Description
Technical field
The present invention relates to a kind of repair materials for repairing damaged concrete or bituminous pavement fast and preparation thereof and constructional method, belonging to recovery technique field, road surface.
Background technology
Hard surface generally adopts the materials such as concrete, pitch, resin concrete.May be there is the defects, particularly airstrip such as damaged in use procedure, working conditions is badly particularly more easily damaged wartime.Need one can meet use properties, the material well can repaired at short notice again with starting materials compatibility performance and constructional method.
The material display of open report: repair materials and the constructional method thereof of repairing now damaged concrete (pitch) road surface have several as follows:
First; Normal concrete is exactly take cement as consolidating material, and husky, stone is the formulated artificial stone-like material that mainly gathers materials.This material has long use history, and its use properties can meet service requirements, but set time is long, is difficult to meet the requirement of repairing fast;
Second; Gather and thing modified concrete.Be prepared into cement material special additive with poly-and thing glue exactly, improve the bonding capacity of cement, strengthen cohering between gathering materials, the Performance Ratio normal concrete that is poly-and thing cement concrete after sclerosis is good.But poly-and thing cement concrete solidifies under normal temperature condition, setting time is difficult to control, and in order to ensure to gather, its setting time comparatively needed than normal concrete is long usually with thing cement concrete use properties.
Three, airstrip reparation, the formed material such as glass epoxy, metal sheet etc. is laid in the employing abroad also had at present.This needs to stock the formed materials such as a large amount of glass epoxies, metal sheet.Carry out processing and splicing at construction process, it can only connect by the method such as cohering, inlay with body material.
Disclosed " a kind of polymer concrete for airfield runway quick renovation and preparation method thereof " this polymer concrete of Chinese patent literature CN1923484 with industrial waste flyash and sandstone for main raw material, take epoxy resin as binding agent, modified multicomponent amine is solidifying agent, add appropriate activity dilution toughner simultaneously, formulated by a certain percentage, the proportioning of these five kinds of raw materials is counted by weight, is followed successively by (150 ~ 200): 100: 100: (15 ~ 30): 15.The polymer concrete material utilizing the present invention to prepare have setting rate fast (5 ~ 30min set time), early strength high (compressive strength 65 ~ 83MPa), strong with the cohesive force of cement concrete, can construct under the condition of moist, low temperature, cured article intensity is high, good toughness, surfacing, wear resistance and shock resistance excellent.This material is mainly used in the quick reparation after airfield runway damage, also can be widely used in the emergency maintenance of the concrete workses such as building, road, harbour, tunnel.
But above-mentioned polymer concrete, engineering time requirement controls at 5 minutes, repairs on a large scale and is difficult to ensure, just may solidify at agglutinate with (flyash and sandstone) mixing process of gathering materials; Its two, such polymer concrete surface is Self-leveling, and the degree of compactness of polymkeric substance can not be guaranteed; The planeness of runway also can not be guaranteed.
CN103951359A disclosed " a kind of high-performance road rehabilitation king material ", comprises following component: the strong aluminosulfate cement of superelevation: 20-60 part; Polycarboxylic acid series high efficiency water reducing agent: 0.1-1.2 part; Ferric oxide: 0.2-3.5 part; Retarded adhesive material/efficient short hard accelerating chemicals: 0.1-1.5 part; Quartz sand: 35-68 part; High-elasticity putty powder: 1-12 part; Building macromolecular material: 0.1-3 part, this material feedstock composition is complicated, and cost is high.
Summary of the invention
The present invention is directed to the deficiency that existing road recovery technique exists, there is provided a kind of over-all properties and consistency is good, working life is long, the damaged road surface material for quickly repairing that setting time is controlled, provides a kind of constructional method of this material simultaneously, to reach the effect of reparation fast.
Damaged road surface material for quickly repairing of the present invention, comprises agglutinate, gathers materials and steel fiber; Agglutinate, to gather materials and the weight ratio of steel fiber is: 1 ~ 2:6 ~ 8:1 ~ 2.
Described agglutinate, be the mixture of epoxy resin, solidifying agent and promotor, its epoxy resin accounts for the 48%-94% of gross weight; Solidifying agent accounts for the 4%-50% of gross weight; Promotor accounts for the 1%-5% of gross weight.Described epoxy resin is bisphenol A type epoxy resin.Described solidifying agent is sex change amine curing agent of hiding.Described promotor is tertiary amine or tertiary ammonium salt.
The sandstone of the described 0.1mm-20mm that gathers materials that to be particle diameter be.
After solidifying agent and promotor coordinate with epoxy resin in the present invention, at room temperature can place the long period, more stable, working life is long, heating and microwave radiation compound action under can cause solidification fast, make epoxy resin be cross-linked into cured article at controlled condition.Epoxy resin, originally as thermoplastic linear structure, must add solidifying agent, carry out polyreaction under certain condition, could apply after generating network is Structured cured.For ensureing that the present invention sets epoxy lipopolymer consolidating material and has certain working life, therefore use sex change amine curing agent of hiding.By promotor, in the reaction of specified conditions fast curing additives and epoxy group(ing).
Steel fiber can adopt any metallic substance to make, and has following effect:
1. make the toughness of material for quickly repairing improve, flex resistance is improved.
2. steel fiber improves the conduction of material for quickly repairing heat in heat-processed.
In solidified polymeric concrete setting process of the present invention be heating and microwave radiation compound condition under carry out, polymer concrete is organic synthesis thing, its thermal conductivity is doubly a lot of lower than metallic substance, and the transmission of heat is directly proportional to thermal conductivity, adding of steel fiber, be equivalent in polymer concrete, erect heat conducting network, improve heat to transmit in polymer concrete, accelerated solidification polymer concrete, and by controlling the number of steel fiber, controlling heat conducting network density and controlling rate of heating.
3. steel fiber also has the effect of microwave radiation at polymer concrete process of setting.Microwave irradiation can all reflect to metallic surface, inoperative to metal.But microwave action is in polymer concrete, it is nonmetallic dielectric substance, dielectric substance characteristic determines that microwave will be absorbed, permeates, produce high-frequency electric field and magnetic field, the frequent athletic meeting of the intermolecular electron pair of alternation high-frequency electric field effect produces vibrations and causes molecular friction and produce heat, in polymer concrete, steel fiber can cause spark discharge in high-frequency electric field and magnetic field, can the carrying out of secondary heating process.
The preparation method of above-mentioned damaged road surface material for quickly repairing, comprises the following steps
