1. A method of designing a cement for use in a wellbore comprising:
obtaining a target Young's modulus and a density;
calculating a compressive strength requirement using the target Young's modulus and the density as an input;
classifying a plurality of solid particulates based on physicochemical properties of the solid particulates, wherein the solid particulates are classified by an oxide analysis and a water requirement analysis;
calculating a reactive index for at least two of the solid particulates;
designing a cement composition by selecting two or more solid particulates from the plurality of the solid particulates, wherein the designed cement composition meets the calculated compressive strength requirement;
testing the designed cement composition for compressive strength and Young's modulus; and
confirming the designed cement composition meets or exceeds the Young's modulus target.
