LC3 Technology Resource Center For Latin America In Cuba

Connecting Scientific Research, Cement Industry and Low-Carbon Innovation Across Latin America

The overall objective of the LC3 Technology Resource Center is to contribute to the fight against climate change by introducing a greener cement technology in Latin America. This is achieved through technical assistance to cement producers and the development of mechanisms that make production economically viable and successful.

Low-Carbon Cement: LC3 Technology

LC3 (Limestone Calcined Clay Cement) is an innovative blend of Portland cement that incorporates calcined kaolinitic clay and up to 15% additional limestone.

Clay and limestone are widely available around the world, with abundant reserves. When activated clay and limestone are combined with Portland cement, they create a synergistic reaction that allows up to 50% of the clinker — the traditional main component of cement — to be replaced.

LC3 maintains the mechanical performance of conventional cement while offering significant environmental and economic advantages. Its production costs are lower and it generates between 25% and 40% fewer carbon emissions during manufacturing.

This technology has the potential to reduce global CO₂ emissions by approximately 500 million tonnes per year.

An international team based in Switzerland, Cuba and India guides the implementation of this technology in collaboration with the cement industry. LC3 has successfully moved from laboratory research to industrial-scale trials and practical construction applications. Extensive testing of samples exposed to extreme environmental conditions over several years has produced positive results.

The LC3 Technology Resource Center (LC3-TRC) for Latin America

The LC3 Technology Resource Center was established in Cuba to serve as a bridge between industry and academia, accelerating the introduction of new LC3 developments throughout Latin America.

The Center provides environmentally friendly solutions for medium-sized and large companies in the construction sector, drawing on scientific knowledge and practical experience. It consolidates the results of twenty years of research and practical application in collaboration with cement companies.

The Center has highly qualified personnel and comprehensive laboratory facilities based at the Central University of Las Villas in Cuba. These facilities include a state-of-the-art production plant with a capacity of up to 12 tonnes per day.

The LC3-TRC maintains close links with the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland and is part of its research program funded by the Swiss Agency for Development and Cooperation (SDC).

Research, Testing and Construction Applications in Cuba and India

In recent years, extensive testing has been carried out alongside scientific research and the construction of several structures in India and Cuba.

In Cuba, a coastal testing site has been established to study the long-term durability of LC3 concrete. Concrete blocks made with LC3 are exposed to harsh marine conditions to evaluate their performance.

After five years of exposure, the results have been excellent. In general, the green concrete has demonstrated greater durability than conventional concrete.

These findings reinforce the potential of LC3 as a reliable alternative for reducing the environmental footprint of the construction industry.

Expanding LC3 Technology Worldwide

Several major cement companies in Latin America have contracted the Technology Resource Center to assess their raw materials and evaluate the economic feasibility of LC3 production.

At the time of the original publication, preparations for commercial production were underway in four countries. However, these initiatives represented only a small part of the potential for reducing the cement industry's environmental footprint across the continent.

The Center's vision is to provide practical responses to the growing demand for climate change mitigation through the application of advanced and proven technologies.

More recently, African cement companies have also contracted the Center to evaluate their potential for LC3 production. Its impact is growing as the global cement industry faces increasing pressure to reduce CO₂ emissions.

The LC3-TRC works with cement producers of different sizes, including large, medium-sized and small companies. The original program anticipated the first commercial production in two companies in Latin America and Africa in 2020.

Financing and Cooperation

The program operates through an innovative financing model based on public-private partnerships.

The Technology Resource Center has invested in laboratories, advanced production facilities, and education and training personnel.

Interested cement companies contract the Center and cover the direct costs of raw material testing and the formulation of potential raw material blends.

This model connects scientific research with industrial needs, helping companies evaluate the technical and economic viability of adopting LC3 technology.

Building a Low-Carbon Future for Cement

The LC3 Technology Resource Center in Cuba represents an important link between scientific research, industrial innovation and sustainable construction.

By connecting research institutions, cement producers and international cooperation partners, the Center supports the development and transfer of low-carbon cement technology across Latin America and beyond.

Its work demonstrates how locally available resources, scientific knowledge and practical industrial collaboration can contribute to reducing emissions while maintaining the performance and durability required by the construction sector.
