Title: Towards amine-based CO2 capture in cement-based materials

This research aims to enhance CO2 sequestration in cement-based materials by integrating amines, which are organic compounds with nitrogen atoms capable of bonding with CO2. The study examines how these amines improve CO2 capture within essential hydrated phases like portlandite and Calcium-Silicate-Hydrate (C-S-H). Findings indicate that amines significantly accelerate CO2 mineralisation, leading to notable microstructural changes and increased calcite formation. By advancing the development of sustainable construction materials, this work positions buildings to function as "synthetic trees," offering an innovative approach to reducing atmospheric CO2 and mitigating global warming.
