What has been the demand growth for slag cement over the last two-three years, and how it is expected to pan out in the next three years?
The awareness about the superiority of slag cement in performance over other types of cements, especially in aggressive environments like coastal areas, marine works, effluent treatment plants, foundation works, and other similar structures is increasing amongst the engineers and the consultants.

The availability of slag cement in India is in to geographical areas, which are closer to integrated steel plants where granulated blast furnace is available as by-product. The production of slag cement is also dependent upon the availability of blast furnace slag, which in turn depends upon the production capacity of steel in India.

At present, the share of slag cement ranges between 8 to 10 per cent of the total cement consumption in India. It is expected to increase due to increase in acceptance of slag cement and also by the government approvals and specifications like Engineer’s India Ltd, etc. during the next three years.

What is the demand-supply scenario of slag cement and what are the factors that will boost its demand?
At present, the slag cement, which is produced in India, is consumed without any difficulty. The share of slag cement can be increased provided adequate quantity of blast furnace slag is available for production of slag cement. It may be interesting to note that during the production of PPC cement only 25 per cent of the total production of fly ash is consumed by the cement industry in India, while 100 per cent slag from steel plants is utilised by the industry to produce slag cement.

There is distinct preference for slag cement amongst engineers, consultants and consumers for PSC over PPC.

The following factors are likely to boost the demand of slag cement:
a)Aggressive conditions, i.e., sulphate, chloride attack from soil and polluted water and alkalis coming from aggregates in many part of the country. Best example is new green field project of petroleum refinery by HPCL coming up at Barmer-Rajasthan where slag cement is specified.
b)Easy availability in all geographical areas in the country.
c)Awareness about the advantages of slag cement over other types of cement especially in aggressive environmental conditions.
d)Consideration of long term strength and durability of structures over the initial strength alone.
e)Increased production of steel in the country and availability of blast furnace slag.

Please enumerate technical and environmental advantages of slag cement and areas of its utility?
Slag cement has distinct advantages over other types of cement in the following quality parameters:
a)To make concrete more impermeable to ingress of the harmful liquids and solids.
b)To enhance the durability of concrete by rendering its micro structure denser and cohesive.
c)To develop stronger bond with steel over the period and to resist cracking in concrete.
d)To develop higher long term compressive and tensile strength in concrete.
e)The cohesiveness of concrete mix using slag makes it easy to pump, place, compact and finish as compared to concretes using other types of cement.
f)The concrete using slag cement are lighter in colour and reflect more light and avoids rise in temperature especially in urban areas.
g)Concrete with slag cement is aesthetically more pleasing.
h)Slag cement can utilise blast furnace slag up to 70 per cent while PPC can use fly ash only up to 35 per cent as per the Indian Standards. Thus, slag cement is more environmental friendly than PPC and other types of cement.
Areas of application:
a)Slag cement can be used for all types of civil engineering works as per the IS – 455 of 2015 standards.
b)Slag cement is very beneficial in coastal and marine environments.
c)Advantages in construction of effluent treatment plants, water and sewage disposal works.
d)All foundation works, basement and underground structures.
e)Irrigation works, dams, canal lining and river training works.
f)Bridges, metro rails, highways, ports and other infrastructure works.

What is the supply situation of raw materials for slag cement, particularly availability of slag?
The availability of slag is limited in India as the slag produced by the integrated steel plants through blast furnace route is only utilised for production of slag cement. It is estimated that nearly 15 to 18 million tonnes of slag is produced per annum by steel plants in India.

The entire quantity of blast furnace plant is utilised by the cement industry in production of slag cement. The same situation is likely to continue as the growth of cement industry is more than the growth of steel industry.

What are the cost and price trends of slag cement when compared to OPC?
The cost of slag cement ideally should be more than OPC due to its numerous advantages. In most of the Eastern markets, the slag cement is sold at premium. PPC pricing is generally lower by a few rupees a bag as compared to OPC. The advantages of slag cement over PPC are now recognised, and in most of the markets, slag cement commands a better price than PPC.

