In August 2024, specialists from Grupo Sofonias and Red Ecosur conducted a consultancy in Mexico focused on the implementation of LC3 cement, a material that contributes to reducing CO2 emissions. This initiative was carried out in collaboration with Habitat for Humanity Mexico and Holcim Mexico, aiming to build sustainable housing and reduce the environmental impact of the construction process.
Model Housing and Material Testing The consultancy included the construction of a pilot house in the community of Chilapilla, Veracruz, using calcined clay cement, an eco-friendly alternative that reduces CO2 emissions by up to 40% compared to conventional cement. This house, covering 45.63 m², used approximately 12.5 m³ of concrete and 6 m³ of mortar, resulting in significant emission savings. During the project, over 240 concrete samples were produced and extensive testing was carried out under Mexican and ASTM standards to ensure the quality and durability of LC3 cement.
Training and Knowledge Exchange In addition to the technical tests, the team led an awareness and training session aimed at bricklayers, engineers, and project collaborators. The benefits of LC3 cement were highlighted, including its workability, low heat emission during setting, and resistance to cracking. Despite the inclement weather, participants showed great interest in the features and benefits of the new material.
The project also included a webinar organized by CITEC, where over 150 construction industry professionals discussed decarbonizing the industry through the use of calcined clays.
Future Prospects The first results of the study will be available in October 2024, and it is expected that they will confirm the viability of LC3 cement as a sustainable alternative in construction. The success of this first phase opens the door to future collaborations between Grupo Sofonias, CIDEM, and Holcim Mexico, with the goal of continuing to develop solutions that mitigate climate change and promote the construction of dignified and sustainable housing in vulnerable communities.
This project represents an important step towards decarbonizing construction in Latin America, aligning with global goals to reduce CO2 emissions by 2050.
