1. A method of sequestering carbon dioxide (CO2), the method comprising:
producing a gas comprising CO2;
separating CO2 gas from the gas comprising CO2;
preparing a cement slurry comprising water, at least a portion of the CO2 gas, and a cement composition comprising a hydraulic cement material, a latent-hydraulic cement material, and a non-hydraulic cement material, wherein the cement composition from about 20 to about 80 weight percent (wt %) of the hydraulic cement material, from about 10 to about 60 wt % of the latent-hydraulic cement material, and from about 10 to about 60 wt % of the non-hydraulic cement material, based on a total weight of the hydraulic cement material, the latent-hydraulic cement material, and the non-hydraulic cement material;
placing the cement slurry downhole via a wellbore; and
allowing the cement slurry to harden to provide a hardened cement.
