Samidha Pathak, Research and Development Manager, Nuvoco Vistas, discusses the future of cement and building materials.

The building materials sector has been a constant arena for innovation, evolving from the ancient use of stone and wood to the contemporary reliance on steel and concrete. Concrete stands out as the most widely utilised man-made material in the present day. Today, concrete remains a cornerstone in construction. The materials have evolved in coming times and will continue to do so with the rapid pace of innovations. As the industry continues to evolve, embracing new materials and techniques is crucial to meeting the demands of the modern world.
With the increasing stride in urbanisation and infrastructural boom, there will be a continued demand for increase in production of building materials. The industry should continue to emerge with new trends to ease the efforts for the end user and maximise productivity. However, it is the need of the hour that these innovations come with reduced carbon footprint and its reliance on virgin natural resources.
Cement sector is already being driven with many initiatives in operations like enhancing kiln and energy efficiencies, firing with alternate fuels to petcoke, utilising alternate raw materials and industrial wastes for clinkerisation, capturing flue gases which all initiatives are not only innovative but also sustainable.

Real time working
In processing and production, real time monitoring has become possible. Carbon Capture Utilisation and Sequestration (CCUS) is an emerging technology to offset the greenhouse gases emission. The ultra high-performance concrete with a composite of cement and fibres is now replacing reinforcement to a considerable extent. Design freedom with specialised concrete mix enabling digitised automated efficient and faster concrete structures is possible today because of 3D printed concrete.
Electricity conservation is possible with piezoelectric concrete, rainwater can now be harvested with previous concrete Smart glasses are able to control the heat and luminosity by changing their stimuli. Like the human body, which is able to self-heal, today concrete is able to heal its own cracks, too. To save water in curing, self-curing concrete is emerging with additives. Nano materials can improve reactivity at a micro level interface.
Construction chemicals are doing wonders in modifying the rheology, grindability, setting, acceleration and workability of cement, concrete, and mortars. The decarbonisation starts with cement, one of the key binders in the building materials and alkali activated binders and geopolymer concrete are eliminating clinker dependency using supplementary cementing materials.
Innovative building materials are reshaping the construction industry, offering novel solutions to longstanding challenges. A key characteristic of these advancements is circularity, emphasising meticulous design for reuse and recycling. This approach aims to significantly diminish waste and resource consumption, marking a pivotal shift toward more sustainable practices in the construction sector. Durability should be another benchmark for innovative materials ensuring that our cities stand the test of time with reduced maintenance. Futuristic innovation should be driven by maintaining resilience and efficiency, sustainable in the long run. Challenges like technical risks, lower acceptability to change, and increased costing can be a few barriers for scaling market acceptability of these innovative materials.
Innovation should become a value system rather than a selling pitch. The resourcefulness of human ingenuity and our innate search for easing jobs will continue to ignite an innovative spark thus overcoming the critical challenges we are facing today.

Cement stocks surged over 5% on Monday, driven by Jefferies’ positive outlook on demand recovery, supported by increased government capital expenditure and favourable price trends.

JK Cement led the rally with a 5.3% jump, while UltraTech Cement rose 3.82%, making it the top performer on the Nifty 50. Dalmia Bharat and Grasim Industries gained over 3% each, with Shree Cement and Ambuja Cement adding 2.77% and 1.32%, respectively.

“Cement stocks have been consolidating without significant upward movement for over a year,” noted Vikas Jain, head of research at Reliance Securities. “The Jefferies report with positive price feedback prompted a revaluation of these stocks today.”

According to Jefferies, cement prices were stable in November, with earlier declines bottoming out. The industry is now targeting price hikes of Rs 10-15 per bag in December.

The brokerage highlighted moderate demand growth in October and November, with recovery expected to strengthen in the fourth quarter, supported by a revival in government infrastructure spending.
Analysts are optimistic about a stronger recovery in the latter half of FY25, driven by anticipated increases in government investments in infrastructure projects.

Steel Ministry Proposes 25% Safeguard Duty on Steel Imports

The duty aims to counter the impact of rising low-cost steel imports.

The Ministry of Steel has proposed a 25% safeguard duty on certain steel imports to address concerns raised by domestic producers. The proposal emerged during a meeting between Union Steel Minister H.D. Kumaraswamy and Commerce and Industry Minister Piyush Goyal in New Delhi, attended by senior officials and executives from leading steel companies like SAIL, Tata Steel, JSW Steel, and AMNS India.

Following the meeting, Goyal highlighted on X the importance of steel and metallurgical coke industries in India’s development, emphasising discussions on boosting production, improving quality, and enhancing global competitiveness. Kumaraswamy echoed the sentiment, pledging collaboration between ministries to create a business-friendly environment for domestic steelmakers.

The safeguard duty proposal aims to counter the impact of rising low-cost steel imports, particularly from free trade agreement (FTA) nations. Steel Secretary Sandeep Poundrik noted that 62% of steel imports currently enter at zero duty under FTAs, with imports rising to 5.51 million tonnes (MT) during April-September 2024-25, compared to 3.66 MT in the same period last year. Imports from China surged significantly, reaching 1.85 MT, up from 1.02 MT a year ago.

Industry experts, including think tank GTRI, have raised concerns about FTAs, highlighting cases where foreign producers partner with Indian firms to re-import steel at concessional rates. GTRI founder Ajay Srivastava also pointed to challenges like port delays and regulatory hurdles, which strain over 10,000 steel user units in India.

The government’s proposal reflects its commitment to supporting the domestic steel industry while addressing trade imbalances and promoting a self-reliant manufacturing sector.

India Imposes Anti-Dumping Duty on Solar Panel Aluminium Frames

Move boosts domestic aluminium industry, curbs low-cost imports

The Indian government has introduced anti-dumping duties on anodized aluminium frames for solar panels and modules imported from China, a move hailed by the Aluminium Association of India (AAI) as a significant step toward fostering a self-reliant aluminium sector.

The duties, effective for five years, aim to counter the influx of low-cost imports that have hindered domestic manufacturing. According to the Ministry of Finance, Chinese dumping has limited India’s ability to develop local production capabilities.

Ahead of Budget 2025, the aluminium industry has urged the government to introduce stronger trade protections. Key demands include raising import duties on primary and downstream aluminium products from 7.5% to 10% and imposing a uniform 7.5% duty on aluminium scrap to curb the influx of low-quality imports.

India’s heavy reliance on aluminium imports, which now account for 54% of the country’s demand, has resulted in an annual foreign exchange outflow of Rupees 562.91 billion. Scrap imports, doubling over the last decade, have surged to 1,825 KT in FY25, primarily sourced from China, the Middle East, the US, and the UK.

The AAI noted that while advanced economies like the US and China impose strict tariffs and restrictions to protect their aluminium industries, India has become the largest importer of aluminium scrap globally. This trend undermines local producers, who are urging robust measures to enhance the domestic aluminium ecosystem.

With India’s aluminium demand projected to reach 10 million tonnes by 2030, industry leaders emphasize the need for stronger policies to support local production and drive investments in capacity expansion. The anti-dumping duties on solar panel components, they say, are a vital first step in building a sustainable and competitive aluminium sector.
