Construction process for repairing outer wall of building
The invention discloses a construction process for building exterior wall repair, and relates to the technical field of building construction.A capillary crystalline waterproof interface agent is used in the process and comprises 1-3 parts of graphene oxide, 2-5 parts of starch, 2-3 parts of sodium citrate, 3-5 parts of modified sodium silicate I, 1-2 parts of a water reducing agent and 0.1-0.5 part of a sodium hydrogen sulfite initiator. Hydrophobic long-chain organic ammonium salt is introduced into modified sodium silicate, permeation of water can be prevented, ion migration can be slowed down, the capillary crystalline waterproof interface agent has the characteristics of increasing the compactness of concrete and improving the strength of the concrete, after the waterproof interface agent acts on a construction surface, the waterproof interface agent permeates in the concrete with water as a carrier, and the waterproof performance of the concrete is improved. Then, branch-tendril-shaped needle-shaped crystals grow in the concrete, and after moisture is volatilized, the crystals are tightly combined with the concrete to block capillary channels to prevent water from permeating, so that the waterproof and leaking stoppage purposes are achieved; by providing the cement mortar reinforcing agent, the cohesiveness of cement mortar is improved.
本发明公开了一种用于建筑物外墙修复的施工工艺，涉及建筑施工技术领域，该工艺中使用渗透结晶型防水界面剂，包括：1‑3份氧化石墨烯、2‑5份淀粉、2‑3份柠檬酸钠、3‑5份改性硅酸钠Ⅰ、1‑2份减水剂、0.1‑0.5份亚硫酸氢钠引发剂，在改性硅酸钠中引入疏水性长链有机铵盐，可以阻止水分的渗透，而且可以能减缓离子迁移，该渗透结晶型防水界面剂能增加混凝土密实度和提高混凝土强度的特性，防水界面剂与施工面作用后，防水界面剂以水为载体在混凝土中渗透，然后在混凝土内部生长成枝蔓状针型结晶体，水分挥发后，晶体与混凝土紧密结合，堵塞毛细孔道阻止水的渗透，达到防水堵漏目的；通过提供一种水泥砂浆加固剂提高水泥砂浆的粘结性。
