Fair-faced concrete surface defect repairing material and preparation method thereof
The invention discloses a bare concrete surface defect repairing material. The repairing material is prepared from the following components: Portland cement, limestone powder, mineral powder, silica fume, redispersible latex powder, a water reducing agent, cellulose ether, an expanding agent, black toner and a defoaming agent, wherein the viscosity of the cellulose ether is hydroxypropyl methyl cellulose ether; and the defoaming agent is an organic silicon defoaming agent. By adjusting the ratio of the cementing material and doping the black toner, the repairing material has no chromatic aberration with the bare concrete, the powder with small particle size is adopted, the repairing material is suitable for small cracks, the problems that chromatic aberration exists and the small cracks are not easy to repair when the bare concrete is repaired are solved, the repaired cracks do not shrink due to the added expanding agent, and the repairing effect is good. The appearance quality problems of cracks, voids, pitted surfaces, mottles or coarse aggregate transparent layers and the like of the fair-faced concrete can be effectively solved, the repairing material has the properties of good bonding strength, high wear resistance and the like, and no color difference with the fair-faced concrete is achieved.
本发明公开了一种清水混凝土表面缺陷修复材料，修复材料由以下组分制成：硅酸盐水泥，石灰石粉，矿粉，硅灰，可再分散乳胶粉，减水剂，纤维素醚，膨胀剂，黑色色粉，消泡剂，纤维素醚为粘度为羟丙基甲基纤维素醚；消泡剂为有机硅消泡剂。本发明通过调整胶凝材料的配比并且掺入黑色色粉使得修复材料与清水混凝土无色差，采用粒径较小的粉剂，适合细小裂缝，解决清水混凝土修补时具有色差和细小裂缝不易修补的问题，加入的膨胀剂使修补后的裂缝不会收缩，能有效的解决清水混凝土出现的裂缝、蜂窝麻面、花斑或粗骨料透明层等外观质量的问题，实现修复材料具有较好粘结强度和高耐磨等性能，达到与清水混凝土无色差。
