ABSTRACT:
The present invention is directed to a dry phosphate cement mixture and process for manufacture of same. The dry mixture includes at least Al(H.sub.2 PO.sub.4).sub.3, a group IIA metal bonded to oxygen, and an aggregate. The process for manufacturing cement includes associating the dry reagent with a substantially polar solvent, such as water. The total reagent concentration is formulated such that only nominally exothermic reactions are observed. The process accommodates variable setting times and provides resulting concrete which exhibits formidable structural integrity.
