High-bonding-strength flexible polymer modified mortar for repairing and reinforcing hydraulic structures and preparation method of high-bonding-strength flexible polymer modified mortar
The invention discloses high-bonding-strength flexible polymer modified mortar for repairing and reinforcing hydraulic structures and a preparation method of the high-bonding-strength flexible polymer modified mortar. The flexible polymer modified mortar with high bonding strength is prepared from the following components in parts by weight: 35 to 55 parts of cement, 1.5 to 3.5 parts of expanding agent, 0.08 to 0.12 part of fiber, 0.01 to 0.03 part of water reducing agent, 2.2 to 3.0 parts of polymer rubber powder, 0.05 to 0.15 part of bentonite, 0.01 to 0.03 part of cellulose ether, 0.01 to 0.03 part of starch ether, 6 to 9 parts of mineral admixture, 30 to 50 parts of quartz sand and 0.05 to 0.07 part of defoaming agent. The high-bonding-strength flexible polymer modified mortar disclosed by the invention has the characteristics of high bonding strength, high flexibility, small dry shrinkage rate, good durability, high bonding strength between the mortar and old concrete and the like, and various performance indexes meet the industrial compulsory standard JTS 311-2011 Technical Specification for Repair and Reinforcement of Port Hydraulic Structures. The method can be widely applied to maintenance and reinforcement engineering of hydraulic structures.
本发明公开了一种水工建筑物修补加固用高粘接强度柔性聚合物改性砂浆及其制备方法。该高粘接强度柔性聚合物改性砂浆包括以下重量份的各组分：水泥35‑55份，膨胀剂1.5‑3.5份，纤维0.08‑0.12份，减水剂0.01‑0.03份，聚合物胶粉2.2‑3.0份，膨润土0.05‑0.15份，纤维素醚0.01‑0.03份，淀粉醚0.01‑0.03份，矿物掺合料6‑9份，石英砂30‑50份，消泡剂0.05‑0.07份。本发明的高粘接强度柔性聚合物改性砂浆具有高粘接强度和高柔韧性，兼具干缩率小、良好的耐久性、砂浆与老混凝土粘接强度大等特点，各项性能指标满足行业强制性标准JTS 311‑2011《港口水工建筑物修补加固技术规范》，可广泛应用于水工建筑物的维修加固工程。
