Multi-component composite mortar for repairing and reinforcing concrete member and preparation method of multi-component composite mortar
The invention provides multi-component composite mortar for repairing and reinforcing a concrete member and a preparation method of the multi-component composite mortar. The multi-component composite mortar is prepared from the following components in parts by mass: 0.368 part of cement, 0.414 part of fly ash, 0.138 part of mineral powder, 0.08 part of an expanding agent, 0.02 part of rubber powder, 0.454 part of sand, 0.013 part of fiber, 0.03 part of a water reducing agent and 0.3 part of water. Accurately weighing the raw materials, and dissolving the water reducing agent in water; stirring the sand and the rubber powder to obtain a dry material 1; sequentially adding the cement, the fly ash, the mineral powder and the expanding agent into the dry material 1, and uniformly mixing to obtain a dry material 2; pouring 80-90% of water in which a water reducing agent is dissolved into the dry material 2, and adding fibers while stirring at a low speed; and adding the rest of the water reducing agent to obtain the mortar mixture. The multi-component composite repairing and reinforcing mortar has high compatibility with an existing concrete member, has excellent mechanical properties and durability, and can powerfully repair and reinforce a damaged concrete matrix. The method is suitable for repairing and reinforcing existing concrete members of historical buildings, cultural relic buildings and damaged buildings.
本申请提供了一种混凝土构件修复加固用多元复合砂浆及其制备方法，由水泥0.368份，粉煤灰0.414份，矿粉0.138份，膨胀剂0.08份，胶粉0.02份，砂子0.454份，纤维0.013份，减水剂0.03份，水0.3份质量份组成。准确称取原材料，减水剂水中溶解；砂子和胶粉搅拌获得干料1；水泥、粉煤灰、矿粉和膨胀剂依次加入干料1，混匀得干料2；80％～90％溶有减水剂的水倒入干料2，低速搅拌中加入纤维；加入余下减水剂得到砂浆拌合物。多元复合修复加固砂浆与既有混凝土构件具有高度的相容性，同时具有优异的力学性能和耐久性能，对于受损的混凝土基体起到强有力的修复与加固。适于历史建筑、文物建筑和受损建筑既有混凝土构件的修复与加固。
