Narayan Saboo, Chairman, Bigbloc Construction, discusses the qualities of AAC blocks and its environmentally friendly properties.

What is the composition of Autoclaved Aerated Concrete (AAC) blocks?
AAC is a lightweight, precast, cellular concrete. It is a green building material composed of fly ash, gypsum, lime, portland cement, water and aluminum powder. AAC blocks are made in rectangular prism shape only.

What is the core functionality of the blocks?
AAC blocks are widely used in the construction of apartments and other types of residential properties, industrial and commercial buildings. Owing to their excellent heat insulation capacity and thermal resistance, AAC blocks find application in interior and exterior construction.

What brings strength and durability to these blocks?
These materials include cement, lime, fly ash, gypsum, aluminum powder and some other additives. The precise combination and proportion of these materials contribute to their overall strength.

How do you ensure quality standards?
We make AAC blocks as per BIS code IS 2185 Part 3, guidelines in IS code to ensure quality standards.

What are the key advantages of using these blocks as building materials?
AAC blocks are eco-friendly and sustainable. They are lightweight, thermally insulated, energy efficient and fire resistant. Their other qualities include acoustics performance, easy workability, design flexibility and faster construction. AAC Blocks are one-third in weight as compared to red bricks thereby reducing the dead load on the building and resulting in huge saving of structural costs. Also, as the size is equivalent to almost nine red bricks, construction is much faster; the labour required is less; joints in the wall are also less thereby resulting in mortar savings, too.

How does it impact the environment?
AAC blocks are eco-friendly and sustainable. They are green lightweight building materials, with less transport cost. This material warms the room during the winter and cools it during the summer, reducing air-conditioning system usage by at least 25 per cent. Non-toxic and pest repellent, they prevent soil erosion and consume less water. Use of red bricks results in an upper layer of soil erosion, which makes the land barren or infertile in the long run.

What innovations can we expect from you?
We are starting with the manufacturing of ALC panels, which is further advancement of technology as ALC panels are a new age building material that is a further advancement of AAC Blocks.
Panels are reinforced with steel and they will make construction much faster, too. Also, we are looking to get many other new age building materials in our partnership with SCG.

JSW Cement has commissioned an additional 1 MTPA cement grinding unit in Nagaur, Rajasthan, taking the company’s total cement grinding capacity to 25.1 MTPA. The commissioning was announced on Tuesday, October 6.

The company said the new unit had increased the total cement grinding capacity at its Rajasthan plant to 3.50 MTPA. The expansion adds to JSW Cement’s production infrastructure as it continues to build capacity across its operating network.

The company’s total clinker manufacturing capacity, including capacity at its joint venture JSW Cement FZC, stands at 9.74 MTPA. Clinker is an intermediate material used in cement production, and its availability supports the company’s grinding operations.

JSW Cement is also pursuing a proposed merger of its listed subsidiary Shiva Cement with the company. The scheme, approved by the boards of the respective companies, involves issuing five fully paid-up JSW Cement equity shares for every 41 shares held by Shiva Cement shareholders other than JSW Cement.

The arrangement remains subject to shareholder and regulatory approvals. JSW Cement currently holds 66.23 per cent of Shiva Cement’s paid-up equity share capital, and the shares held by JSW Cement in the subsidiary will be cancelled under the proposal without any issue of JSW Cement shares against that holding.

The scheme has an appointed date of April 1, 2026, and the company has indicated that completion could take 12 to 14 months, depending on the receipt of approvals. These include clearances from stock exchanges, the Securities and Exchange Board of India, the National Company Law Tribunal and other applicable authorities, along with approvals from shareholders and creditors where required. JSW Cement shares closed at Rs. 113.15 on the BSE, up Rs. 2.05, or 1.85 per cent.
