Polymer plugging grouting material, preparation method and construction method
The invention discloses a polymer plugging grouting material, a preparation method and a construction method, and belongs to the field of building materials. The material comprises 35-45% of Portland cement, 30-40% of quick-hardening sulphoaluminate cement, 10-20% of quartz sand, 0.5-2% of re-decomposed latex powder, 1-5% of capillary crystalline master batch, 0.5-5% of a micro-expanding agent, 0.1-1% of a defoaming agent and 0.5-2% of a high-efficiency water reducing agent. The polymer plugging grouting material disclosed by the invention is small in shrinkage after being cured and high in bonding performance with concrete. The material is applicable to plugging of cement bases and sand bases, is also applicable to plugging of concrete, has the effects of reverse osmosis crystallization repair, compaction and reinforcement on concrete structure cracks, sand holes and other diseases, and ishigh in tensile strength, durability and stability. The raw materials are rich in source, the usage amount is small, environmental pollution is small, operation is safe and convenient, pressure injection equipment is simple, and grouting investment is greatly saved.
本发明公开了一种高分子堵漏灌浆料及制备方法和施工方法，属于建筑材料领域。包括硅酸盐水泥35‑45％，快硬硫铝酸盐水泥30‑40％、石英砂10‑20％,再分解乳胶粉0.5‑2％、渗透结晶母料1‑5％、微膨胀剂0.5‑5％、消泡剂0.1‑1％、高效减水剂0.5‑2％。本发明高分子堵漏灌浆料固化后收缩小，与混凝土粘结性能好。不仅能够适用于水泥基、砂基的堵漏，还适用于混凝土的堵漏，对混凝土结构裂缝、砂眼等病害具有反渗透结晶修复、密实补强功效，抗拉强度，耐久性、稳定性好。原料来源丰富，且使用量少，对环境污染少，操作安全、方便，压注设备简单，大大节省了注浆投资。
