Impermeable setting accelerator for mountainous area tunnel and preparation method of impervious setting accelerator
The invention provides an impervious accelerator for a mountain tunnel and a preparation method thereof, and relates to the field of concrete construction. According to the anti-seepage accelerator for the mountainous area tunnel and the preparation method of the anti-seepage accelerator, raw materials comprise a coagulant, a water reducing agent, an anti-seepage agent, a suspension agent and water, the coagulant accounts for 80%-85% of the total mass of a composition, the anti-seepage agent accounts for 7%-8% of the total mass of the composition, the water reducing agent accounts for 2%-3% of the total mass of the composition, the balance is water, and the anti-seepage agent is a polyurethane anti-seepage agent. The coagulant is formed by calcining a mixture of bauxite and limestone, and the water reducing agent is a melamine water reducing agent. According to the impermeable accelerator for the mountainous area tunnel, when the liquid prepared by mixing the accelerator, the water reducing agent, the impermeable agent and the suspending agent is doped into concrete for use, sprayed concrete meeting the tunnel construction standard can be formed, and the problem that the sprayed concrete is prone to water seepage in the prior art is solved.
本发明提供一种山区隧道用抗渗型速凝剂及其制备方法，涉及混凝土施工领域。该山区隧道用抗渗型速凝剂及其制备方法，所述原料包括促凝剂、减水剂、抗渗剂、悬浊剂和水，所述促凝剂占组合物总质量的80％‑85％，抗渗剂占组合物总质量的7％‑8％，减水剂占组合物总质量的2％‑3％，其余为水，所述抗渗剂为聚氨酯类抗渗剂，促凝剂为铝矾土和石灰石混合物煅烧而成，减水剂为三聚氰胺系减水剂。该山区隧道用抗渗型速凝剂，通过促凝剂、减水剂、抗渗剂、悬浊剂混合制成的液体，在掺入到混凝土中使用时，能够形成满足隧道施工标准的喷射混凝土，解决了现有技术中喷射混凝土容易渗水的问题。
