A hydraulic binder including (in % by dry weight); A. at least 50 of at least one ground and granulated blast-furnace slag; B. more than 5 of at least one calcium aluminate cement and/or of at least one calcium sulfoaluminate cement; C. more than 5 of at least one source of sulfate ions; D. between 1 and 5 of Ca(OH).sub.2 and/or Portland cement; E. between 0.01 and 1 of at least one alkali metal carbonate; F. and at least one alkalifying reagent consisting of at least one alkali metal carbonate and/or bicarbonate, different from E; under the following conditions: (i) amount of C allows sulfate ions of C to react with B and A; (ii) the amount of F sufficiently causes a reaction with D in water resulting in a wet formulation with a pH not less than 12, for a water-to-mortar mixing rate between 10 and 35% by weight.

A manufacturing process of a concrete product includes: (1) extracting calcium from solids as portlandite; (2) forming a cementitious slurry including the portlandite; (3) shaping the cementitious slurry into a structural component; and (4) exposing the structural component to carbon dioxide sourced from a flue gas stream, thereby forming the concrete product.

Aqueous cementitious slurries including predominantly Type I Portland cement containing an aluminate additive. The aluminate additive is an aluminate salt other than calcium aluminate or calcium sulfoaluminate, preferably sodium aluminate. Cementitious reactive powders of the slurry include the Type I Portland cement and 0.1-10 wt. % of the aluminate additive as an accelerator. The slurries may have a set time of about 10 minutes or less. Due to the short set time, the cementitious reactive powders may facilitate cement board fabrication by continuous manufacturing processes. Methods for making cement boards may include disposing the aqueous cementitious slurry including the cementitious reactive powders in a continuous layer, preferably upon a porous support, and setting the aqueous cementitious slurry with a set time of about 10 minutes or less.
