NOVELTY - Modified graphene-reinforced anti-freeze concrete comprises 8-12 wt.% modified graphene composition intercalated oil shale. USE - Used as modified graphene-reinforced anti-freeze concrete. ADVANTAGE - The concrete has excellent frost resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing modified graphene reinforced antifreeze concrete comprising preparing modified graphene by uniformly dispersing graphene in deionized water to prepare a graphene dispersion, adding 0.1% sodium hypochlorite to the dispersion, heating to 65 degrees C, stirring at 120 revolutions/minute (rpm) for 40 minutes, adding 0.05-0.07% potassium trimethyl silanolate, stirring at 500 rpm for 2 hours, keeping for 1 hour, filtering, washing and drying to a constant weight, and (ii) preparing modified graphene composition intercalated oil shale by crushing oil shale, sieving through a 300 mesh sieve to obtain oil shale powder, uniformly dispersing the powder into an organic solvent, adding silane sodium hydroxide and deionized water, heating to 66 degrees C, stirring for 2.5-3 hours, cooling to room temperature, continuously stirring for 5 hours, adding triethylamine and modified graphene, adjusting the temperature to 50 degrees C, stirring for 40 minutes, naturally cooling to room temperature, removing the solvent by rotary evaporation, washing with absolute ethanol and deionized water for 10 minutes, and drying to a constant weight.
