Ultrahigh-strength repairing mortar for building
The invention relates to the technical field of building materials, and discloses an ultrahigh-strength repair mortar for buildings, which is prepared from the following raw materials in parts by weight: 260 to 480 parts of cement, 260 to 600 parts of quartz sand, 50 to 150 parts of superfine slag powder, 10 to 16 parts of redispersible latex powder, 0.5 to 2 parts of high-efficiency water reducing agent, 1 to 3 parts of water-retaining agent and 1 to 3 parts of 602 thixotropic agent. According to the ultrahigh-strength repairing mortar for the building, through the cement, the quartz sand, the superfine slag powder, the redispersible latex powder, the high-efficiency water reducing agent, the water-retaining agent and the 602 thixotropic agent, the water-retaining property is larger than or equal to 90%, the construction performance is good, the bonding force with a base layer is larger than or equal to 2.5 MPa, hollowing and cracking are avoided, and the 28-day compressive strength is larger than or equal to 75 MPa. The problems that similar products are poor in water-retaining property, inconvenient to maintain, poor in binding power with base concrete, poor in construction performance and low in mechanical property are solved.
本发明涉及建筑材料技术领域，且公开了一种建筑用超高强修补砂浆，包括以下重量份数配比的原料：水泥260～480份，石英砂260～600份，矿渣微粉50～150份，可再分散乳胶粉10～16份，高效减水剂0.5～2份，保水剂1～3份，602触变剂1～3份。该建筑用超高强修补砂浆，通过水泥、石英砂、矿渣微粉、可再分散乳胶粉、高效减水剂、保水剂、602触变剂，保水性≥90％，施工性能好，与基层粘结力≥2.5MPa，不空鼓不开裂，28天抗压强度≥75MPa，本修补材料抗折强度要求高同时又有修补时间要求的工程，解决了同类产品保水性差、养护不方便、与基层混凝土粘结力差、施工性能欠佳力学性能低的问题。
