Description
Technical field
The invention belongs to technical field of concrete, relate to a kind of Concrete crack repair material, be specifically related to a kind of super self-healing
Yardstick cracked concrete Thief zone crystallization repair materials and preparation method thereof.
Background technology
Concrete belongs to fragile material, is easier brittle cracking, in it condenses hardening process, will become due to temperature
Changing or the reason such as drying shrinkage produces small crackle, when the later stage comes into operation, the small crackle of part in certain circumstances can
Heal voluntarily, but the lower extension of the effect of major part fine crack environment around becomes bigger crackle, exceedes spontaneous recovery
Closing the yardstick threshold value of probability, this kind of crack is referred to as super self-healing yardstick.The crack of super self-healing yardstick can be to concrete
Overall performance produces and destroys, and ultimately results in concrete works and cannot normally use.This is generally to exist in concrete works
Problem, is also the main cause affecting concrete durability.The deterioration damage that concrete structure crack causes is brought
Economic loss can carry out the description of image with " five times of laws ", i.e. in structured design process, often saves l for reinforcing bar protection beautiful
Unit, that means that: occur adopting remedial measures additional maintenance cost 5 dollars when steel bar corrosion damages；Concrete surface occurs
Adopt remedial measures additional maintenance cost 25 dollars when ftractureing along muscle；Adopt remedial measures during xoncrete structure heavy damage and will chase after
Add maintenance cost 125 dollars.By " five times of laws " it can be seen that cracking concrete is the most early carried out repair process, its maintenance
Expense is the lowest, therefore carries out intervening in time for concrete bracing, retrains its cracking yardstick, it is achieved repair target.
At present, the repair materials for distress in concrete is broadly divided into three kinds, is inorganic repair materials, organic reparation respectively
Material and Organic-inorganic composite repair materials.Inorganic repair materials is primarily referred to as cement based repair materials, and its range of application is the most
Extensively, technology also corresponding comparative maturity, but in application process, adhesive property is bad；Organic repair materials is to have certain
The Organic substance of reparation characteristic, as repairing host, is aided with the organic substances such as toughener, initiator and coupling agent and admixes together,
Making it have the effect repairing distress in concrete, compared with inorganic repair materials, it has a characteristic that adhesion strength is high, but greatly
Partial organic substances belongs to noxious substance, in use should avoid the injury to the person as far as possible；With inorganic material as matrix, auxiliary
With the Organic-inorganic composite repair materials of organic substance composition, the adhesive property of inorganic repair materials can be improved, the most organic
The good flexibility that material is had can give repair materials preferable mobility.
The Concrete crack repair material being had on market mostly completes crack by the hardening of repair materials self
Fill up reparation, it does not carry out the biggest improvement to concrete substrate, therefore, can enter one by admixture in repair materials
Step increases the material of matrix strength, can enter Binder Materials unhydrated in concrete while repair materials hardens
One step excites, and enables original concrete and repair materials preferably to combine together, just seems necessary.
Summary of the invention
It is an object of the invention to provide a kind of super self-healing yardstick cracked concrete Thief zone crystallization repair materials and preparation thereof
Method.
For achieving the above object, the present invention is by the following technical solutions:

Obtain super self-healing yardstick cracked concrete Thief zone crystallization repair materials.
The using method of super self-healing yardstick cracked concrete Thief zone crystallization repair materials is directly smeared from oozing for using
Repair materials is filled in crack by the mode of formula or employing low pressure pressing-in grouting formula thoroughly.
The repair materials of the present invention is repaired mainly for the crack exceeding autogenous healing conjunction yardstick threshold value, catches this
Critical state carries out upper flow regime repair materials infiltration.On the one hand crack is stoped by repair materials self aquation and high viscosity substance
Continuing cracking, on the other hand in repair materials, activating substance excites cracking position to have lateral reactivity material (unhydrated cement
Grain, mineral admixture etc.) activity, newborn product and fiber reduce fracture scale by modes such as blocking and segmentations so that it is control
System is within self-healing yardstick threshold value so that it is regain self-healing capability.
The method have the advantages that
(1) the anti-folding of repair materials of the present invention, comprcssive strength height, mobile performance is good, and setting time is moderate, the anti-folding of 28d, resistance to compression
Intensity can reach 11.5MPa and 50MPa, initial flow degree and 30min fluidity respectively all can meet strength cement-based grouting material
Technical property requirements, presetting period ＞ 45min, suitably constructs.
(2) osmotic effect is good.Concrete itself belongs to porous material, in the presence of water, and repair materials energy of the present invention
Enough penetrate in small distress in concrete, distress in concrete is repaired.
(3) adhesion strength is high.Bonding after concrete substrate water is sufficiently humidified so as to, between repair materials and concrete substrate
Intensity can reach more than 3MPa.
(4) effect of prestressed is good.Repair materials of the present invention adds water and can produce small expansion after mixing thoroughly, it is possible to better ensure that
With contacting of concrete substrate, it is possible to prevent to produce further cracking because of external load；Meanwhile, added with appropriate in this product
Polypropylene fibre, it is possible to stop repair materials to crack during harden(ing)by itself.
(5) active ion (SO4 2-、SiO4 4-、AlO3 3-Deng) penetrate into distress in concrete after, it is possible to the Ca in matrix2+
Crystallization generates precipitation, promotes the secondary hydration of unhydrated cement；Meanwhile, activity excitation ion (SO4 2-、OH-Deng) can be to gelling
In material, the activity of fly ash grain excites, and on the one hand promotes the cohesive force of repair materials and matrix, on the other hand also carries
Height self and the intensity of matrix.
(6) this product processes is simple, meets environmental protection simultaneously, and range of application is relatively broad.
