Abstract
The invention relates to a road pavement rapid-repairing material and belongs to the technical field of building materials. The road pavement rapid-repairing material comprises: by weight, 17 to 23% of portland cement, 3 to 6% of hydroxypropyl methylcellulose, 1 to 2% of fatty acid butyl ester, 4 to 9% of re-dispersible latex powder, 13 to 22% of semi-hydrated gypsum, 14 to 25% of limestone flour, 4 to 6% of sodium tripolyphosphate, 4 to 6% of polyacrylamide, 2 to 5% of sodium silicate, 5 to 7% of triethanolamine and 3 to 6% of polyvinyl alcohol. The road pavement rapid-repairing material has the advantages of fast curing rate and strong pavement strength.
Description
Technical field
The present invention relates to a kind of highway Rapid-Repair ground surface material, belong to building material technical field.
Background technology
At present, along with the highway in China construction speed constantly speeds, need to keep in repair with the road area of maintenance also more and more.Most road surface employing concrete or bituminous material when fracture or breakage occurring, need in time be repaired, otherwise can affect the safety of driving.In order to guarantee to have a good transport and communication network, the repairing of road pavement need to be finished fast, and this just requires the road pavement patching material to have higher requirement, and not only wants to reach fast setting, more certain intensity will be arranged.
Patent CN101717234A discloses a kind of quick patching material for cement concrete pavement, includes slag powders, water glass, Sodium Silicofluoride, desulfurated plaster, rosined soap, regeneration concrete fine aggregate etc.But this ground surface material can cause the rigidity of ground surface material strong, nonelastic, and ftractureing again in the road surface after duration of service, length can cause repairing, affects pavement quality.
Therefore, need to provide a kind of ground surface material of can the Rapid-Repair road surface and having better intensity.
Summary of the invention
For above problem, the invention provides a kind of highway Rapid-Repair ground surface material, not only curing speed is fast, and has high-intensity characteristics.
The technical scheme that adopts is:
A kind of highway Rapid-Repair ground surface material, the component that comprises following weight percent meter: silicate cement 17～23%, Vltra tears 3～6%, fatty acid butyl ester 1～2%, redispersible latex powder 4～9%, semi-hydrated gypsum 13～22%, limestone powder 14～25%, tripoly phosphate sodium STPP 4～6%, polyacrylamide 4～6%, water glass 2～5%, trolamine 5～7%, polyvinyl alcohol 3～6%.
The preparation method of above-mentioned highway Rapid-Repair ground surface material is:
The preparation of mixture A:
Take by weighing by weight tripoly phosphate sodium STPP, polyacrylamide, water glass, trolamine and polyvinyl alcohol, place nonmetal window to stir, sealing is preserved, and gets mixture A.
The preparation of mixture B:
Take by weighing by weight silicate cement, semi-hydrated gypsum, limestone powder, mix.Add again by weight Vltra tears, lipid acid fourth fat, redispersible latex powder, again mix, get mixture B.
When construction, at first at the construction field (site) adding among the mixture B is made slip by the water of the 15-25% of mixture B weighing scale, in slip, add mixture A again, mixing 1 hour was constructed in impaired highway in 1 hour again.
Further preferred version includes the component of following weight percent meter: silicate cement, silicate cement 23% in the above-mentioned ground surface material, Vltra tears 6%, fatty acid butyl ester 2%, redispersible latex powder 8%, semi-hydrated gypsum 13%, limestone powder 24%, tripoly phosphate sodium STPP 5%, polyacrylamide 4%, water glass 4%, trolamine 5%, polyvinyl alcohol 6%.
Highway Rapid-Repair ground surface material provided by the invention, it is fast to have a curing speed, the advantage that pavement strength is high.
