C3s To C2s Ratio For Better Cement Grinding

  • Bogue calculationUnderstanding Cement

    The standard Bogue calculation refers to cement clinker rather than cement but it can be adjusted for use with cement Although the result is only approximate the calculation is an extremely useful and widely used calculation in the cement industry The calculation assumes that the four main clinker minerals are pure minerals with compositions
