Abstract
A mixture for making a high strength phosphate cement includes monopotassium phosphate, a Group IIA metal oxide in amounts of about 20 to about 100 parts per 100 parts of the monopotassium phosphate and monocalcium orthophosphate in amounts of from about 3 to about 30 parts per 100 parts of the monopotassium phosphate. Products made from the phosphate cement have a pH of less than about 9 and the product develops a compressive strength greater than 2000 psi in 24 hours.
