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.

Aditya Birla Group has entered the wires and cables market through Ultravolt, extending UltraTech’s move from building materials into building solutions. The shift builds on UltraTech Building Solutions, a multi-category platform that already addresses customers across different stages of construction and extends beyond cement into ready-mix concrete, waterproofing, tile-fixing solutions and mortars.

The company intends to enter with scale, seeking presence across 100,000 retailers in more than 500 districts and availability through 5,000 plus UltraTech Building Solutions (UBS) outlets. The portfolio spans house wires, light-duty cables, communication cables, solar cables and low-tension and industrial cables to meet changing electrical requirements driven by solar installations, communications infrastructure and industrial automation.

An upstream advantage begins in the Group’s metals ecosystem, with conductor quality central to product performance. Ultravolt wires will use TruePure Copper, defined as 99.97 per cent pure electrolytic-grade annealed copper sourced from Hindalco, providing greater control over raw material quality and provenance and supporting electrical performance, safety and durability.

The business also targets the electrician community as a decisive influence on product choice and installation quality. The Wires and Cables Business has launched a Skill India Electrician Training Programme in partnership with the Electronics Sector Skills Council of India that aims to train and certify more than 40,000 electricians across India over the next year, focusing on safe wiring practices, correct installation and advanced wire technologies and offering Skill India-aligned certification and identification credentials.

The move combines market opportunity, UltraTech’s construction ecosystem, manufacturing capability and Group-level resources. A large Gujarat facility, advanced machinery and in-house testing and research and development underpin the product strategy, which is designed for both traditional and emerging applications. The ambition is to build a scaled national brand and become one of the top two players within five years, making the Group an integral participant in modern building infrastructure.

The ecological restoration of Ramco Cements’ limestone mine at Pandalgudi in Virudhunagar district, Tamil Nadu, has received international recognition with the site being awarded Advanced Certification by The Global Biodiversity Standard (TGBS). The recognition makes Pandalgudi the first site in Peninsular India to receive the certification and places it among globally recognised biodiversity restoration projects.

TGBS, recognised by the International Union for Conservation of Nature (IUCN) and the Convention on Biological Diversity (CBD), assesses biodiversity restoration projects based on scientific evaluation and their contribution to ecosystem recovery and local communities. The certification is supported by more than 250 scientists and academics worldwide.

Spread across over 500 acres of worked-out mine areas, the restoration project includes a certified 234-acre site. Initiated in 2018 with technical support from Auroville Botanical Gardens, the project began plantation activities in 2019 and is expected to be completed by 2027. More than 430,000 native trees and shrubs belonging to 150 ecologically significant species have been planted at the site.

The restored mine, which was once a barren landscape with limited biodiversity, has recorded over 72 bird species and 53 butterfly species. The project has also captured an estimated 10,000 tonnes of carbon dioxide over the past seven years, supporting broader sustainability and carbon reduction goals.

Opened officially in 2022, the site has attracted more than 13,000 visitors through educational programmes for schools, colleges and training institutions. The restoration initiative has also contributed to the development of the Rajapalayam Masterplan and supported Tamil Nadu’s carbon neutrality ambitions.

Commenting on the achievement, Mr P. R. Venketrama Raja, Chairman, Ramco Group, said the company aims for the Pandalgudi restoration project to serve as an inspiration and blueprint for the mining industry in India. Dr David Bartholomew, CEO, The Global Biodiversity Standard, highlighted the project’s long-term commitment to biodiversity recovery and independent assessment of ecological outcomes.

The certification reinforces Ramco Cements’ focus on sustainable mining practices and ecological restoration as part of its commitment towards a carbon-neutral future.

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.
