Emerging CO2 utilization technologies for construction materials: A review

The construction industry is a major contributor of CO 2 emissions. Carbonation, involving the reaction with alkaline reactants, immobilizes into thermodynamically stable carbonates used in materials such as concrete and aggregates. utilization considered one most promising routes for carbon sequestration, $400 billion market opportunity potential to reduce annual emissions by up 3 Gt 2030. This paper reviews current status from perspective scientific research commercial applications. explanation fundamental carbonation mechanisms was extended cover different binder systems Portland cement, non-hydraulic calcium silicate, industrial solid wastes magnesium-based materials. Factors affecting kinetics properties final products were reviewed. Furthermore, state initiatives production various building components presented. Finally, key issues regarding challenges faced scaling technologies academia, relevant regulatory bodies highlighted. Recommendations address dilemma promote large-scale application development provided. • Utilization route sequestration. Current setups Carbonation traditional novel are discussed. Key academic perspectives increased
