Cement Composition And Its Relation With Compressive Strength

A system comprising:

• a predictive model database comprising at least one model of compressive strength for a plurality of cementitious materials;
• and
• a computer system configured to:
• accept an input of compressive strength and composition density;
• query the predictive model database and select a model;
• generate a cement composition, based at least in part on the selected model, compressive strength, and composition density;
• and
• display the cement composition to a user.

A non-transitory computer readable medium having data stored therein representing software executable by a computer, the software including instructions comprising:

• instructions to accept a target compressive strength and a target composition density;
• instructions to select one or more cementitious materials from a list of a plurality of cementitious materials to produce an initial cement composition;
• instructions to calculate an amount of water required to produce a cement composition with the target composition density, where the cement composition comprises the water and the initial cement composition;
• and
• instructions to calculate a compressive strength of the cement composition based at least in part on a model of compressive strength where the model of compressive strength is a function of w/ceff and where the cement composition includes the initial cement composition and the amount of water.
