Whether it’s about e-vehicles or organic farming, the whole world is moving towards eco-friendly and sustainable choices. However, even in this transition, one challenge remains constant: the environmental impact of traditional cement.
The Ordinary Portland Cement (OPC) production is responsible for nearly 8% of global CO₂ emissions. Many companies have made partial progress through the use of blended cement and other construction materials. Still, the industry was lacking a truly clinker-free, environmentally friendly cement until the launch of Navocem.
Why Green Clinker-Free Cement Matters
Before we introduce you to Navocem’s Alkali clinker-free cement, let’s quickly take a look at why it matters:
- OPC or the traditional cement is produced through an energy-intensive process involving limestone calcination and clinker grinding.
- The process alone is responsible for ~660 kg of CO₂ per tonne of cement, contributing up to 8% of global CO₂ emissions.
- Additionally, the high capital investment in traditional cement plants only compounds the challenge.
Introducing Navocem: India’s First 100% Clinker-Free Cement
The above-mentioned challenges of OPC made it essential for the construction experts to discover a clinker-free cement.
Discovery
Founded by Dr. Ramkumar Natarajan, a materials science engineer with a Ph.D. from the University of Illinois and postdoctoral work at Argonne National Lab (USA), Navocem was established to deliver sustainable and high-performance cement solutions.
After a decade long research, Dr. Ramkumar discovered multiple patents, including a proprietary method to produce 100% clinker-free cement, with the same name as the brand Navocem.
How It Is Developed
Navocem, the affordable cement for construction, is developed from:
- 90–94% GGBFS (Ground Granulated Blast Furnace Slag), which is a by-product of the steel industry.
- A proprietary low-energy activator.
- Zero clinker or limestone calcination.
Benefits of Navocem Green Clinker-Free Cement
As a green construction cement, Navocem bridges the gap between sustainability, performance, and affordability. Here are the key benefits of Navocem.
-
Environmental Edge
Navocem not just partially substitutes clinker, but completely eliminates it, making it truly India’s first green cement. Navocem supports the environment by reducing:
- CO₂ emissions by approximately 80%
- Energy and fuel consumption required in clinker production
- Dependence on fossils, like limestone
-
Circular Economy
By repurposing steel industry waste GGBFS, Navocem supports the circular economy. This reduces the waste and pollution, promoting sustainability.
-
Superior Strength and Durability
Despite being clinker-free, Navocem outperforms the traditional OPC 43 cement in compressive strength. Here are the results from an independent test:
| Age | OPC 43 Grade | Navocem Green Cement |
| 3 Days | 23 MPa | 30 MPa |
| 7 Days | 33 MPa | 38 MPa |
| 28 Days | 43 MPa | 47.5 MPa |
-
Better Performance and Longevity
Beyond compressive strength, Navocem’s green and affordable cement for construction also ensures better performance by:
- Exhibiting 30% higher durability in extreme weather
- Reducing the probability of shrinkage and cracks
- Longer lifespan of buildings in chloride or sulphate-rich regions
-
Conforms to Indian and International Standards
Though Navocem is a relatively new and innovative construction approach, the cement complies with the necessary Indian and International standards. It conforms to:
- IS 17452:2020 – Alkali Activated Concrete for Precast Products
- ASTM C1157 – Performance Standard for Hydraulic Cement
This ensures the safety and efficacy of the green cement for all public and private projects, including precast, Pavement Quality Concrete (PQC), and structural concrete.
-
Reduced Water Permeability
Navocem’s green cement has lower water permeability than traditional cement. In simple words, after completion, less water can seep in through the buildings and walls. Results? Better structural integrity and protection of embedded steel reinforcement.
-
Versatile Applications
The unique and competitive edge of Navocem makes it the best clinker-free cement for all kinds of constructions:
- The low heat of hydration reduces thermal stress and prevents early-age cracking. This makes it perfect for mass pours like dams, bridges, and foundations, and hot weather concreting.
- It gains strength faster, which makes it ideal for non-structural projects like concrete blocks, pavers, roads, retaining walls, plastering, and fencing.
- Navocem’s green clinker-free cement is more chemically resistant than OPC. It fits better in chemically aggressive projects like coastal infrastructure, sewage systems, and marine structures.
-
Real World Applications
If you are thinking Navocem’s cement is ideal just in theory, you might be taking it pretty wrong. Additionally, our cement has also undergone rigorous lab testing at IIT Jodhpur. It confirms its versatility, strength, and durability. Currently, practical trials are going on to explore its wider structural applications.
