An additive for concrete, mortar or grout comprises at least one admixture material in a compacted unit of selected amount, the unit having strength sufficient to maintain structural integrity during handling and storage, but having sufficient solubility or friability upon mechanical agitation within a wet mixing environment of a cementitious composition mixture to dissolve or fragment for uniform dispersal throughout the cementitious composition mixture. A process for preparing a cementitious mixture includes providing ingredients i) at least one cementitious composition, ii) at least one admixture material and iii) a liquid; wherein the admixture material comprises at least one compacted unit having strength sufficient to maintain structural integrity during handling and storage, but having sufficient solubility or friability upon mechanical agitation within a wet mixing environment of the cementitious mixture to dissolve or fragment for uniform dispersal throughout said cementitious mixture; combining ingredients i), ii) and iii) and mixing in any order to dissolve or fragment the compacted unit to substantially disperse the admixture material throughout the other ingredients.
