Description
Technical field
The present invention relates to the concrete restorative procedure of water and soil building surface, specifically relate to surface concrete aging, the carbonizations of hydraulic structures such as ship lock, dam, bridge, peel off the restorative procedure of cracking.
Background technology:
Concrete structure is one of form of structure that is most widely used in the field of civil engineering.But, badly influence its functional performance and life-span because the defective and the combined influences such as match ratio, maintenance, construction environment and service factor thereof of concrete material itself cause a lot of cement-based material performances to descend.And the concrete for hydraulic structure structure is owing to be subjected to washing away of current erosion and silt carrying flow for a long time, the destruction that is suffered is more remarkable: 22 the coastal hydraulic structure investigation in Zhejiang in 1984 are found, what heavy damage had been passed into disuse has 3, operation only 8～10 years, infringement is serious be badly in need of overhaul have 8, local damage have 8; Unit such as Hohai University eighties, the survey showed that to the mode of occupation of domestic hydraulic structure, port and pier etc., the hydraulic structure that used 10～30 years has nearly 60% corrosion of steel bar destruction to occur, and the sea port dock that used 7～25 years has nearly 90% corrosion of steel bar destruction to occur; " China's corrosion survey report " book of publishing recently shows that the year corrosion loss of China is about 5,000 hundred million yuan (60,000,000,000 dollars) and accounts for 6% of GDP.Because the structural deterioration that causes of concrete durability problem is serious and bring enormous economic loss; therefore study the repair materials of function admirable, reparation and the improvement work that repair in the crack, repairing, reinforcing bar anchoring, antiscour structure protective layer etc. are degraded in freeze thawing of carrying out concrete structure are very significant.
Carried out number of research projects for the reparation of building concrete structure with improvement work people, but be subjected to characteristics such as high speed silt carrying flow erosion for a long time at hydraulic structure, about its high-strength and high performance (wear-resisting crashworthiness), high impervious and few with specializing in of the firm repair materials of old wall bonding.As owing to reasons such as natural carbonization and high speed silt carrying flow erosions, operation ship lock, dam for many years can occur surperficial concrete spalling, the carbonization of large tracts of land nature, base plate and gallery mostly and be subjected to the current erosion to cause damaged phenomenons such as revealing stone, the safety and the application life of ship lock hydraulic structure have been badly influenced, traffic and hydraulic department are being explored concrete wall surface repairing and reinforcing technology for many years always, still do not have more perfect processing method so far.
Because fiber has good toughness reinforcing, cracking resistance, wear-resistant effect, chopped strand is used for strengthening mortar concrete, fiber can improve toughness, tensile strength and the flexural strength of cement matrix by the bridge joint crack, make cement concrete product intrinsic fragility problem improved greatly.At present in the fibrous concrete research more steel fibre, polypropylene fibre etc. are arranged.But the cost of steel fibre is higher, than great, be not easy to disperse, be unsuitable for cement in routine and strengthen in the goods and act on.Though polypropylene fibre can be dispersed in the concrete, chemical property is stable, construction is simple, also has the price height, and intensity and modulus are low, with defective such as cement matrix bad adhesion.
Summary of the invention
The object of the present invention is to provide a kind of method with the high-strength abrasion-proof basalt fibre mortar rehabilitating concrete surface injury.
With the method for high-strength abrasion-proof basalt fibre mortar rehabilitating concrete surface injury, it is characterized in that the step of restorative procedure is as follows:
1, the processing of repair surface:
(1) cutter hair in surface is handled: adopt artificial or mechanical method that repair surface is cut a hole hair and handle, help strengthening adhesion stress;
(2) removing surface: at first adopt gases at high pressure to blow a time, water then to clean the top layer is cleaned out;
(3) maintenance is preserved moisture: repair surface water seasoning 24h preserves moisture;
2, preparation high-strength abrasion-proof basalt fibre mortar, cement, sand, water, high efficiency water reducing agent and basalt fibre are made by following weight proportion: cement 100, sand 120～150, high efficiency water reducing agent 0.6～1.0, basalt fibre 0.1～0.2, water 20～30, unit of weight is gram or kilogram.
Cement, sand, water, high efficiency water reducing agent and basalt fibre by preparing in above match ratio scope, are stirred, stand-by;
3, brush bonding agent: adding additives can increase the repair layer adhesion strength, and even brushing cementing agent on tack coat at first whitewashes the high-strength abrasion-proof basalt fibre mortar of above-mentioned preparation after dried slightly again;
4, whitewash and maintenance: the step of whitewashing repairing mortar may be summarized to be: " one is coated with two flat three press polish ", after promptly 1 metope reparation is finished, in 5 hours, to carry out smearing for 1～3 time the light work of receiving that flattens, carry out maintenance with the method for spraying or topped plastic sheeting after whitewashing, then by repair remaining metope with quadrat method.
Sand described in the above-mentioned steps 2 is hard thick quartz sand, and its fineness modulus is 3.7～3.1, screens out wherein the particle greater than 5mm.
High efficiency water reducing agent described in the above-mentioned steps 2 is naphthalene sulfonic acid-formaldehyde condensation product or melamine sulfonate and formaldehyde condensation polymer, and the water-reducing rate of water reducing agent is 20%～25%.
Basalt fibre described in the above-mentioned steps 2 is the short basalt fibre, its density 2.6～2.8g/cm cut
3, the modulus of moving 93.1～110Gpa, fracture elongation 3.2%, water imbibition＜0.5.
Cementing agent described in the above-mentioned steps 3 is that clean slurry of third breast or silica flour are starched only.Wherein the weight proportion of the clean slurry of third breast is third breast: cement=1: 2.5; The weight of the clean slurry of silica flour is joined and is cement: silica flour: water=0.34: 0.056: 1.
Beneficial effect
Good characteristic such as novel basalt fibre (Basalt Fiber is called for short BF) material has the tensile strength height, modulus of elasticity is big, corrosion-resistant and chemical stability is good.The present invention cuts weak point that basalt fibre is used for repairing mortar preparation high-strength abrasion-proof basalt fibre mortar it is toughness reinforcing to give full play to first, cracking resistance, wear-resistant effect.The evidence high-strength abrasion-proof basalt fibre mortar can effectively reduce the shrinkage performance of mortar, have mechanical property such as good tension, bending resistance and good anti-impact mill property, durability such as impervious, freeze proof, and adhesive property is good.The high abrasion of this repairing mortar, high impact properties can satisfy the anti-sand current of holding under the arm at a high speed and denude and be subjected to technical requirementss such as ship collision, reparation for ship lock, the base plate that rushes down hydraulic structure surface concrete spallings such as big vast dam, flood spillway bridge, the impaired and impaired dew stone of large tracts of land carbonization and gallery etc. provides the restorative procedure that a kind of technology is simple, cost is low.
