Abstract: A process produces a paste with improved workability. At least 30% by volume of the paste when cured under ASTM conditions crystallizes into monolithic crystals of calcium silicate hydrate exhibiting a unique crystalline structure and having improved compressive strength.
Abstract: A paste with improved workability is formed from at least 20% Portland cement. The paste when cured under ASTM conditions crystallizes into a substantially homogeneous mass of monolithic crystals of calcium silicate hydrate exhibiting a unique crystalline structure and having improved compressive strength.
Abstract: A rotary mill to colloidalize a premixed mortar in a high energy manner so as to increase the degree of hydration comprising a hollow collector casing having a feed inlet to receive the premixed mortar and a discharge outlet for the mixed product, a pair of counterrotating members cooperatively forming a shear zone therebetween wherein the shear zone comprises an inlet region to receive the premixed mortar from the feed inlet, a convergency region to impart a high energy shear to the premixed mortar and an expanding discharge region to feed the premixed mortar to the discharge outlet, and a drive and drive train coupled to the counterrotating members to impart rotational movement thereto.
