Abstract: A method for preparing a construction material for a roadbed and a pavement by using construction solid waste-based geopolymers includes: preparing a construction solid waste-based geopolymer cementitious material and construction solid waste-based recycled sand by using construction solid wastes, and then preparing the construction material by batching, stirring, molding, and curing the cementitious material and the recycled sand with aggregates and water. Barium hydroxide is determined as a main activator and a high-pressure activation is performed, thereby promoting a dissolution efficiency of active silicon and aluminum in the construction solid wastes; and a compensator is added to promote polymerization to obtain the cementitious material with a compact three-dimensional network structure. The recycled sand is also obtained, and the construction material is obtained by using the recycled sand and the cementitious material, thereby fully utilizing the construction solid wastes and improving preparation efficiency of the construction material.

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.
