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.

The additional capacity will cater to cement demand across Rajasthan, Haryana, Punjab and the National Capital Region (NCR). The expansion has been funded through a combination of equity and long-term debt.
During the quarter ended September 30, 2026, JSW Cement also commissioned an Alternate Fuel Handling System and a Waste Heat Recovery System (WHRS) at the Nagaur plant.

The Boards of Directors of JSW Cement and its listed subsidiary Shiva Cement have approved a scheme of arrangement for the amalgamation of Shiva Cement with and into JSW Cement. The proposed merger is intended to create a unified cement platform and generate operational, financial and management synergies.

The consolidation will pool the companies’ financial, managerial, technical, distribution and marketing resources. It will also support backward integration through Shiva Cement’s clinker facility, which is expected to reduce reliance on external procurement and improve supply chain efficiency.

The companies said the transaction would provide greater funding flexibility, reduce financing costs and eliminate inter-company guarantees. It is also expected to simplify the corporate structure by reducing administrative duplication, compliance requirements and consolidation efforts, while aligning the financial statements of both entities.

Under the approved share-exchange ratio, JSW Cement will issue five equity shares with a face value of Rs. 10 each for every 41 equity shares with a face value of Rs. 2 each held in Shiva Cement. The issuance will apply to Shiva Cement shareholders other than JSW Cement and will give the subsidiary’s public shareholders direct ownership in a larger listed company.

The scheme remains subject to approvals from the stock exchanges, the Securities and Exchange Board of India, the National Company Law Tribunal, the Odisha Industrial Infrastructure Development Corporation and other applicable statutory and regulatory authorities. Approval from the companies’ shareholders and creditors may also be required under applicable laws or directions from the tribunal. The transaction is expected to be completed within 12 to 14 months, subject to the timely receipt of these approvals.