Do you have expansion plans on the anvil and what is the usual gestation for setting up a slag cement plant?
We do have the plan for expansion to produce more quantity of slag cement. However, as mentioned earlier, it depends upon the availability of blast furnace slag. In a way, it is related to the expansion of the source of blast furnace slag. The gestation period in setting up a new cement unit is about two years.

World Environment Day spotlight on innovation and circularity

On World Environment Day, the Indian cement industry reiterated its commitment to supporting India’s climate ambitions through sustainable manufacturing, resource efficiency and the adoption of cleaner technologies.

The Cement Manufacturers’ Association (CMA) said the sector remains aligned with the Government of India’s Net Zero commitments and is accelerating efforts to reduce its environmental footprint while supporting the country’s infrastructure and development agenda.

Parth Jindal, President, CMA and Managing Director, JSW Cement, said the industry is increasingly adopting cleaner technologies, improving energy efficiency and expanding the use of alternative fuels and raw materials. He also highlighted the growing importance of circular economy practices, where industrial by-products and waste streams from one sector are utilised as resources in another.

“The Indian Cement Industry is aligned to the Government’s commitments on carbon mitigation and is accelerating the adoption of cleaner technologies, resource efficiency and circular economy practices while actively exploring the potential of Carbon Capture, Utilisation and Storage (CCUS) as a critical pathway for deep decarbonisation,” said Jindal.

He added that coprocessing industrial waste and by-products helps conserve natural resources, reduce disposal requirements and lower the environmental footprint across multiple sectors.

According to Jindal, sustainability is no longer limited to manufacturing processes but is increasingly influencing investment decisions, innovation strategies and long-term growth plans within the industry.

Echoing similar views, Dr Raghavpat Singhania, Vice President, CMA and Managing Director, JK Cement, said sustainable development extends beyond emissions reduction and must also focus on responsible resource utilisation and waste minimisation.

“Sustainability in the built environment cannot be measured by emissions alone. It is equally about how efficiently we use resources, how effectively we minimise waste and how responsibly we create the infrastructure that will serve future generations,” said Singhania.

He noted that the cement industry is advancing its sustainability agenda through greater resource efficiency, increased circularity, technological innovation and continuous improvements in manufacturing practices. As a key contributor to India’s infrastructure development, the sector has a critical role to play in balancing economic growth with environmental responsibility.

On the occasion of World Environment Day, industry leaders reaffirmed their commitment to supporting India’s climate goals while delivering the materials required for resilient, durable and sustainable infrastructure.

Environmental sustainability requires immediate action, not just long-term commitments and discussions. Recycling, circular economy practices, and technology-driven waste management can help industries reduce environmental impact while supporting sustainable growth.

Author: Jignesh Kundaria, Director and CEO, Fornnax Technology

World Environment Day serves as an important reminder that environmental sustainability can no longer remain confined to discussions, reports, or long-term commitments. The environmental challenges facing the world today demand immediate, measurable, and collective action. Across industries and communities, waste generation continues to outpace our ability to process it responsibly, placing increasing pressure on ecosystems, natural resources, public health, and the well-being of future generations.

One of the most significant shifts required today is a change in how society perceives waste. Rather than being viewed as a material to be discarded, waste must be recognised as a valuable resource that can contribute to both economic growth and environmental protection when managed through the right technologies and systems. This mindset forms the foundation of the circular economy model that countries across the world are increasingly adopting to reduce landfill dependence, recover valuable materials, and create more sustainable industrial ecosystems.

India has made meaningful progress in strengthening awareness around sustainability, recycling, and environmental responsibility over the past decade. Significant efforts are being made to formalise the recycling sector through improved infrastructure, technology adoption, policy implementation, and broader stakeholder participation. These developments are creating a stronger foundation for responsible waste management and resource recovery across the country.

However, achieving long-term environmental impact requires collaboration from all stakeholders. Industries, policymakers, technology providers, and communities must work together with greater accountability to strengthen recycling ecosystems, encourage responsible waste management practices, and create sustainable outcomes through consistent execution rather than temporary interventions.

