TITLE Phosphate Cement for High-Strength Cement-Like Products ABSTRACT OF THE DISCLOSURE Rapid-setting compositions based on MgO and Al(H2PO4)3 and having at least a ten-minute working time, and thus suitable for mortars and road patching, form concrete-like products having increased compressive strength when fly ash is present. Fly ash reacts with aluminum phosphate to form a cementitous composition whose compressive strength is the cause of the strength increase observed in the MgO/Al(H2PO4)3 reaction product. PI-0406 35
