Description

Fiber healing agent uniform mixing device for actively repairing concrete cracks
Technical Field
The invention relates to the technical field of concrete crack repair, in particular to a uniform fiber healing agent mixing device for active repair of concrete cracks.
Background
With the deep research of concrete crack repairing technology, a self-repairing treatment mode is developed in recent years, and the representative modes are as follows: chemical self-repair (continuously trying the types of adhesives and testing the influence of the repair fibers on the strength of concrete); the calcium carbonate matrix is added with the porous woven mesh for self-repairing (the finally formed composite material is a composite material with excellent inorganic and organic combination properties similar to the animal skeleton structure); self-diagnosis and self-repair of concrete structure damage are realized by means of the sensor.
The self-repairing mode adopted in the prior art is as follows: the first mode is that water glass, diluted water glass and epoxy resin are used as repairing agent separately and injected into hollow microcapsule, and the hollow microcapsule containing repairing agent is mixed into concrete material to crack the concrete member under the action of external force to break partial microcapsule and the repairing agent flows out to heal the crack of concrete. The second mode is that the surface is coated with a wax layer, and polypropylene fiber injected with adhesive is pre-embedded in concrete; when the concrete matrix cracks, heating the concrete matrix to melt paraffin on the surface of the fiber tube, and enabling the adhesive to flow into the cracks from the pores in the wall of the fiber tube; and (4) continuing heating, and curing the adhesive and filling cracks along with the increase of the temperature. Research results show that the compressive strength and the impermeability of the repaired concrete are improved. Because a large number of micro gaps exist in the concrete matrix and provide natural storage places for the microcapsules, the microcapsules with self-repairing capability become one of the repairing modes widely used in the building field; however, when concrete is poured, the concrete has certain fluidity, and microcapsules with smaller sizes are easy to agglomerate, so that the distribution of the microcapsules in a formed concrete matrix is in an uneven state, when concrete cracks appear, the microcapsules with smaller or zero quantity exist in the area, the only way for solving the defects is to increase the putting amount of the microcapsules, and the treatment means tends to greatly increase the construction cost of a foundation.
