Welcome to PRECAST-CO₂
The PRECAST-CO₂ project is focused on developing innovative alternatives for CO₂ capture and utilization (CCU) to reduce the carbon footprint of non-structural precast concrete elements. By implementing sustainable technologies, we aim to contribute to climate change mitigation and promote a circular economy in the construction industry.
Our multidisciplinary research team, from the University of Córdoba, is working to integrate CO₂ capture into new materials for construction, making the industry more efficient and environmentally friendly.
Join us on this journey toward a more sustainable future!
The Project
SUMMARY
PRECAST-CO₂ explores six complementary approaches to capture and utilize CO₂ in the production of precast concrete elements:
- Development of new reversible CO₂ adsorbents to reduce emissions from cement and energy production.
- Use of irreversible CO₂ adsorbents incorporated into concrete as carbon sinks.
- CO₂ curing and carbonation of precast products to improve material properties and sustainability.
- Integration of recycled aggregates from construction and demolition waste (CDW), which have a higher carbonation capacity than natural aggregates.
- Substituting cement with non-conforming fly ash (Nc-FA) from thermoelectric power plants, reducing cement consumption.
- Utilization of carbonated water in concrete mixing, accelerating setting time and enhancing mechanical performance.
This project aligns with the 2017-2020 State Plan for Scientific and Technical Research and Innovation and the Horizon 2020 program, providing solutions for climate change mitigation and resource efficiency in construction.
