NOVELTY - The preparation method of antifreeze concrete, involves (1) mixing water and ethanol to obtain mixed solution (M1), (2) dispersing graphene in the mixed solution (M1), mixing hexamethylene diisocyanate and N-methylpyrrolidone to obtain mixed solution (M2), (3) mixing water, ethylene glycol, urea, calcium formate, mixed solution (M2) and nano calcium carbonate and drying to obtain concrete antifreezing agent, and (4) mixing water, cement, sand, fly ash, water reducing agent and concrete antifreezing agent. USE - Preparation of antifreeze concrete. ADVANTAGE - The method enables preparation of concrete with enhanced antifreezing performance.
