         47 . The method of  claim 43 , wherein the composition comprises between 0.001-10% w/w aragonite seed, inorganic additive or organic additive. 
     
     
         48 . The method of  claim 43 , wherein the facilitating the aragonite formation results in one or more of better linkage or bonding, higher tensile strength, or higher impact fracture toughness, after cementation of the composition. 
     
     
         49 . The method of  claim 43 , wherein the composition after combination with water, setting and hardening has a compressive strength in a range of 14-40 MPa. 
     
     
         50 . The method of  claim 43 , wherein the composition is a precipitate, slurry, or a dry powder. 
     
     
         51 . The method of  claim 43 , wherein the cement is a formed building material selected from the group consisting of masonry unit, brick, block, tile, construction panel, cement board, fiber-cement siding, drywall, conduit, basins, beam, column, concrete slab, acoustic barrier, insulation material, and combination thereof. 
     
     
         52 . The method of  claim 43 , wherein the composition has an average particle size of between 0.1-100 microns. 
     
     
         53 . The method of  claim 43 , further comprising contacting CO 2  from a CO 2  source with a solution comprising proton removing agent and alkaline earth-metal ions under one or more conditions to make the composition. 
     
     
         54 . The method of  claim 53 , wherein the one or more conditions are selected from the group consisting of mixing, stirring, temperature, pH, precipitation, residence time of the precipitate, dewatering of precipitate, washing precipitate with water, ion ratio, concentration of additives, drying, milling, grinding, storing, aging, and curing. 
     
     
         55 . The method of  claim 53 , wherein the one or more conditions comprise having ratio of calcium to carbonate during formation of the activated vaterite to be between 1:1 to 1.5:1. 
     
     
         56 . The method of  claim 43 , further comprising activating the composition by thermal activation, mechanical activation, or combination thereof.
