High-strength shrinkage-free lining wall post-grouting material for seabed mining method tunnel
The invention discloses a high-strength shrinkage-free lining wall post-grouting material for a submarine mining method tunnel. The high-strength shrinkage-free lining wall post-grouting material comprises the following raw materials: cement, slag powder, lime, an alkali-activated material, sand, a high-efficiency water reducing agent, a defoaming agent, an expanding agent, a plastic expanding agent, cellulose and a capillary crystalline waterproof material. According to the invention, cement is replaced by slag powder with a large mixing amount, and the use amount of the cement is reduced through alkali excitation, so that not only is the strength of the grouting material ensured, but also the durability of the grouting material is enhanced, the environmental pollution is reduced, the cost is low, and the mortar has excellent sulfate corrosion resistance and corrosion resistance grade K150, and can better adapt to the subsea tunnel environment; after the capillary crystalline waterproof material and free alkali in the concrete are subjected to condensation reaction, branch-tendril-shaped fine particle crystals are formed, capillary pores and fine cracks of the concrete are sealed, an internal screen waterproof protection layer is formed, the compactness of the concrete is enhanced, and a plastic expanding agent is adopted to expand before slurry hardening, so that gaps are effectively filled.
本发明公开一种用于海底矿山法隧道的高强无收缩衬砌壁后注浆料，原料包括水泥、矿渣粉、石灰、碱激发材料、砂、高效减水剂、消泡剂、膨胀剂、塑性膨胀剂、纤维素、渗透结晶型防水材料；使用大掺量的矿渣粉替代水泥并通过碱激发，减少水泥用量，不仅保证注浆料强度，而且增强注浆料的耐久性能，减少环境污染，且成本较低，也使砂浆具备优异的抗硫酸盐侵蚀性能，抗蚀等级K150，更好地适应在海底隧道环境；采用渗透结晶防水材料和混凝土内的游离碱发生缩合反应后，形成枝蔓状的微细颗粒晶体，封闭混凝土的毛细孔和微细裂缝，形成一道内在屏幕防水保护层，增强混凝土密实度，采用塑性膨胀剂在浆液硬化前膨胀，有效填充空隙。
