Description
[technical field]
The present invention relates to concrete reinforcement, relate in particular to the reinforcement of inorganic glue fibrous composite and the concrete method of protection.
[background technology]
Xoncrete structure under arms in process owing to being subject to load and the acting in conjunction of various environmental corrosion medium, and recurring structure is deteriorated gradually, causes occurring crackle, crack, even destroys, thereby reduces the security of concrete structure, reduction of service life.In order to repair in time deteriorated xoncrete structure, guarantee the security of its use, extend its service life, must repair and reinforcement deteriorated concrete.At present, concrete reinforcement and strengthening adopts surface to paste fibre reinforced composites more, the fibre reinforced composites (CFRP) that for example carbon cloth and epoxy organic gel form.That CFRP has is high-strength, efficient, the advantage of light weight and easy construction and being used widely, formed the technical system of comparative maturity, China also formulated " concrete structure reinforcement design specification " (GB50367-2006) and " structure reinforcement and repair carbon fiber plate " (GB/T21490-2008).But the epoxies organic gel of pasting use has following defect, (1) softening temperature is lower, generally mostly be 60～80 ℃, under high temperature and fire, can volatilize toxic gas, epoxy radicals can with human body in multiple radical reaction, therefore be conventionally considered to poisonous or carcinogen, this brings great threat to people's the security of the lives and property; (2) meeting accelerated ageing under ultraviolet irradiation, has a strong impact on adhesive property; (3) large with the elastic modelling quantity gap of the concrete material of mineral-type, repeatedly expand with heat and contract with cold and moisture expansion and drying shrinkage cycling condition under, both deformations, easily produce crack, thereby compatibility are poor.For this class problem, application for a patent for invention (CN102351443A, CN201210356357), high temperature resistant alkali slag gel material and preparation method thereof is disclosed, can solve to a certain extent the problem of epoxies organic gel non-refractory, but because its construction method is more loaded down with trivial details, be unfavorable for applying in engineering reality.
[summary of the invention]
The technical problem to be solved in the present invention is to provide the inorganic glue fibrous composite reinforcement of a kind of safety, environmental protection, life-span length and easy construction and protects concrete method.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is, the reinforcement of a kind of inorganic glue fibrous composite and the concrete method of protection, paste inorganic adhesive-fibre sheet material layers of reinforcement at surface of concrete structure, and construction comprises the following steps:
(1) coarse processing is carried out in the surface of concrete component;
(2) inorganic coagulation material is mixed, stirred with water formation inorganic adhesive;
(3) smear one deck inorganic adhesive at the surface uniform of the concrete component of handling well;
(4) on inorganic adhesive fibre sheet material being sticked on;
(5) fibre sheet material is paved, after compacting, exhaust again at fibre sheet material outer surface brushing one deck inorganic adhesive;
(6) if adopt inorganic adhesive-fibre sheet material layers of reinforcement of multi-layer fiber sheet material, repeating step (4) and (5).
Above-described method, described fibre sheet material is unidirectional fiber layers or fiber fabric layer.
Above-described method, described fiber is one or more the combination in glass fibre, carbon fiber, basalt fibre or aramid fiber.
Above method, described inorganic adhesive is phosphate adhesive, phosphate adhesive is by weight, composed of the following components:
Above-described method, phosphate adhesive is by weight, composed of the following components:
Above-described method, described set retarder weight is the 8%-15% of magnesia weight; The weight of water is the 18-25% of phosphate concrete percentage by weight.
Above-described method, described dihydric phosphate is at least one in potassium dihydrogen phosphate, sodium dihydrogen phosphate and ammonium dihydrogen phosphate (ADP), described inorganic mineral filler is at least one in flyash, wollastonite in powder, ground granulated blast furnace slag, steel-making slag powder, kaolin, metakaolin, zeolite, and described set retarder is at least one in borax and boric acid; Magnesia is at least one in reheating magnesia, fused magnesite and seawater magnesia, and the magnesia content in reheating magnesia, fused magnesite or seawater magnesia is not less than 80%.
Above-described method, in step (4) before, soaks fibre sheet material pestle is smash 3～6 minutes putting in inorganic adhesive.
Above-described method, repeating step (4) and (5), inorganic adhesive-fibre sheet material layers of reinforcement of acquisition multi-layer fiber sheet material.
Method of the present invention has improved rupture strength and the impact flexibility of concrete component; inorganic adhesive-fibre sheet material layers of reinforcement has intercepted extraneous corrosive medium to concrete infiltration; the internal material of concrete component is played to reinforcement and protective effect, can extend concrete service life.The elastic modelling quantity of inorganic coagulation material and concrete material approaches, and the harmony of distortion is good, has good interface compatibility, and resistance to elevated temperatures is good, life-span length, safety, environmental protection.Concrete fibrous composite reinforced structure easy construction of the present invention, is convenient to apply in engineering construction with in reinforcing, and has good economic benefit.
