivotal role in accelerating its acceptance in Bangladesh.The Evolution of AAC AdoptionWhen AAC was first introduced, awareness was minimal, and the industry was hesitant to shift from conventional materials. Traditional bricks, fired using coal and derived from valuable topsoil, were the standard, despite their severe environmental repercussions. Recognizing the urgency for change, Rancon eliminated topsoil-based, coal-fired bricks from projects, focusing instead on integrating AAC as a primary building material.As pioneers in AAC adoption, Rancon actively engaged with industry professionals, highlighting its advantages, including environmental benefits, energy efficiency, and superior structural properties. Over time, as the demand for sustainable construction practices grew, AAC gained widespread acceptance. Today, multiple local manufacturers have entered the market, ensuring a steady supply and more competitive pricing, further supporting its large-scale adoption.Typical application of AAC blocks in Bangladesh
