Abstract：Cement-based materials can quickly form carbon sequestration products mainly composed of carbonates and high polymerization silica gels through carbonization reaction.Carbon sequestration products have received widespread attention due to their ability to balance CO2 absorption and mechanical properties.Based on the development of raw materials,composition and pro-cess optimization,and maintenance systems design,domestic and foreign research teams have developed various applications,mainly including boards,blocks,aggregates,etc.This article started from the mechanism and kinetics of carbonation,summarized the influ-ence of reaction conditions on structure and products composition.The types,properties,and application of existing products were also concluded,in order to provide new ideas for carbon reduction in the construction and building materials industry.