As someone closely associated with the recycling industry, I firmly believe that technology will play a decisive role in addressing future environmental challenges. Advanced recycling systems have the potential to recover valuable resources, reduce pollution, minimise landfill burdens, and conserve energy, creating a more sustainable future for generations to come. This belief is deeply reflected in Fornnax’s motto, “Committed to Create a Green Future,” which embodies our commitment to building long-term environmental value through innovation and responsible action.

At the same time, technology alone cannot deliver meaningful change. Real progress requires intent, awareness, participation, and a shared sense of responsibility. Sustainable development can only be achieved when innovation is supported by collective action and a genuine commitment to environmental stewardship.

On this World Environment Day, let us move beyond conversations and take meaningful steps towards creating a cleaner, greener, and more sustainable planet. By embracing innovation, strengthening recycling ecosystems, and acting responsibly today, we can create lasting environmental impact and secure a better future for generations to come.

Dalmia Cement executed a Business Transfer Agreement with Jaiprakash Associates and Adani Infra, to acquire 5.2 MnTPA of cement capacity across Madhya Pradesh and Uttar Pradesh.

Dalmia Cement (Bharat) announced on May 22, 2026 that it had signed a Business Transfer Agreement with Jaiprakash Associates Limited and Adani Infra (India) Limited for the acquisition of cement plants located at Rewa in Madhya Pradesh and Churk, Chunar and Sadwa in Uttar Pradesh. The deal was struck at an enterprise value of ₹2,850 crore and is expected to close within two weeks of execution.

The acquired assets from Jaiprakash Associates include 5.2 MnTPA of cement capacity and 3.3 MnTPA of clinker capacity. The package also covers 99 MW of thermal power capacity and railway sidings at Rewa, Chunar, and a common siding at Churk. This infrastructure gives the acquisition immediate operational utility beyond just production tonnage.

The transaction has a long backstory. Dalmia Cement had originally entered into a framework agreement with Jaiprakash Associates in December 2022, covering the sale of these business assets along with a long-term clinker supply arrangement. However, before the deal could be completed, Jaiprakash Associates was admitted to insolvency proceedings under the Insolvency and Bankruptcy Code. The earlier agreements could not be consummated as a result.

In an official statement, Puneet Dalmia, Managing Director & CEO, Dalmia Bharat, said, “I am very excited about addition of these assets in our portfolio. This serves as a great strategic fit for Dalmia. It helps us move forward in our journey to be a pan India player and provide a strong head start to serve the high potential markets in Central region. I am optimistic that the expansion potential of these assets along with close proximity with Dalmia’s captive mines will help us create a capacity hub for the future”.

Following the approval of Adani Group’s resolution plan for Jaiprakash Associates under the IBC framework, Dalmia approached the new management to revive discussions. The fresh Business Transfer Agreement was executed to settle all pending disputes, legal proceedings, and arbitration matters arising from the original framework agreement with Jaiprakash Associates.

Expanding market reach

Dalmia added, “Our familiarity with these assets under the earlier tolling arrangement gives us a deep understanding of the facilities and helps us establish strong connect with channel partners and vendors. We believe that this will help us in faster ramp up of capacities and quicker inroads into the market. As we look forward, I am very confident that we will be able to leverage the strengths of Dalmia to operate these assets in a manner where we can maximise value creation for all our stakeholders.”

With the addition of these plants, Dalmia Bharat’s total installed cement capacity will rise to 54.7 MnTPA upon consummation. The company has further expansion projects underway at Belgaum, Pune, and Kadapa, which are expected to take overall capacity to 66.7 MnTPA by Q2 to Q3 FY28.

The Central India location of the Jaiprakash Associates plants gives Dalmia Bharat faster access to markets in Madhya Pradesh and Uttar Pradesh than a greenfield build would have allowed. The company also cited debottlenecking and brownfield expansion as near-term opportunities at the acquired sites. Dalmia Bharat said the assets were expected to contribute positively to EBITDA and overall returns, given the pricing environment in the region and the company’s cost structure.
