Abstract:
1. An apparatus for making a cementitious composition comprising: a first flow line configured to receive a first stream of Type I portland cement; a diverter disposed along said first flow line; a second flow line downstream from said diverter; said diverter configured to remove a scalped portion from said first stream of Type I portland cement and direct the scalped portion along said second flow line; said diverter configured to direct a remainder portion of said first stream of Type I portland cement to a downstream portion of said first flow line; said second flow line configured to route said scalped portion from said diverter to a classifier; said classifier adapted for receiving said scalped portion and separating said scalped portion into a primary portion and a secondary portion; a first storage silo connected to said downstream portion of said first flow line; a third flow line connected to said classifier and configured to route said secondary portion to said first storage silo; said first storage silo adapted for receiving said secondary portion and said remainder portion of said first stream of Type I portland cement; a second storage silo adapted for receiving said primary portion; and a fourth flow line connected to said classifier and configured to route said primary portion to said second storage silo; wherein said primary portion has a particle size distribution such that substantially all of its particles are of a size of about 10 microns or smaller; wherein said secondary portion and said remainder portion are combinable to form a resultant cementitious composition; wherein said resultant cementitious composition is selected from Type I portland cement and Type III portland cement.
