Lightweight grouting material for repairing hollowing of wall thermal insulation system and preparation method
The invention belongs to the technical field of building materials, and provides a lightweight grouting material for repairing hollowing of a wall insulation system and a preparation method. The lightweight grouting material comprises a ternary cementing material, an auxiliary cementing material, latex powder, cellulose ether, a water reducing agent, an air entraining agent, an antifoaming agent,a water repellent, an expanding agent, lightweight aggregate and quartz sand, wherein the ternary cementing material is formed by mixing Portland cement, sulphoaluminate cement and gypsum, and the auxiliary cementing material is a mixture of titanium slag micro-powder and fly ash. The lightweight grouting material is simple to prepare and convenient to use, and has the advantages of easiness in grouting, good hollowing repairing effect, controllable setting time and operable time, small volume density, no segregation or layering, quicker early strength development, higher strength, high bonding strength with a matrix, no shrinkage cracking problem and the like; the grouting material is suitable for hollowing repair projects of various wall exterior and wall interior thermal insulation systems, and other grouting repair projects with low requirements on compressive strength and high requirements on adhesive properties.
本发明属于建筑材料技术领域，提供了一种墙体保温体系空鼓修补用轻质灌浆材料及制备方法，轻质灌浆材料包括三元胶凝材料、辅助胶凝材料、乳胶粉、纤维素醚、减水剂、引气剂、消泡剂、憎水剂、膨胀剂、轻骨料以及石英砂，其中，三元胶凝材料由硅酸盐水泥、硫铝酸盐水泥、石膏混合而成，辅助胶凝材料为钛渣微粉与粉煤灰的混合物。该轻质灌浆材料制备简单，使用方便，具有易灌注、空鼓修补效果好、凝结时间和可操作时间可控，体积密度小、无离析分层，早期强度发展较快，强度较高，与基体的粘结强度高，无收缩开裂问题等优点，适用于各类墙体外及墙体内保温体系的空鼓修补工程，及一些对抗压强度要求低但对粘结性能要求高的其他灌浆修补工程。
