Abstract: The present disclosure relates to improved methods for producing a low CO2 cement composition. Disclosed herein are methods for producing a cement composition comprising mixing reactants comprising a reactive powder, an activator, and a retardant in the presence of water, followed by the mixing of an accelerator into the reactants, and allowing the reactants to react to form the cement composition.
