NOVELTY - Method for preparing high early strength graphene cement slurry, involves (a) using an ultrasonic cell crusher to ultrasonically disperse the graphene dispersion liquid in the ice water bath environment, (b) adding the graphene dispersant liquid into the cement to stir, then pouring into the mold, using preservative film sealing mold to prevent water loss, (c) allowing to stand for 2 hours to 4 hours at 20-21degrees Celsius, removing preservative membrane, placing the mold in the electric heating constant temperature water bath at 55-60degrees Celsius for 6-22 hours, taking out the mold from the water bath, naturally cooling to 20-21degrees Celsius and dismounting the mold to obtain the cementing slurry. USE - Method for efficiently preparing high early strength oxidized graphene cement slurry used for building construction, bridge, dam, road and other facilities. Can also be used in high speed railway and rail traffic. ADVANTAGE - The method enables to prepare high early strength oxidized graphene cement slurry that improves the early mechanical property of the cement-based material, and reduces the total porosity of the composite material, improves the curing temperature and adding graphene oxide, the two synergistic to further exert effect.
