Tunnel lining corrosion-resistant concrete suitable for carbonate strong corrosion environment, preparation method and tunnel lining
The invention relates to the technical field of tunnel lining materials, and discloses tunnel lining corrosion-resistant concrete suitable for a carbonate strong corrosion environment, a preparation method and a tunnel lining. The invention relates to tunnel lining corrosion-resistant concrete applicable to a carbonate strong corrosion environment. The tunnel lining corrosion-resistant concrete is prepared from the following raw materials in parts by mass: 1 part of cement, 1.37 to 2.29 parts of fine aggregate, 1.82 to 3.04 parts of coarse aggregate, 0.35 to 0.40 part of water, 0.10 to 0.20 part of mineral powder, 0.05 to 0.062 part of silica fume, 0.015 to 0.021 part of diatomite, 0.015 to 0.0154 part of Ba (OH) 2, 0.005 to 0.015 part of BaCO3, 0.005 to 0.015 part of sorbitol and 0.01 to 0.012 part of a water reducing agent. The coating has the effects of high strength, high durability, high constructability and low rubber material content.
