NOVELTY - Preparing cement mortar involves putting 6-8 pts. wt. graphene oxide into 80-120 pts. wt. water for ultrasonic dispersion to obtain a graphene oxide dispersion, and adding 13-17 pts. wt. of basalt fiber to graphene oxide dispersion, and after keeping rotating speed constant, stirring and mixing, and obtaining mixed solution of graphene oxide and basalt fiber. The mixed solution of graphene oxide and basalt fiber is heated to obtain graphene basalt fiber. The graphene basalt fiber is added into stirring pot, and added sand, cement, polycarboxylic acid water reducing agent, potassium aluminosilicate, anisene-maleic anhydride copolymer, lysine calcium phosphate, chromium trichloride hexahydrate are heated and stirred to produce cement mortar. The weight ratio of potassium aluminosilicate, anisene-maleic anhydride copolymer, lysine calcium phosphate, and chromium trichloride hexahydrate is (7-12):(2-4):(18-26):(3-6). USE - Method for preparing cement mortar. ADVANTAGE - The method enables to prepare cement mortar, that has better compressive strength and flexural strength of the mortar specimen.
