Graphene oxide modified high-corrosion-resistance concrete and preparation method thereof
The invention discloses graphene oxide modified high-corrosion-resistance concrete and a preparation method thereof. Each cubic meter of the concrete comprises the following components: 150 to 220 kg of Portland cement, 20 to 40 kg of sulphoaluminate cement, 100 to 200 kg of mineral powder, 50 to 100 kg of fly ash, 20 to 50 kg of desulfurized gypsum, 10 to 20 kg of a nano modifier, 0.1 to 0.8 kg of a defoaming agent, 4 to 8 kg of a super plasticizer, 0.1 to 0.5 kg of graphene oxide, 600 to 800 kg of sand, 900 to 1200 kg of stones and 150 to 210 kg of tap water. The preparation method comprises the following steps: 1, feeding 150 to 220 kg of Portland cement, 20 to 40 kg of sulphoaluminate cement, 100 to 200 kg of mineral powder, 50 to 100 kg of fly ash, 20 to 50 kg of desulfurized gypsum, 10 to 20 kg of a nano modifier, 600 to 800 kg of sand and 900 to 1200 kg of stone in sequence; 2, diluting 0.1 kg to 0.5 kg of graphene oxide with 150 kg to 210 kg of tap water, and adding 4 kg to 8 kg of a super plasticizer; and 3, adding the mixed solution obtained in the step 2 and 0.1-0.8 kg of a defoaming agent. The concrete has the beneficial effects that the water-binder ratio is greatly reduced, and meanwhile, the defoaming agent can eliminate bubbles introduced in the concrete forming process, so that the strength and corrosion resistance of the concrete are improved.
