Alkali-activated repairing material for repairing concrete cracks and preparation method of alkali-activated repairing material
The invention provides an alkali-activated repairing material for repairing concrete cracks. The alkali-activated repairing material comprises the following components in parts by weight: 0.8-1 part of sodium carbonate water glass, 0.08-0.1 part of sodium hydroxide, 2.5-4 parts of water, 2-3 parts of grey cement, 3-4 parts of white cement, 0.5-1 part of redispersible latex powder and 0.2-0.3 part of cellulose. Compared with the prior art, the alkali-activated repairing material for repairing the concrete crack is used for repairing the crack of a precast concrete member, and has the characteristics of simple formula, easily available raw materials, short strength increasing time, slight expansion, high construction speed, capability of meeting the requirement of large-batch repairing, low price and the like. The repairing material has very high cost performance and can also achieve color-difference-free repairing, and after repairing and polishing are completed, the color of a repaired part is basically consistent with that of an unrepaired part.
本发明提供一种用于混凝土裂缝修补的碱激发修补料，包括按重量计的以下组分：碳酸钠水玻璃0.8~1份、氢氧化钠0.08~0.1份、水2.5~4份、灰水泥2~3份、白水泥3~4份、可再分散性乳胶粉0.5~1份，纤维素0.2~0.3份。与现有技术相比，本发明混凝土裂缝修补的碱激发修补料，用于预制混凝土构件裂缝的修补，此种修补料具有配方简单、原料易得、上强度时间短、有微膨胀的特点以及施工速度快，可满足大批量修补的需求、价格便宜等优点。具有非常高的性价比，并且它还能做到无色差修补，修补完成并打磨之后，修补部位颜色跟未修补部位颜色基本一致。
