▎ 摘  要

NOVELTY - Corrosion-resistant concrete, comprises 60-80 pts. wt. cement, 800-960 pts. wt. regenerated aggregate, 50-60 pts. wt. sugarcane waste, 100-245 pts. wt. fly ash, 20-25 pts. wt. anti-corrosion agent, and 80-110 pts. wt. water. The anti-corrosion agent comprises 8-12 pts. wt. modified graphene oxide, 6-10 pts. wt. silicon carbide and 2-4 pts. wt. butyl methacrylate. The anti-corrosion concrete is fed into waste gas from thermal power generation for mineralization maintenance. USE - Corrosion-resistant concrete. ADVANTAGE - The anti-corrosion concrete has high strength, good anti- corrosion effect, and can seal carbon dioxide in the preparation process, reduces the carbon discharge and reduces the recovery of the waste material, is environment-friendly product, and improves the early strength of the concrete and anti-chloride ion corrosion ability. The butyl methacrylate corrosion inhibitor has good viscosity and toughness, can improve the filling efficiency of concrete corrosion inhibitor, can generate self-polymerization to form high polymer, and silicon carbide and modified oxidation graphene form a three-dimensional net-shaped structure. The corrosion of the chloride ion in the concrete to the concrete is reduced. The calcium hydroxide and hydrated calcium silicate gel the mortar can absorb the carbon dioxide in the environment to form inorganic carbonate with good stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the preparation method of corrosion-resistant concrete
