Description
[technical field]
The present invention relates to concrete reinforcement, particularly relate to inorganic glue fibrous composite reinforcement and the side of protecting concrete by
Method.
[background technology]
Xoncrete structure under arms during owing to jointly being acted on various environmental corrosion media by load, and gradually send out
Raw structure deterioration, causes crackle occur, and crack is even destroyed, thus reduced the safety of concrete structure, shortens and uses the longevity
Life.In order to repair the xoncrete structure of deterioration in time, it is ensured that its safety used, extend its service life, it is necessary to deterioration
Concrete carry out repairing and reinforcement.At present, reinforcement and strengthening many employings surface mount fibre reinforced composites of concrete, example
The fibre reinforced composites (CFRP) constituted with epoxy organic gel such as carbon cloth.CFRP has high-strength, efficient, light weight and executes
The convenient advantage of work and be used widely, define the technical system of comparative maturity, China has also formulated that " xoncrete structure adds
Gu design specification " (GB50367-2006) and " structure reinforcement and repair carbon fiber plate " (GB/T21490-2008).But paste
Epoxies organic gel have following defect, (1) softening temperature is relatively low, mostly typically is 60～80 DEG C, meeting under high temperature and fire
Volatilizing toxic gas, therefore epoxy radicals can be typically considered poisonous or carcinogen with the multiple radical reaction in human body
Matter, this brings threat greatly to the security of the lives and property of people；(2) meeting accelerated ageing, serious shadow under ultraviolet irradiation
Ring adhesive property；(3) big with the elastic modelling quantity gap of the concrete material of mineral-type, repeatedly expanding with heat and contract with cold and moisture expansion and drying shrinkage follows
Under the conditions of ring, both deformations, it is easily generated crack, thus poor compatibility.For such issues that, application for a patent for invention
(CN102351443A, CN201210356357), discloses high temperature resistant alkali slag gel material and preparation method thereof, can be necessarily
The problem solving epoxies organic gel non-refractory in degree, but because its construction method is comparatively laborious, be unfavorable in engineering reality
Popularization and application.
[summary of the invention]
The inorganic glue that the technical problem to be solved in the present invention is to provide a kind of safe and environment-friendly, life-span length and easy construction is fine
Tie up composite reinforcement and protect concrete by method.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is, a kind of inorganic glue fibrous composite is mended
Strong and protect concrete by method, paste inorganic adhesive-fibre sheet material layers of reinforcement, construction bag at surface of concrete structure
Include following steps:
(1) surface of concrete component is carried out coarse process；
(2) mixed with water by inorganic coagulation material, stir formation inorganic adhesive；
(3) at the one layer of inorganic adhesive of surface uniform application of the concrete component handled well；
(4) on the inorganic adhesive that fibre sheet material is pasted onto；
(5) fibre sheet material paved, be compacted, after aerofluxus again at one layer of inorganic adhesive of fibre sheet material outer surface brushing；
(6) if using the inorganic adhesive-fibre sheet material layers of reinforcement of multi-layer fiber sheet material, then step (4) is repeated
(5).
The process described above, described fibre sheet material is unidirectional fiber layers or fiber fabric layer.
The process described above, described fiber is in glass fibre, carbon fiber, basalt fibre or aramid fiber
Kind or multiple combination.
Above method, described inorganic adhesive is phosphate adhesive, phosphate adhesive by weight, by following group
It is grouped into:
The process described above, phosphate adhesive is by weight, composed of the following components:
The process described above, the described 8%-15% that retarder weight is magnesia weight；The weight of water is phosphate glue
The 18-25% of gel material percentage by weight.
The process described above, described dihydric phosphate is in potassium dihydrogen phosphate, sodium dihydrogen phosphate and ammonium dihydrogen phosphate
At least one, described inorganic mineral filler is flyash, wollastonite in powder, ground granulated blast furnace slag, steel-making slag powder, Kaolin, higher
At least one in ridge soil, zeolite, described retarder is at least one in Borax and boric acid；Magnesia is reheating magnesia, electricity
At least one in fused magnesia and seawater magnesia, the magnesia content in reheating magnesia, fused magnesite or seawater magnesia is not less than
80%.
The process described above, before step (4), soaks fibre sheet material in putting inorganic adhesive and pestle smashes 3～6
Minute.
The process described above, repeats step (4) and (5), it is thus achieved that the inorganic adhesive-fibre sheet material of multi-layer fiber sheet material
Layers of reinforcement.
The method of the present invention improves rupture strength and the impact flexibility of concrete component, inorganic adhesive-fibre sheet material
Layers of reinforcement has intercepted the infiltration to concrete of the extraneous corrosive medium, and the internal material of concrete component is played reinforcement and guarantor
Protect effect, the service life of concrete can be extended.Inorganic coagulation material is close with the elastic modelling quantity of concrete material, deformation
Harmony is good, has a preferable interface compatibility, and resistance to elevated temperatures is good, life-span length, safe and environment-friendly.Concrete of the present invention
Fibrous composite reinforced structure easy construction, it is simple to popularization and application in engineering construction and reinforcing, has good economic effect
Benefit.
