Unitized cement admixture

A process for preparing a cementitious mixture including

• a) providing at least one cementitious composition and a liquid,
• b) at least partially mixing the cementitious composition and the liquid;
• c) introducing at least one admixture material to the at least partially mixed cementitious composition,
• wherein the at least one admixture material comprises at least one compacted unit of an amount of said admixture material, said unit characterized by having strength sufficient to maintain structural integrity during handling and storage, but having at least one of sufficient solubility and sufficient friability upon mechanical agitation within a wet mixing environment of a cementitious composition mixture to at least one of dissolve and fragment for uniform dispersal throughout the cementitious composition mixture, and
• d) mixing the at least partially mixed cementitious composition and the at least one compacted unit to at least one of dissolve and fragment the at least one compacted unit to substantially disperse the admixture material throughout the cementitious composition.
