Blending Green and Grit

Blended cements are slowly but steadily increasing their presence felt in the market. With the introduction of composite cement, the industry’s green commitment is getting reinforced further.

Blended cements – Portland Slag Cement (PSC) and Portland Pozzolana Cement (PPC) – are making headway by cornering a major share of the cement market, nudging the Ordinary Portland Cement (OPC) which was the market leader at one time, into the corner, in the recent years. The exciting journey of blended cements has seen them taking an equal share of 50:50 in the late 1970s even before introduction of fly ash-based blended cement, only to lose share to OPC which touched 76 per cent by 1983, and to totter at about 30 per cent by the end of the twentieth century, it has now scaled the peak market share of three-fourths.

"Ever since government allowed blending of cement with OPC, there has been continuous growth in the sales of PSC/ PPC cement. There has been a very good penetration of blended cements in the market. Earlier OPC used to be the market leader in India. However, today, it represents only about 20-25 per cent of the market share. In this context, it is encouraging to note that nearly 75 per cent of cement production in India at present is in the form of blended cement of various types," says Raakesh Jain, Chief Sales Officer, Nuvoco Vistas Corp.

Blended cements have been gaining almost over the last couple of decades, particularly since introduction of fly ash-based cement, which combines the advantages of OPC on cost front, and strength and durability of slag cement, its blended peer. "This has been possible through education of customers on the merits of blended cement, which has led to higher awareness and increased usage," says Ujjwal Batria, Chief Operating Officer, Dalmia Cement (Bharat) Limited.

With the introduction of composite cements, the market is expected to become even more exciting in the years to come.

Institutions still prefer OPC
Still, OPC is preferred in certain geographies and particularly by several institutional users, for various reasons. "While there is an improvement in the acceptance of blended cements, there are certain segments like RMCs, select infrastructure projects, where the preference continues to be for OPC due to the cost economics and flexibility available to the contractor," says Nilesh Narwekar, CEO, JSW Cement.

OPC grades 43 & 53 are more preferred in major infrastructure projects such as national highways, bridges, transmission lines, power plants, industrial and residential structures. "Also in major infrastructure projects, OPC Grade 43/ 53 is approved through the Central/ state government/ local governing bodies/ institutions over PPC/ PSC, making OPC a preferred product in institutional segment," says Jain.

Institutional customers have their own batching plants in most cases and prefer to do blending at their end. However, efforts of the blended cement manufacturers over the last few years in educating their customers on environmental benefits and durability they offer have resulted in their increased use.

Applications
Both PPC and PSC are environment-friendly cements as they use industrial by-products as an input. PPC classically uses fly ash, while PSC uses slag generated in the blast furnace of steel plants.

Blended cements are suitable for high rainfall areas and coastal areas as these offer higher longevity of structures, offering the highest resistance against sulphate and chloride attacks and environmental pollutants. PSC’s chemical composition gives it high compressive strength and offers excellent resistance to chloride and sulphate attacks. It boasts a superior finish and minimise shrinkage and cracks. For this reason, it is mostly used for marine constructions.

PPC’s hydration process is slower than PSC cement, therefore, making it suitable for mass concreting. It shows greater resistance to aggressive weather and is cheaper than PSC. PPC has an amazing pore refinement leading to an improved density of concrete, says Batria.

New kid on the block
Taking cue from the Bureau of Indian Standards’ (BIS) decision to permit manufacturing and selling of composite cement in India a couple of years ago, several cement manufacturers have already introduced composite cement. Composite cement is a blend of fly ash and slag based cement, offering the best of both worlds.

Composite Cement is being typically manufactured by companies where both these commodities are readily available. Eastern region is where most of the players have introduced composite cement by now. JSW has introduced it in Karnataka and in the east, while Dalmia Cement has introduced it in the eastern region, and Nuvoco already has a thrust towards blended cements.

"We have already introduced composite cement to our customers in Karnataka and more recently in Salboni. We also plan to make it the core product from Jhajpur, our upcoming plant in Odisha," Narwekar says.

Being a new product in the market, the manufacturers are already undertaking awareness programmes for their customers and influencers like engineers and architects. Composite cement is still not accepted in RCC (Reinforced Cement Concrete) by BIS posing a challenge in selling it as an all-purpose cement, besides getting government approvals for composite products.

Looking ahead
If one has to go by what the experts have to say, bended cements are going to be the future of cement industry, being greener and offering several advantages. Perhaps in the process of vouching for its future of cement in blended ones, JSW Cement, being largest manufacturer of PSC, is planning to take a plunge into blended cements headlong.

"We are planning to double our cement production capacity in the next few years to meet the growing demand for "Green" cement in the eastern region by a combination of brownfield expansions at our new facility at Salboni, West Bengal and Shiva Cement, Odisha. These projects are expected to be commissioned in various phases until 2023. We are also debottlenecking our plants in South and evaluating opportunities for a grinding unit GU in TN," Narwekar says. JSW is in the process of commissioning a new greenfield 1.2 million tonnes per annum plant in Jajpur, Odisha, which is expected to be optimizes by December 2019.

In order to promote sustainable alternatives in every area in line with India’s commitment at the Paris Summit, blended cements, which use factory waste and other by-products, should be encouraged through use in government projects. Thus, cement manufacturers, who are planning to increase their use of alternative fuels and raw materials (AFR), will be contributing immensely to sustainable manufacturing and sustainable products in future.

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.
