made from locally available materials, are less resource-intensive and
also give better thermo-physical properties, compared to conventional
materials. There is also impetus to developing AAC bricks and RC
bricks through Fly Ash technology. The private sector has also been
playing an active role in developing indigenous technologies. A few
emerging technologies recommended by the Building Materials and
Technology Promotion Council (BMTPC) for further exploration to
ensure better quality products are listed below:
• Fly ash-based bricks, RCC blocks, cellular light weight concrete,

bamboo-based materials, bagasse boards
• Partial pre-fabrication technology along with easy to operate

machines for deployment
• Monolithic concrete technology using plastic/aluminium composite

formwork
• Rapidwall construction system
