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.

Major cement manufacturers reported a decline in margins for the September quarter, primarily due to lower prices, which led to decreased sales realization.

With the exception of three leading cement producers—UltraTech Cement, Ambuja Cement, and Dalmia Bharat—smaller companies, including Nuvoco Vistas Corp, JK Cement, Birla Corporation, and Heidelberg Cement, experienced a drop in both topline and sales volume during the second quarter of the current fiscal year.

The industry encountered several challenges, including an extended monsoon season, flooding, and a slow recovery in government demand, all contributing to weak overall demand.

Despite these challenges, power, fuel, and other costs largely remained stable across the industry. The all-India average cement price was approximately Rs 348 per 50 kg bag in June 2024, which represented an 11 per cent year-on-year decrease to Rs 330 per bag in September, although it saw a month-on-month increase of 2 per cent.

In the first half of FY25, cement prices declined by 10 per cent year-on-year, settling at Rs 330 per bag. This decline was notable compared to the previous year’s average prices of Rs 365 per bag and Rs 375 per bag in FY23, as reported by Icra.

Leading cement manufacturer UltraTech reported a capacity utilization rate of 68 per cent, with a 3 per cent growth in volume. However, its sales realization for grey cement declined by 8.4 per cent year-on-year and 2.9 per cent quarter-on-quarter during the July-September period.

In response to a query regarding cement prices during the earnings call, UltraTech’s CFO Atul Daga indicated that there had been an improvement in prices from August to September and noted that prices remained steady from September to October. He mentioned that the prices had risen from Rs 347 in August to approximately Rs 354 currently.

Steel companies in India are facing a significant challenge as they contend with an inventory crisis valued at approximately Rs 89,000 crore. This situation has arisen due to a notable increase in steel imports, which has put pressure on domestic producers struggling to maintain sales in a competitive market.

The surge in imports has been fueled by various factors, including fluctuations in global steel prices and increased production capacities in exporting countries. As a result, domestic steel manufacturers have found it difficult to compete, leading to rising stock levels of unsold products. This inventory buildup has forced several companies to reassess their production strategies and pricing models.

The financial impact of this inventory crisis is profound, affecting cash flows and profitability for many steel firms. With domestic demand remaining volatile, the pressure to reduce prices has increased, further complicating the situation for manufacturers who are already grappling with elevated production costs.

Industry experts are urging policymakers to consider measures that can support local steel producers, such as imposing tariffs on imports or enhancing trade regulations. This would help to protect the domestic market and ensure that Indian steel companies can compete more effectively.

As the steel sector navigates these challenges, stakeholders are closely monitoring the situation, hoping for a turnaround that can stabilize the market and restore confidence among investors. The current dynamics emphasize the need for a robust strategy to bolster domestic production and mitigate the risks associated with excessive imports.

JSW Group has signed a Memorandum of Understanding (MoU) with South Korea’s POSCO Group to develop an integrated steel plant in India. This collaboration aims to enhance India’s steel production capacity and contribute to the country’s growing manufacturing sector.

The agreement was formalized during a recent meeting between executives from both companies, highlighting their commitment to sustainable development and technological innovation in the steel industry. The planned facility will incorporate advanced manufacturing processes and adhere to environmentally friendly practices, aligning with global standards for sustainability.

JSW Group, a leader in the Indian steel industry, has expressed confidence that the joint venture with POSCO will bolster its position in the market and accelerate growth. The project is expected to attract significant investments, generating thousands of jobs in the region and contributing to local economies.

As India aims to boost its steel output to meet domestic demand and support infrastructure projects, this partnership signifies a crucial step toward achieving those goals. Both companies are committed to leveraging their expertise to develop a state-of-the-art facility that will produce high-quality steel products while minimizing environmental impact.

This initiative also reflects the increasing collaboration between Indian and international firms to enhance industrial capabilities and foster economic growth. The MoU sets the stage for a promising future in the Indian steel sector, emphasizing innovation and sustainability as key drivers of success.
