NOVELTY - Preparation of anti-freezing regeneration concrete comprises crushing waste concrete, filtering prefabricated coarse aggregate particles, soaking in graphene dispersion liquid, taking out, and drying to obtain regenerated coarse aggregate; and taking 270-290 pts. wt. cement, 830-850 pts. wt. regenerated coarse aggregate, 830-850 pts. wt. fine aggregate, 110-130 pts. wt. admixture, 40-50 pts. wt. waste foamed rubber powder, 170-180 pts. wt. water, 6-8 pts. wt. antifreeze water reducer and 5-10 pts. wt. expansion anti-cracking agent, and stirring. USE - The method is for preparation of anti-freezing regeneration concrete ADVANTAGE - The method enables to prepare anti-freezing regeneration concrete, which has good antifreeze thawing effect, and excellent mechanical strength, and reduces the quality loss rate of the regeneration concrete and improves the performance of the regenerated coarse aggregate, so as to improve the antifreezing performance. The method is simple and easy to operate, and does not need extra carbon black.
