The diseases such as sound strengthens, expansion joint leaks, adhesive tape corrosion, cause strong influence to the serviceability of bridge, have a strong impact on bridge
Life-span and travel safety.Bridge expanssion joint in using is carried out maintenance timely, quick, maintenance, is to ensure that bridge structure
Stably, guarantee driving safety is than indispensable link.
Current domestic normal use C50 normal concrete pours bridge and stretches, but this concrete coagulating time length, early strength
Low and old concrete interfacial bond property is poor, shock resistance is general, cannot meet timely to bridge expanssion joint, quick at all
Maintenance and the basic demand of maintenance.Therefore, need exploitation one badly and be exclusively used in bridge expanssion joint recovery project, and there is early strength
The superior material for quickly repairing of height, interfacial bond property excellence, good volume stability, shock resistance is to bridge maintenance, dimension
Industry of practicing Buddhism or Taoism important role.
Summary of the invention
The technical problem to be solved is to provide a kind of early strength height, interfacial bond property is excellent, volume is steady
Qualitative good, the polymer material for quickly repairing repaired for bridge expanssion joint that shock resistance is superior.
For solving the problems referred to above, a kind of polymer for bridge expanssion joint reparation of the present invention quickly repairs material
Material, it is characterised in that: this material is made up of siccative and liquid material two parts；After described siccative is mixed by the raw material of following mass parts
Stir, and be packaged in gained in moisture barrier bag: SAC cement 60 ~ 70 parts, mineral admixture 3 ~ 3.5 parts, compound additive 0.6 ~
0.7 part, quartz sand 25.8 ~ 36.4 parts；Described liquid material is in being individually packaged in Plastic Drum and account for described siccative gross mass 10 ~ 20%
PM-1 latex.
Described SAC cement refers to that no more than 10min setting time, basicity are more than 10.5 and are numbered the early-strong-fast-hard of 42.5
Sulphate aluminium cement.
Described mineral admixture is power plant's first level flour coal ash.
Described compound additive refers to by the high efficiency water reducing agent accounting for described SAC cement quality 0.4 ~ 0.5%, accounts for described SAC water
The early strength agent of shale amount 0.08 ~ 0.12%, account for the mixture that the retarder of described SAC cement quality 0.5 ~ 0.6% mixes；Institute
State early strength agent and refer to that lithium chloride is mixed by the mass ratio of 1:1 with calcium nitrite；Described retarder refers to sodium tartrate, wood
Calcium, Borax are mixed by the mass ratio of 1:1:8.
Described quartz sand refers to the quartz sand that particle diameter is 0.5 ~ 1mm and the quartz sand mass ratio by 1:1 that particle diameter is 1 ~ 2mm
Mix.
Described PM-1 latex refers to that SBR latex is mixed by the mass ratio of 100:0.5 ~ 0.8 with 2706 defoamer.
The application of a kind of polymer material for quickly repairing repaired for bridge expanssion joint, its feature exists
In: mix thoroughly after siccative, liquid material are mixed by 100:10 ~ 20:10 ~ 16 mass ratio with drinking water.
The present invention compared with prior art has the advantage that
Early strength of the present invention height, interfacial bond property excellence, good volume stability, shock resistance are superior, and can realize
Bridge expanssion joint is quickly repaired, and 6h open to traffic, 3d ~ 7d exceed cement normal concrete 28d intensity, can be exclusively used in bridge maintaining
The reparation of old bridge expanssion joint and again pour (seeing table 1) in improvement project.
