Portland cement particles coarser than 30 microns never completely hydrate, serving no other purpose than expensive fine aggregate; replacement of coarse clinker grains in cement with some other suitably graded unburnt and cheaper material, would be advantageous; test data on "blended cement," in which 30% of chalk-flint mixture was added to very finely ground clinker gypsum.
