A method for improving sheet stiffness of paper is disclosed, as well as a calcium silicate hydrate mixture useful in such a process. The paper is manufactured by drying a furnish mixture of an aqueous pulp slurry and preselected fillers, the method involving incorporating into the furnish mixture particles of multiple phase calcium silicate hydrate comprising a major component comprised of riversideite and a minor component of xonotlite. The particles have an irregular globular structure, typically with an outside diameter from about 10 to about 30 microns.
