Abstract

The preparation process of CO₂ mineralized sealing cementitious materials for carbon neutrality targets utilizes industrial by-products and mineral raw materials to achieve efficient carbon fixation and resource conversion. This process demonstrates unique advantages in microstructure regulation, enabling the formation of stable carbonate minerals within the cementitious system that enhance mechanical properties and durability while reducing carbon emissions. Through rational selection of raw materials and reaction conditions, the carbon sequestration process achieves synergistic coupling with cementitious reactions, delivering both environmental benefits and engineering value. This technology pioneers new pathways for developing alternative cement substitutes and provides crucial support for achieving carbon peaking and neutrality strategies.
