USE - Used as de-noising heat insulating cement mortar. ADVANTAGE - The mortar has good heat preservation effect, resistance to abrasion and chemical, has high strength, high impact strength, good ductility and construction convenience. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the de-noising heat insulating cement mortar comprising (i) calcining 1/3 of phosphogypsum at 165-170 degrees C for 2-4 hours, aging for 4-5 days to obtain beta -hemihydrate gypsum, heating the calcined phosphogypsum at a temperature of 345-355 degrees C for 3-4 hours to obtain type II anhydrite, then mixing beta -hemihydrate gypsum and type II anhydrite to obtain building gypsum; and (ii) mixing portland cement, carbon fiber-graphene reinforcing agent, re-dispersible emulsion powder, ethyl acetate and water to obtain mixture, then adding the mixture of building gypsum, stirring at 200-300 rotations/minute of rotating speed for 40-50 minutes to obtain slurry, then adding remaining raw materials into the slurry at a stirring speed of 100-150 rotations/minute for 1-2 hours.
