Repair material for historical building brick wall cracks and construction method
The invention discloses a repairing material for historical building brick wall cracks and a construction technology. The repairing material is prepared from the following raw materials in parts by mass: 35 to 55 parts of ordinary Portland cement, 3 to 10 parts of CaO, 6 to 9 parts of fly ash, 2 to 5 parts of mineral powder, 3 to 7 parts of special emulsion for repairing ancient bricks, 0.05 to 0.15 part of wetting agent, 0.08 to 0.20 part of dispersing agent, 23 to 35 parts of water and 7 to 10 parts of color paste. Before use, the powder material and the liquid material are uniformly mixed according to the mass ratio of (2.5-3.6): 1, and the diseases of the ancient brick can be repaired and maintained by adopting construction processes such as a mud jacking method, a mud rising method, secondary plastering and the like. The prepared repairing material improves the bonding strength with the original ancient brick, has excellent compression resistance, hydrophobicity and dry shrinkage resistance, can improve the mechanical and durability of the repaired historical building brick wall, and strictly follows the repairing principle that the historical building is repaired as old as old.
本发明公开了一种用于历史建筑砖墙裂缝的修复材料及施工技术，以质量分数计所述修复材料的原料组成如下：普通硅酸盐水泥35‑55份、CaO3‑10、粉煤灰6‑9、矿粉2‑5、古砖修复专用乳液3‑7、润湿剂0.05‑0.15、分散剂0.08‑0.20、水23‑35、色浆7‑10。使用前将粉料与液料按照质量比2.5‑3.6:1混合均匀，可采用压浆法、冒浆法、二次抹灰等施工工艺对古砖的病害进行修补及维护。所制备修复材料提高了与原古砖的粘接强度，并具有优良的抗压、憎水以及抗干缩性能，可提高修复后的历史建筑砖墙的力学及耐久性能，严格遵循历史建筑修旧如旧的修复原则。
