▎ 摘  要

NOVELTY - Preparing graphene concrete involves mixing one or two of graphene and graphene oxide with a dispersant and a co-dispersant, and adding water for pre-dispersion, where the stirring speed in pre-dispersion is 100-200 revolutions/minute. The temperature is 10-20 degrees C, the stirring time is 15-30 minutes, and the pre-dispersed liquid is prepared. The ultrasonic dispersion is performed on the pre-dispersed liquid, and the ultrasonic power is 3000-6000 watts, ultrasonic stirring speed is 50-100 revolutions/minute, ultrasonic temperature 30-50 degrees C, and ultrasonic stirring time is 20-30 minutes to obtain graphene dispersion. The graphene dispersion is mixed with water and concrete to obtain graphene concrete. USE - Method for preparing graphene concrete used to construct walls in prefabricated buildings (claimed). ADVANTAGE - The method greatly improves the strength and service life of traditional concrete.
