Magnesium cement concrete, application and underground building anticorrosion method
The invention provides magnesium cement concrete, application thereof and an underground building anti-corrosion method, and relates to the technical field of building materials. The magnesium cement concrete provided by the invention comprises active magnesium powder, a magnesium salt solution, sand, gravel and a modifier, the mass ratio of the active magnesium powder to the magnesium salt solution to the sand to the gravel to the modifier is 1: (0.5-1.5): (1-3): (2-6): (0.1-0.3); the modifier comprises fly ash and phosphoric acid, or fly ash, ferric sulfate and nano-zinc oxide; the mass fraction of the magnesium salt solution is 20-40%. The corrosion resistance of the magnesium cement concrete after curing is improved through the inherent salt-tolerant property of the magnesium cement concrete. In addition, magnesium cement concrete is used as an underground building anticorrosive material, and magnesium cement concrete is used as an outermost anticorrosive coating of the underground building, so that brine scouring can be prevented, and the service life of the underground building is prolonged.
本发明提供了一种镁水泥混凝土及其应用、地下建筑物防腐方法，涉及建筑材料技术领域。本发明提供的镁水泥混凝土包括活性镁粉、镁盐溶液、砂子、碎石和改性剂；所述活性镁粉、镁盐溶液、砂子、碎石和改性剂的质量比为1：0.5～1.5：1～3：2～6：0.1～0.3；所述改性剂包括粉煤灰和磷酸，或者粉煤灰、硫酸铁和纳米氧化锌；所述镁盐溶液的质量分数为20～40％。本发明通过镁水泥混凝土自身固有的耐盐属性，提高固化后镁水泥混凝土的耐腐蚀性能。此外，通过镁水泥混凝土作为地下建筑物防腐材料，配合镁水泥混凝土作为地下建筑物最外层的防腐涂层，能够防止卤水的冲刷，延长地下建筑物使用寿命。
