Concrete: A Highly Sustainable Building Material

Concrete as a material can be viewed in different ways. Here a builder and developer explains how versitle the material is and its superiority.

With the term ?concrete jungle? having become to popular and widely used, it is easy to overlook that this building material has been around for so long for very good reasons. Also, that it has some excellent attributes which make it very important in today?s context.

Yes, it is easy to produce and use, but the fact is that concrete is an eminently environmentally friendly building material during the entire span of its life cycle, beginning from its production as a raw material right until it is demolished. This renders it the perfect and obvious building option for the construction of sustainable homes.

The cement utilized in concrete is sourced from limestone, which is an abundantly available mineral that will literally never deplete. However, one can also manufacture concrete from materials such as slag cement and fly ash, both of which are generated by industries like steel mills and power plants as waste byproducts. From the point of recycling of existing resources, concrete is therefore a real boon to the planet.

Concrete is also highly durable, and is used in erecting buildings which are not subject to rust, do not burn or otherwise degrade. In fact, buildings built with concrete have twice or even thrice the life- span of buildings erected with many other construction material. The life-spans for concrete building products can be double or triple those of other common building materials.

What is equally important from a sustainability perspective is that the use of concrete in forming the foundation, floors and walls of a building renders it extremely energy-efficient. One of the benefits of this building material is its ability to absorb and retain heat. In other words, people who live in homes built of concrete save significantly on both cooling and heating bills. In a concrete building, one can install air conditioners of lower capacity, resulting in significant electricity savings.

Also, concrete reduces the incidence of processes that result in urban heat islands. When concrete, which is inherently light in colour, is used to build pavements and roofs, the end result is that less heat is absorbed and more incoming solar radiation is deflected. Finally, concrete as a building material results in the least waste of raw building materials, as it can be manufactured and used in the actual quantities required to build a building or other project. Once a building or structure built of concrete has completed its life-cycle or fulfilled the purpose for which it was erected, the concrete can be recycled into aggregate which can then be used to lay concrete pavements or provide an underlying base for roads.

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.

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.
