Abstract: The present disclosure relates to methods that transform high salinity brine into a non-toxic, CO2-absorbing cementitious aggregate composition and a lower salinity water component which can each be recycled to the desalination facility, further processed to produce fresh water, and/or added to a body of water and without harming the local flora and fauna. The present disclosure provides methods comprising steps of: (a) combining (i) a high salinity brine, (ii) CO2, and (iii) a pozzolan and/or a latently hydraulic material; and (b) permitting the combination obtained in step (a) to persist under conditions sufficient to transform the combination into a cementitious aggregate composition and a reduced salinity water component. In some case, an activator, as disclosed herein, is added to the combination. The present disclosure further a cementitious aggregate compositions and shaped cementitious compositions, each obtained by herein-disclosed methods.
