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.

Nuvoco Vistas Corporation Limited is celebrating a decade of operations under the theme ‘Dus Saal Bemisaal’, highlighting its expansion in India’s building materials sector. The company has grown from a single cement manufacturing facility into a diversified organisation operating across cement, ready-mix concrete (RMC) and modern building materials.

The company’s journey began in 2014 when its parent, Nirma Group, commissioned a 2 million metric tonnes per annum (MMTPA) greenfield cement plant at Nimbol, Rajasthan. A major milestone followed in October 2016 with the acquisition of Lafarge India, significantly expanding its manufacturing footprint.

Nuvoco strengthened its market presence through the acquisition of Emami Cement, now NU Vista Limited, in 2020, followed by its public listing in 2021. In April 2025, the company added Vadraj Cement to its portfolio, strengthening its presence in western India.

Nuvoco has an operating cement capacity of 27 MMTPA and 14 manufacturing units, including the Kutch and Sachana facilities in Gujarat, which are in advanced stages of completion. It also operates 58 ready-mix concrete plants across India and offers a range of modern building materials.

The company aims to increase its cement capacity to 35 MMTPA by FY2027-28, representing approximately 15-fold growth over the decade.

Reflecting on the milestone, Hiren Patel, Chairman, Nuvoco Vistas Corporation Limited, said, “From our beginnings at Nimbol to the organisation we are today, every milestone has added a new chapter to Nuvoco’s journey and strengthened our belief in building for the long term.”

The company continues to focus on capacity expansion, operational efficiency, innovation and sustainability while strengthening its position in India’s construction materials market.

Jammu and Kashmir government has notified the City Gas Distribution (CGD) Policy, 2026, following its approval by the Council of Ministers headed by Chief Minister Omar Abdullah. The policy sets out a phased framework for expanding Piped Natural Gas (PNG) and Compressed Natural Gas (CNG) access for households, businesses, industries and the transport sector across the Union Territory.

CGD networks will be expanded in phases across all 20 districts, with the aim of bringing reliable natural gas closer to consumers and supporting a gradual shift from conventional fuels. The government said the policy is designed to improve energy access while creating an investor-friendly and time-bound environment for gas distribution projects.

The policy provides for single-window and time-bound clearances, streamlined procedures for setting up CNG stations and standardised norms for the Right of Way. These measures are intended to reduce procedural delays, simplify project implementation and facilitate investment in natural gas infrastructure.

It also prioritises gas connectivity for major industrial estates, including those in Kathua, Samba and Pulwama. Improved access to natural gas is expected to support industrial activity, enhance energy efficiency and help businesses manage fuel costs, while strengthening their competitiveness and encouraging investment in the clean-energy sector.

The policy is also expected to create opportunities for local employment, apprenticeships and skill development in the construction, operation and maintenance of gas distribution networks and related services. Abdullah described the measure as an important step towards cleaner growth, sustainable development and a modern energy ecosystem in Jammu and Kashmir, saying it would expand reliable energy access and support industry and investment.

JSW Cement has commissioned an additional 1 MTPA grinding unit at Nagaur in Rajasthan. MTPA refers to million tonnes per annum. The commissioning has increased the company’s total cement grinding capacity to 25.10 MTPA, while its total clinker manufacturing capacity, including capacity at its joint venture JSW Cement FZC, stands at 9.74 MTPA.

The company began operations in North India in March 2026 with the Nagaur Integrated Plant, which comprised a 3.30 MTPA clinkerisation unit and a 2.50 MTPA cement grinding unit. Following the latest commissioning, the plant’s total cement grinding capacity has risen to 3.50 MTPA.

The expanded facility is expected to strengthen JSW Cement’s ability to serve cement demand across Rajasthan, Haryana, Punjab and the National Capital Region. The project has been funded through a combination of equity and long-term debt, according to the company.

During the quarter ended 30 September 2026, JSW Cement also commissioned an Alternate Fuel Handling System and a Waste Heat Recovery System (WHRS) at the Nagaur Integrated Plant. The company said the additions formed part of its broader effort to improve operational efficiency at the facility.

Nilesh Narwekar, chief executive officer of JSW Cement, said the additional grinding capacity was a strategic priority that would support the company’s expansion in North India. He added that the unit had been commissioned within the expected timeline, reflecting the company’s project execution capabilities, and that the alternate fuel and waste heat recovery systems were expected to substantially reduce production costs going forward.
