(57) A process for preparing supplementary cementitious materials (SCMs) involves milling silica-based feedstocks in a carbon dioxide (COz)-rich environment. In particular, the process includes providing a silica-based feedstock Providing a silica-based feedstock in an aqueous solution within a milling apparatus in an aqueous solution within a milling apparatus, and introducing CO2 into the aqueous solution before or during milling. The process transforms the feedstock into a microstructurally activated, passive CO, sequestering component that can be used as SCMs in cement mixtures.
