FIELD: chemistry.
SUBSTANCE: invention relates to raw material mixture for obtaining phosphate product, phosphate-based cement suspension and to method for obtaining phosphate product. Mixture for obtaining highly-strong phosphate cement includes potassium dihydroorthophosphate, oxide of group IIA metal in quantity from approximately 20 to approximately 100 parts per 100 parts of potassium dihydroorthposphate and calcium dihydroorthposphate in quantity from approximately 3 to approximately 30 parts per 100 parts of potassium dihydroorthposphate. Product, manufactured from said phosphate cement, has pH approximately 7-9, and said product develops compression strength higher (13.5 megapascals) 2000 lbs/sq. inch within 24 hours. Invention is developed in dependent items of invention formula.
EFFECT: increased accuracy of product from mixture with pH 7-9 at seven-day age.
