Description
Technical Field
The invention relates to the technical field of concrete crack repair, in particular to a fiber healing agent uniform mixing device for active concrete crack repair.
Background
With the deep research of concrete crack repairing technology, a self-repairing treatment mode is developed in recent years, and the method is represented as follows: chemical self-repairing (continuous attempts are made to the type of adhesive, and the influence of repairing fibers on the strength of concrete is tested); adding a calcium carbonate matrix into a porous woven mesh for self-repairing (finally forming a composite material which has excellent inorganic-organic phase combination property similar to that of an animal bone structure); and the sensor is used for realizing the self-diagnosis and self-repair of the damage of the concrete structure.
The self-repairing formula adopted in the prior art is as follows: the first mode is to use water glass, diluted water glass and epoxy resin as repairing agent, to inject the repairing agent into the hollow microcapsule, then to mix the hollow microcapsule containing repairing agent into the concrete material, the concrete member is cracked under the action of external force to cause partial microcapsule to crack, and the repairing agent flows out to heal the concrete crack. The second mode is to pre-embed the polypropylene fiber with the outer surface coated with a wax layer and the inner surface injected with adhesive in the concrete; when the concrete matrix is cracked, heating the concrete matrix to melt paraffin on the surface of the fiber pipe, and allowing the adhesive to flow into the crack from the pore in the fiber pipe wall; continuing to heat, as the temperature increases, the adhesive solidifies, filling the crack. The research result shows that the compressive strength and the impermeability of the concrete after the repair are improved. The microcapsule with self-repairing capability becomes one of repairing modes widely used in the building field because a large number of micro-gaps exist in the concrete matrix and provide natural storage places for the microcapsule; however, when concrete is poured, the concrete has certain fluidity, and the microcapsules with smaller size are easy to agglomerate, so that the distribution of the microcapsules in a formed concrete matrix is in an uneven state, and when concrete cracks appear, the microcapsules with smaller number or zero number exist in the areas, and the only way to solve the defects is to increase the throwing amount of the microcapsules, so that the treatment means tend to greatly increase the construction cost.
