About
EcoFast Concrete reduces emissions by replacing up to 80% of cement with natural substitutes like limestone, combined with specially formulated chemical admixtures that accelerate hardening. Unlike conventional solutions, it meets industrial productivity requirements while significantly lowering carbon impact. This innovation addresses one of construction’s toughest trade-offs: sustainability versus speed. Successfully validated at lab scale, the solution enables early demoulding and faster project delivery, offering a scalable path toward decarbonising concrete without compromising performance

I am a Civil Engineer at ETH Zurich with a background in both practice and research. After earning my Bachelor's degree and gaining a year of industry experience, I returned to ETH to pursue a Master of Science in Civil Engineering, focusing on advancing expertise in concrete and material science through a range of specialized courses. Alongside my studies, I have been part of Calspak since its inception, contributing to the development of ultra-low-carbon cement. My key areas of interest include low-CO₂ concrete, hydration control, and structural engineering.
