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.

Cement Prices Likely to Rise Rs. 10-15 per Bag from Mid-October

Input costs and steady demand may drive cement price increases

Cement manufacturers in India are likely to raise prices by Rs. 10-15 per bag from mid-October, as they seek to offset persistent increases in power and fuel costs. Emkay Research said its channel checks indicated a high probability of an increase from October 12, supported by the start of the busy construction season and favourable demand-supply conditions.

The sector had implemented similar rate adjustments of Rs. 10-15 per bag during the first quarter, but the increases were insufficient to cover higher operating costs. Prices also softened during July and August because of the monsoon, widening the gap between realisations and input expenses. Delayed plant expansion programmes have pushed clinker utilisation rates towards 79 per cent by FY28, helping to balance market fundamentals.

Emkay Research said steady volume offtake was supporting cement consumption, with non-trade demand driving activity across regional markets. Industry volumes are expected to grow by 7-8 per cent year on year during the first half of FY27, while demand momentum is projected to remain firm over the following 18 months. The outlook includes the busy construction season in the second half of FY27 and infrastructure activity linked to general elections in the first half of calendar year 2029.

The brokerage expects overall cement demand to record a compound annual growth rate of about 7 per cent between FY26 and FY28. However, elevated operating expenses are likely to continue weighing on profitability. Input costs have risen by Rs. 300-400 per t over the past six to seven months, with the full impact expected to become visible in second-quarter earnings and remain persistent through the second half of FY27.

Spot prices for petcoke and imported coal are approximately 20 per cent and 16 per cent above their second-quarter averages, at USD 175 per t and USD 150 per t, respectively. Packing costs have also increased, with polypropylene granule prices rising above Rs. 135 per kg. Emkay Research estimated that second-quarter earnings could decline by Rs. 200-250 per t sequentially because of higher fuel bills and negative operating leverage, and said the sector requires sustained price increases of about Rs. 10 per bag to offset cost inflation.

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.
