1. A method for designing a cement composition comprising:
providing a target compressive strength and a target composition density;
selecting at least one cementitious material from a plurality of cementitious materials;
calculating a required amount of water to produce a cement composition with the target composition density, the cement composition comprising the water and the at least one cementitious material;
calculating a compressive strength of the cement composition based at least in part on a model of compressive strength wherein the model of compressive strength includes a component of reactivity index for each cementitious material in the cement composition;
comparing the calculated compressive strength to the target compressive strength; and
preparing the cement composition with the calculated compressive strength.
