Self-compacting waterproof material for repairing post-cast strip and preparation method of self-compacting waterproof material
The invention provides a self-compacting waterproof material for post-cast strip repair, which is prepared from the following components in parts by weight: ordinary Portland cement, low-temperature calcined rice hull ash, graded sand, a self-repairing master batch, a polycarboxylate superplasticizer, modified coconut fiber, an organic silicon defoaming agent and low-viscosity cellulose ether, the self-repairing master batch comprises a mixture of a capillary crystalline master batch, anhydrous calcium sulfate crystals and activated aluminum oxide. The invention further provides a preparation method of the material and an in-situ grouting repair construction technology. According to the prepared self-compacting material, through matching of the materials, an excellent internal space and self-repairing performance are given to a system, the impermeability is excellent, the pouring problem of a special-shaped concrete structure with the high reinforcement ratio is effectively solved, the super-strong water retention performance is achieved, newly-stirred slurry has good cohesiveness and wrapping performance, the fluidity is excellent, segregation and bleeding are avoided, and the self-compacting material has the good water retention performance. And the method also has good homogeneity and workability.
本发明提供了一种后浇带修复用自密实防水材料，以重量份计，包括以下组分：普通硅酸盐水泥、低温煅烧稻壳灰、级配砂、自修复母料、聚羧酸减水剂、改性椰壳纤维、有机硅消泡剂、低粘纤维素醚；所述自修复母料包括渗透结晶母料、无水硫酸钙晶体、活性氧化铝的多种混合。本发明还提供了材料的制备方法和原位灌浆修复的施工技术。本发明制得的自密实材料，通过材料的适配，给予了体系优异的内部空间和自修复性能，抗渗性优异，有效解决了异形、配筋率高的混凝土结构的浇筑问题，具有超强的保水性能，新拌浆体具有良好的黏聚性和包裹性，流动性优良，不离析泌水，还具有良好的匀质性和工作性。
