A pozzolan-modified portland cement composition containing the present invention's composition inter-ground or inter-blended with a portland cement. The pozzolan-modified portland cement contains portland cement, ultra-fine fly ash, calcined kaolin, fused silica, and a cellulose ether derivative. An admixture, additive, or addition, based on the present invention's composition, inter-ground or inter-blended into portland cement to create such pozzolan-modified portland cements.
