Composite coagulation-accelerating anticorrosive material and preparation method thereof
The invention discloses a composite coagulation-accelerating anticorrosive material and a preparation method thereof. The composite coagulation-accelerating anticorrosive material comprises the following raw materials in parts by mass: 45-55 parts of a mineral admixture, 16-25 parts of an anticorrosive component, 8-12 parts of a reinforcing agent, 10-15 parts of a coagulation-accelerating component and 4-8 parts of an expanding agent, the sulfate corrosion resistance of the sprayed concrete can be improved, the corrosion behavior of chloride ions on spraying layer steel bars is inhibited, the durability of the sprayed concrete is enhanced, and the service cycle of a tunnel structure is prolonged; meanwhile, the early process of cement hydration is accelerated, the synergistic complementary effect of the anticorrosive material and the accelerator in the sprayed concrete is stimulated, the actual mixing amount of the liquid alkali-free accelerator is reduced, and the construction effect of the sprayed concrete is improved.
本发明公开了一种复合促凝型防腐材料及制备方法，所述复合促凝型防腐材料包括以下质量份原料：矿物掺合料45～55份，防腐组分16～25份，增强剂8～12份，促凝组分10～15份，膨胀剂4～8份；其能够提升喷射混凝土的抗硫酸盐侵蚀性，抑制氯离子对喷射层钢筋的锈蚀行为，增强喷射混凝土的耐久性，延长隧道结构的服役周期；同时加速水泥水化早期进程，激发防腐材料与速凝剂在喷射混凝土中的协同互补作用，降低液体无碱速凝剂的实际掺量，改善喷射混凝土的施工效果。
