ABSTRACT:
An apparatus for making a cementitious composition may comprise a grinding mill for producing a cementitious composition from clinker and gypsum and classifiers for separating the cementitious composition into various portions. A primary portion of the cementitious composition has a particle size distribution such that substantially all of its particles are of a size of about 10 microns or smaller. A secondary portion and a remainder portion of the cementitious composition are combinable to form a resultant cementitious composition selected from Type I portland cement and Type III portland cement.
