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.

India’s output across eight core industries grew 4.8 per cent year-on-year in August 2026, easing from the revised 5.0 per cent growth recorded in July, according to provisional data released by the Ministry of Commerce and Industry. The Index of Core Industries (ICI), which tracks eight key infrastructure sectors, accounts for a significant share of the Index of Industrial Production.

Cement production led the expansion with growth of 12.5 per cent, followed by electricity at 11.6 per cent and iron ore at 5.5 per cent. Steel output increased 3.4 per cent, while refinery products rose 2.6 per cent during the month. The ministry identified cement, electricity and iron ore as the main contributors to overall core sector growth in recent months.

The gains were partly offset by contractions in several sectors. Coal output declined 3.8 per cent year-on-year, while natural gas and crude oil production fell 4.9 per cent and 3.6 per cent, respectively. Fertiliser production recorded the sharpest decline, falling 12.4 per cent in August.

Cumulative growth in the ICI during April-August 2026 stood at 4.3 per cent, compared with 2.4 per cent in the corresponding period a year earlier. Steel output increased 4.1 per cent during the period, while cement and electricity production grew 10.3 per cent and 9.6 per cent, respectively.

Coal, natural gas, crude oil, refinery products and fertilisers recorded negative cumulative growth during April-August. Their contractions stood at 3.2 per cent, 4.4 per cent, 4.1 per cent, 1.4 per cent and 6.7 per cent, respectively. The ministry also revised the final ICI for July to 120.8 from the earlier provisional estimate of 121.2, resulting in a downward revision in the month’s growth rate to 5.0 per cent from 5.4 per cent.

Hard Worker Wins Three Honours at Kyoorius Design Awards

The Ramco Cements Limited’s construction chemicals brand, Hard Worker, has won three honours at the Kyoorius Design Awards 2026, including the Grand Prix – Grey Elephant in the Design in Action category.

The brand also secured two Blue Elephant honours, one for Design in Action and another for Packaging, recognising the design approach behind its brand identity and packaging.

Launched in 2025, Hard Worker entered the construction chemicals segment with the brand promise, “Hard-working products for hardworking people.” Its visual identity uses animals and birds to represent product benefits. The camel represents the water-retention capability of Hard Worker Eco Plaster, while the cheetah represents the speed and performance of Hard Worker Block Fix.

The visual language has been extended across packaging, retail, communication, literature, digital platforms and other brand touchpoints. Hard Worker uses bold colours, distinctive animal illustrations and simple visual storytelling to communicate product benefits across markets and audiences, including construction workers and applicators.

“For Hard Worker, design was never an afterthought. It was fundamental to how we wanted to build the brand. In a category that is largely functional, we wanted to create a brand that people could recognise, understand and remember instantly. The Kyoorius recognition is a wonderful validation of this design-led approach,” said Mr. AV Dharmakrishnan, CEO, The Ramco Cements Limited.

Mr. Balaji K. Moorthy, Executive Director – Marketing, Ramco Cements said “In a category where communication has traditionally been product-led and functional, we wanted Hard Worker to stand apart by making design an integral part of the brand experience. From the distinctive animal-led packaging to our communication across consumer and trade touchpoints, every element was designed to make the brand more memorable and the product benefits easier to understand.”

Within its first 12 months, Hard Worker crossed Rs 3.5 bn in sales. The latest recognition follows six honours secured by the brand’s campaign at the Kyoorius Creative Awards earlier in 2026, including the Grey Elephant Grand Prix for its Eco Plaster film.

The Kyoorius Design Awards recognise outstanding design work in India’s visual communications sector across multiple categories and platforms. The 2026 awards were announced on 12 September in Goa.

The Ramco Cements Limited is part of the Ramco Group and operates across cement and allied building-material solutions. Hard Worker is its construction chemicals brand, offering solutions across key construction applications.
