LC3 concrete is rapidly gaining acceptance across a diverse range of construction applications, demonstrating that low-carbon materials can deliver the performance required for critical infrastructure. From the first LC3 concrete road in India to large-scale airport construction and soil stabilization, LC3 is proving its versatility and reliability.

LC3 in Pavement and Road Construction

India's First LC3 Concrete Road
Lodha became the first real estate developer in India to deploy LC3 concrete for road construction at Palava City. This innovation reduces carbon emissions by up to 40% compared with conventional cement while offering enhanced long-term durability and strength.

Roller-Compacted Concrete Pavements
Research has demonstrated the use of LC3 as a partial replacement for ordinary Portland cement in roller-compacted concrete pavements (RCCPs), offering a green approach to pavement construction.

Soil Stabilization
LC3 shows significant potential in soil stabilization for applications in roads and pavements construction.

LC3 in Large-Scale Infrastructure

Noida International Airport
Noida International Airport (NIA) became the first large-scale project in India to utilize LC3. LC3 was used extensively in the construction of the airport. The project demonstrates how major infrastructure projects can lead the change and set a new standard for the future of construction.

LC3 in Structural Concrete

Structural Lightweight Concrete
Research has explored producing sustainable structural lightweight concrete based on LC3 using waste from construction and demolition. Crushed brick powder can replace metakaolin, and recycled concrete powder can replace limestone powder.

High-Strength Concrete
Studies have shown that concrete grades C50 and C60 can be achieved with LC3 mixes, providing satisfactory durability and reliability.

Marine and Aggressive Environments
LC3 has demonstrated excellent durability in aggressive environments with low chloride permeability (100–2000 Coulombs). Calcined clay-cement combinations can achieve good chloride migration resistance.

LC3 Performance in Concrete

Mechanical Properties
LC3 achieves compressive strengths exceeding 40 MPa and effectively reduces porosity by up to 28%.

Durability
LC3 concrete offers enhanced strength and durability with lower greenhouse gas emissions. LC3 concrete has a 19% reduction in CO₂ emissions compared to OPC concrete.

Service Life
LC3 concrete can provide a service life of more than 120 years under various exposures.

UNIDO Guidance

The United Nations Industrial Development Organization (UNIDO) has published "LC3: A Guide to Best Practices for Scalable, Affordable, and Sustainable Low-Carbon Building," covering the full value chain—from raw material selection to cement production and concrete performance.
