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.

A central technical team will visit possible sites identified for the Bhadradri Kothagudem airport in Telangana to assess their suitability for airport development. The team will conduct on-site inspections to evaluate terrain, accessibility and existing infrastructure and will examine factors relevant to safe operations and construction feasibility. The exercise is being carried out in coordination with the state government and local administration to ensure alignment with regional planning objectives.

Members will survey topography, drainage patterns, soil conditions and potential approach paths and will note proximity to habitations and transport corridors. The inspection team will interact with revenue officials, the public works department and representatives of the civil aviation authority to collect technical inputs and records. Satellite imagery and prior site reports will be reviewed alongside ground observations to develop a comprehensive assessment.

Environmental considerations will form a central part of the review, with attention to forest patches, water bodies and biodiversity corridors in and around shortlisted locations. The team will examine regulatory clearances required and will flag areas where detailed environmental impact assessment and mitigation planning are necessary. Land acquisition records and options for minimising displacement will be evaluated in consultation with district authorities.

Findings will be compiled into a technical report for submission to state and central agencies to inform subsequent decision making. The assessment is intended to support careful site selection and to identify infrastructure and connectivity requirements that would need to be addressed during project planning. Stakeholder consultations with local communities and businesses will be part of the follow up process to capture ground level concerns and logistical inputs. The state government will consider the technical report before taking further steps towards detailed design and approvals.

Kirby Building Systems & Structures India has recently broken ground on its fourth manufacturing facility in Manapparai, near Trichy, Tamil Nadu. The plant will be developed across approximately 33.2 acres and have an annual manufacturing capacity of 100,000 metric tonnes, with commercial operations expected to begin by mid-2027.

Once operational, the facility will increase Kirby India’s total annual manufacturing capacity from 300,000 metric tonnes to 400,000 metric tonnes. The expansion is aimed at strengthening the company’s presence in Southern India and enabling faster and more flexible deliveries to customers across key industrial markets.

The new facility will complement Kirby India’s existing manufacturing plants in Hyderabad, Haridwar and Halol, Gujarat. The company said it continues to invest in advanced engineering, automation, digital technologies and manufacturing capabilities to meet growing demand from India’s industrial and infrastructure sectors.

Kirby India has operated in the country for more than 26 years and is supported by over 25 sales offices and more than 150 certified builders. The company has completed more than 45,000 buildings in India, representing a total built-up area of approximately 50 million sq m. The Tamil Nadu expansion also supports Kirby’s broader transition from a PEB manufacturer to an engineering and structural steel solutions provider.

UltraTech Cement Limited, an Aditya Birla Group company, plans to expand its electric vehicle fleet in logistics operations to more than 600 EV trucks by December 2026, strengthening its green transport initiatives.

The company has signed service agreements with leading EV prime mover manufacturers, including Tata Motors, Ashok Leyland, IPLTech, Energy in Motion and Sany, along with their subsidiaries and logistics partners, for deploying electric trucks.

The expanded fleet will transport around five million MT of clinker and other key materials annually across Gujarat, Uttar Pradesh, Madhya Pradesh, Rajasthan, Chhattisgarh, Maharashtra and Odisha. Once operational, the fleet is expected to reduce annual CO₂ emissions by over 1,17,000 tonnes and replace nearly 39 million litres of diesel consumption.

K C Jhanwar, Managing Director, UltraTech Cement Limited, said the company is extending sustainability beyond its manufacturing plants by adopting greener logistics solutions and decarbonising its value chain.

UltraTech has been among the early adopters of sustainable transport in the cement sector, introducing CNG trucks in 2021 and electric trucks in 2024. The company currently operates more than 850 trucks under its green logistics programme, including CNG and electric vehicles.

With a grey cement capacity exceeding 200 MTPA in India, UltraTech is integrating electrification across its logistics network, covering mine-to-plant movement and inter-plant transportation of clinker and other materials.
