Is there a Real Need for Alternate Cements – A Review

The possibility of alternative cements reducing carbon emission
Most economic growth in this century is projected to be in developing countries and statistics already show that these are the same places that are now consuming 93% of the cement produced globally. Consequently, global demand for cement is presently growing at a rate of about 4 % per annum. It is in these places of high growth and need for new infrastructure where aggressive changes in construction practices may also initiate fundamental change in the chemistry of infrastructure cement.
While the composition of OPC has remained largely the same since last century, and the mechanisms of OPC hydration and structure of C-S-H remain difficult to interpret. However, major advances in the use and performance of cement have come from three fundamental areas: (1) construction technology; (2) the science and engineering of composite materials; and (3) admixture chemistry, both organic and inorganic.
Alternative cements could be defined as inorganic cementitious materials that can be used for construction, but whose properties and composition are not yet specified by existing standards, codal practices and regulations.
The evolution of new cement types will need to overcome both technical and non-technical barriers. Requirements for mechanical performance and long-term durability are critical, but standards and specifications, whether prescriptive or performance-based, will also require robust evolution. In addition, confidence in new materials must be acquired by the end user (e.g., contractors) in the field-based application of new cements. In each case, some application flexibility will be needed, because new cements may need to be processed and placed in a manner somewhat different from OPC-based concrete.
Substantial progress should be made scientifically, before these cements can be manufactured at industrial scales. On the other hand, Calcium Sulpho Aluminate cements (CSA) appear to be emerging as a leading alternative cement over the next decade. Indeed, in near future commercial production of CSA cements appears to be implemented in the Western world.
In broader terms, the stimulus and time scale to innovation and evolution of alternative cements depends on public policy. Scientific developments and technology can inform debates, but if the cement industry is to remain competitive in the face of possible policy-driven mandates, it needs to present realistic, viable and impactful alternatives to traditional OPC.
A shift away from OPC will tend to compromise the calcium buffer, and hence the extent of passivity afforded, but simultaneous changes in reinforcing materials away from ferrous metals (e.g. fiber-reinforced polymers) may reduce the need for corrosion resistance. Nevertheless, because of the driving force to reduce CO2 emissions, some alternative cements that may emerge in the next 100 years appear promising.

The 15th Cement Expo 2025 will spotlight India’s cement industry’s growth, innovation, and sustainability, showcasing cutting-edge solutions for a greener future.

- Rustic Texture: Mimicking natural stone or aged plaster for an earthy, vintage feel.
- Wave Patterns: Adding a sense of movement and fluidity to walls, perfect for living rooms and entryways.
- Sand Finish: A subtle grainy effect that provides a sophisticated touch.
- Monochrome interiors where walls serve as a sleek backdrop.
- High-gloss or matte-painted walls that need a seamless base.
- Spaces with minimal décor where the walls themselves make a statement.
- Chevron or Herringbone: A dynamic, sophisticated look that pairs well with both modern and mid-century décor.
- 3D Raised Panels: Using putty to craft subtle raised patterns, adding a sculptural effect to the wall.
- Asymmetrical Shapes: For a bold and avant-garde touch.
- These patterns work best in bedrooms, study areas, or accent walls in open spaces.
- Statement walls in living rooms and foyers.
- Elegant dining areas where a touch of opulence is desired.
- Boutique-style bedrooms with a rich, textured finish.
- Children’s rooms or play areas, creating a fun and dynamic atmosphere.
- Bedrooms with a soothing pastel gradient for a calming effect.
- Dining spaces where a bold color fade adds character.
- Luxurious master bedrooms and dressing areas.
- Accent walls in dining rooms or home bars.
- Commercial spaces like boutiques and salons.
- Choose the Right Putty: Opt for a premium wall putty like Birla White WallCare Putty to ensure durability, a smooth finish, and long-lasting appeal.
- Prepare the Surface: Ensure the walls are clean, dry, and free from loose particles before application.
- Apply in Layers: Depending on the design, putty can be applied in single or multiple layers for the desired effect.
- Use the Right Tools: Trowels, spatulas, sponges, or patterned rollers help create specific textures and patterns.
- Seal with Paint or Polish: Once the putty is dry, finishing it with paint, polish, or protective coatings enhances its aesthetic and durability.

- Investment in alignment with the strategic goal of becoming a PAN India company and achieving 75 MnT capacity by FY28
- Increases capacity primarily to meet growing demand in Western India along with existing regions
Dalmia Bharat Limited, one of India’s leading cement companies, through its subsidiaries, has announced a strategic investment of approximately Rs 3,520 Crore in the states of Maharashtra and Karnataka. As part of this initiative, the company will establish a 3.6 MnTPA clinker unit and a 3 MnTPA grinding unit at its existing Belgaum plant, Karnataka coupled with a new greenfield split grinding unit with a capacity of 3 MnTPA in Pune, Maharashtra. The capex will be funded through a combination of debt and internal accruals. With this expansion, Dalmia Bharat’s total installed cement capacity will increase to 55.5 MnTPA, after considering the ongoing expansion of 2.9 MnT at Assam and Bihar. These new units are expected to be commissioned by Q4 FY27.
The Belgaum Grinding Unit will cater to the underserved Southern Maharashtra markets while enhancing share in the existing region by improving penetration. On the other hand, Pune Grinding Unit will entirely cater to the untapped Western Maharashtra markets. The initiative is a part of the company’s vision to be a PAN India player and achieve 75 MnTPA capacity by FY28 and 110-130 MnT by 2031.
Speaking on the development, Mr. Puneet Dalmia, Managing Director & CEO, Dalmia Bharat Limited, said, “This investment is a significant step in our Phase II expansion strategy, bringing us closer to strengthen our position as a pan-India player and to reach intermittent goal of 75 MnT capacity by FY28. The increase in our production capacity is primarily to meet the growing infrastructure demand in Western India.” He further added, “We remain committed in realising our goals of capacity expansion, while staying focused on operational excellence and creating long-term value for our stakeholders. The capacity additions will also continue to be in line with Dalmia Bharat’s sustainability-driven approach and its commitment to supporting India’s infrastructure and development goals.”
About Dalmia Bharat: Founded in 1939, Dalmia Bharat Limited (DBL) (BSE/NSE Symbol: DALBHARAT) is one of India’s pioneering cement companies headquartered in New Delhi. With a growing capacity, currently pegged at 46.6 MnT, Dalmia Bharat Limited (including its subsidiaries) is the fourth-largest cement manufacturing company in India by installed capacity. Spread across 10 states and 15 manufacturing units. Dalmia Cement (Bharat) Limited, a subsidiary of Dalmia Bharat Limited, prides itself at having one of the lowest carbon footprint in the cement world globally. It is the first cement company to commit to RE100, EP100 and EV100 (first triple joiner) – showing real business leadership in the clean energy transition by taking a joined-up approach.
