New Delhi [India] July 16 (ANI/PNN): Technology has changed the way we think, work and live. It incites a new approach to introduce new, better and innovative solutions, ready for the future.
One of these products is autoclaved aerated concrete blocks – AAC blocks. Over the past decade, this green, non-toxic building construction material has become a preferred choice over red bricks due to its unique combination and superior building properties like strength, low weight, thermal insulation, sound absorption and unparalleled and economical fire resistance. With its unparalleled construction ability, it has established itself as the future of building construction.
Opportunity in India
India is the second largest block manufacturer in the world after China. The Indian block industry is almost entirely unorganized, characterized by many small players competing regionally, having around 150-180 factories for AAC block.
Despite the strong growth of AAC block in building applications over the past decade, it only accounts for 7-8% of the industry, while 85-90% of the industry is still dominated by red bricks, which means huge potential in the years. come.
The global autoclaved aerated concrete (AAC) market size is expected to reach USD 28.41 billion at a stable CAGR of 5.3% in 2028, according to the latest analysis from Emergen Research. According to a recent report, the Indian AAC block market is expected to register a CAGR of 14.3% during the period 2020-27 to reach Rs 11,000 crore.
AAC block manufacturing is gaining prominence in the Indian market and a large number of factories are being set up across the country, especially in western India.
A large number of integrated townships, mass housing (for urban poor, slum upgrading, etc.), IT/ITES parks, high-rise buildings and SEZs are commonly seen these days with the AAC block, and the growth of the segment will only increase exponentially. in the years to come.
“The Indian market is accepting AAC blocks well. Its use will increase dramatically in the coming years due to the increased awareness among builders and architects of the many beneficial attributes of AAC blocks over red clay and fly ash bricks. Urban labor shortages and high interest rates forced developers and construction companies to seek faster and more efficient building materials.
In addition to its adherent benefits, projects built using the AAC block complement project management in terms of speed, consistency and quality of construction. In the domestic market, key factors such as pent-up demand and the Indian government’s push through numerous infrastructure and housing projects and regulations to use eco-friendly building materials as part of its mission of zero carbon emissions are key factors driving the AAC market growth,” said Mohit Saboo, Director and Chief Financial Officer, BigBloc Construction Ltd.
BigBloc is the only listed company in the AAC Block Space in India and the largest in Western India. In the coming times, the company plans to launch products such as ALC panels, tile adhesives, gypsum plaster and other construction chemicals. The company has a vision to become the largest manufacturer of AAC blocks and panels in India within the next 2-3 years.
With the increase in regional government projects and the expansion of the real estate sector, the demand for autoclaved aerated concrete is expected to see an increase. The Government of India’s “Housing for All by 2024” is a major shift for the industry, as are projects such as Pradhan Mantri Awas Yojana, Police Housing, Kanya Shiksha Parishar, etc., where the government has made housing mandatory. using AAC blocks. .
India is expected to witness an investment of around $1.3 trillion in housing over the next seven years, during which it is expected to witness the construction of around 60 million new homes. The union cabinet also extended the validity of the PMAY-Gramin scheme until March 31, 2024, to meet the house building target of 2.95 crore.
Green Solutions to Growing Urbanization
Growth in the infrastructure sector, growing preferences for low-cost homes, and increasing emphasis on green and soundproof buildings are driving the CAA market. Due to their energy efficient properties, in addition to being fire, termite or pest resistant, earthquake resistant, lightweight, durable, quick and easy to apply, AAC blocks have become a preferred choice.
The construction industry, for a very long time, used red clay bricks. The fundamental problem, however, is that he used red earth for mass production, which is cultivable land that reduces the forest area.
AAC is a natural, non-toxic building material that saves energy and is environmentally friendly. In addition, the thermal insulation properties of AAC blocks reduce energy consumption and help combat global warming, resulting in savings throughout the life of the building.
“We are the only company in this segment that generates carbon credits,” Mr. Mohit Saboo said.
“The growing carbon footprint on the environment is a growing concern. The company is committed to producing green building products and solutions, and the ultimate goal of helping the construction and infrastructure industry build green and sustainable habitats has been the company’s vision. . With the vision of conserving soil – NXTBLOC, a green product for industry, was launched by the company,” he added.
The carbon footprint of NXTBLOC AAC blocks is significantly lower than traditional wall materials (carbon levels per square foot: AAC blocks 2.13 kg CO2, clay bricks 17.6 kg CO2, concrete walls 14 kg of CO2). In addition, the light weight of NXTBLOC AAC blocks reduces carbon emissions as more cubic meters can be transported per truck compared to traditional wall material (3 trucks of traditional cu m material equals 1 truck of AAC blocks cu m ).
AAC block manufacturing process
Economy and faster execution also drive growth
AAC blocks help to build the house better, faster and cheaper through the use of innovative construction technologies and have become a choice of building material and a suitable replacement for clay bricks.
Pricing of raw materials – lime, cement, petroleum coke and aluminum powder also currently favor AAC blocks over clay bricks.
Fly ash is one of the main raw materials for AAC blocks. In India, many thermal power plants generate a lot of coal waste (fly ash); AAC blocks use it as a raw material and provide a green solution to the Indian brick industry. Additionally, over the past decade, the prices of bricks have increased significantly over AAC blocks, giving it an additional competitive advantage over bricks. Prices for AAC blocks are around Rs 4,000 per cubic meter, while brick prices have exceeded Rs 5,500 per cubic meter.
