Concrete crack repairing method and process in road and bridge construction
The invention discloses a concrete crack repairing method and process in road and bridge construction. A concrete crack repairing material for road and bridge construction is prepared from the following raw materials in parts by mass: 30-60 parts of aluminum sulfate cement, 15-25 parts of high-alumina cement, 5-10 parts of alunite, 5-12 parts of limestone, 8-15 parts of slag, 10-15 parts of fine sand, 1-3 parts of a water reducing agent, 3-8 parts of desulfurized gypsum, 3-8 parts of unsaturated polyester resin, 2-4 parts of a retarder and 1-3 parts of hydroxypropyl methyl cellulose. The invention has the beneficial effects that the new and old concrete is strong in binding property, high in compression strength and breaking strength, resistant to high temperature and corrosion, capable ofmaintaining higher adhesive strength and short in repair time, the service life of the pavement is prolonged, the automobile exhaust can be adsorbed, and the pollution is reduced.
本发明公开了一种道路桥梁施工中混凝土裂缝修补方法及其工艺，该道路桥梁施工中混凝土裂缝修补材料是由以下质量份数的原料制成：硫酸铝水泥30‑60份、高铝水泥15‑25份、明矾石5‑10份、石灰石5‑12份、矿渣8‑15份、细砂10‑15份、减水剂1‑3份、脱硫石膏3‑8份、不饱和聚酯树脂3‑8份、缓凝剂2‑4份、羟丙基甲基纤维素1‑3份。有益效果：新旧混凝土结合性强，抗压、抗折强度高，耐高温，耐腐蚀，能够维持较高的粘粘强度，修补时间短，提高了路面的使用寿命，并且能够对汽车尾气进行吸附，降低污染。
