NOVELTY - Preparing graphene oxide reinforced cement-based mortar material comprises (1) adding graphene oxide to deionized water and performing ultrasonic dispersion in ultrasonic cleaner to obtain graphite oxide, (2) immersing graphene oxide dispersion in liquid nitrogen for rapid cooling to form ice cubes, (3) oxidizing graphite under low temperature conditions, mechanically crushing olefin dispersion ice cube in stirring pot, where the large ice cubes are broken into small ice balls by low-speed stirring, adding standard sand, stirring and mixing the standard sand and graphene oxide dispersion ice cubes, molding until small ice cube melts to obtain graphene-reinforced cement-based mortar material, (4) placing in standard curing box for curing, the standard curing box temperature is 20 degrees C and relative humidity is greater than or equal to 95%, after 1 day of curing, removing mold and the maintenance is continued in the curing tank to the test age. USE - The method is useful for preparing graphene oxide reinforced cement-based mortar material.
