The carbon mineralization behavior of wollastonite and its impact on pozzolanic reactivity
Original language description
Carbonation treatment of silicate minerals can achieve the dual purposes of carbon capture and enhancing the pozzolanic reactivity. This study introduced a wet grinding carbonation method to efficiently carbonate wollastonite and examined its carbonation behavior and pozzolanic activity evolution through this process. The results demonstrated that wet grinding carbonation method offers significant advantages over the traditional direct aqueous carbonation method. Complete carbonation of wollastonite was achieved within merely 6 h, with a CO2 sequestration efficiency reaching 29.8 g/100 g of wollastonite. The carbonation products of wollastonite exhibited a microstructure characterized by amorphous SiO2 coating calcite. Mortar specimens incorporating 20 % carbonated wollastonite exhibited 28 d compressive strength surpassing that of the cement mortar. This work not only provides a method for efficient carbon sequestration of silicate minerals but also offers a way for the high-value utilization of industrial solid waste.
