Corrosion-resistant concrete for offshore sewage pipeline and preparation method of corrosion-resistant concrete
The invention provides corrosion-resistant concrete for an offshore sewage pipeline and a preparation method of the corrosion-resistant concrete. The concrete comprises the following components: 150-200 parts of ordinary Portland cement, 180-220 parts of mineral powder, 50-70 parts of fly ash, 15-30 parts of silica fume, 12-20 parts of desulfurized gypsum, 5-9 parts of a polycarboxylic acid high-performance water reducing agent, 12-20 parts of an expanding agent, 2-6 parts of basalt fibers, 0.05-0.8 part of modified multi-walled carbon nanotubes, 600-800 parts of sand, 950-1100 parts of stonesand 160-175 parts of water. The prepared corrosion-resistant concrete for the offshore sewage pipeline has good mechanical properties and corrosion resistance, the quality of the offshore sewage pipeline is improved, and the service life of the offshore sewage pipeline is prolonged.
