Energy-saving type concrete crack repairing agent
The invention discloses an energy-saving type concrete crack repairing agent which comprises the following components in parts by weight: 12-18 parts of sand, 5-10 parts of a quartz powder, 20-35 parts of ordinary portland cement, 10-18 parts of sulphoaluminate cement, 6-12 parts of sodium silicate, 5-9 parts of a polyvinyl acetate emulsion powder, 3-7 parts of silica fume, 7-10 parts of a slag powder, 6-9 parts of fly ash, 8-10 parts of an expansive agent, 0.4-0.6 part of a polycarboxylic acid type high-efficiency water-reducing agent, and 0.2-0.4 part of polypropylene fiber. The concrete repairing agent has high bonding strength, and significantly improves the binding force between a new concrete interface and an old concrete interface; the concrete repairing agent is short in congealing curing time, fast in development of strength after congealing, and suitable for rapid repairing; the concrete repairing agent has the advantages of environmental protection, no toxicity, no smell, harmlessness to human bodies, single-component construction, and no pollution to the environment; and the concrete repairing agent can be used for repairing of concrete cracks, holes, honeycombs and pock marks, and drawing repairing of seams of face bricks and mosaic.
