Utilization of 7.15 tonnes of eLM Zero in 135 m³ of concrete

Storage of 15 tonnes of atmospheric CO₂

Crafted by: Max Bögl

Date: August, 2025

Location: Tauernfeld, Germany

‍

In an innovation partnership, Max Bögl created foundation slabs at their construction facility in Tauernfeld using ecoLocked Materials®. By incorporating CEM III/A, a highly clinker-reduced cement, in their mix design, they already reduced the carbon footprint of their concrete. This effect was further enhanced by adding over 7 tonnes of eLM Zero into 135 m³ of concrete, permanently storing 15 tonnes of atmospheric carbon and producing a CO₂-neutral concrete, all while maintaining excellent workability, durability, and technical performance.

Beyond carbon storage, the project provided valuable insights into the technical benefits of eLM, including reduced concrete weight, exceptional flow behavior, and high stability against segregation. The installation of the in-situ concrete slab in August 2025 demonstrated the practical viability of CO₂-neutral concrete under real-world construction conditions.

This collaboration showcases the potential of combining innovation and partnership to transform the construction sector. By integrating CO₂-negative materials, Max Bögl and ecoLocked are paving the way for sustainable, high-performance concrete that turns buildings into permanent carbon sinks.
