Product Description:

Bridge Bearing Grouting/Non-SHrink Cementitious grout

YH-GJ bearing mortar is used for railway bridge bearing installation of high quality cement base composite materials.Because of its USES a variety of high performance additives, special smooth surface flat after completion.To overcome the traditional mortar uneven, shortcomings and so on crack, flake, self-leveling, high early strength, high strength, no shrinkage, high wear resistance and construction is convenient wait for a characteristic.The performance indicators meet the passenger dedicated line bridge pot rubber bearing interim technical conditions, such as national and industry standards and technical requirements.
Method of use:
0.15 according to water than to join uniform mixing grouting can be used directly.
The construction method
Will be cleaned up at the grassroots level to remove floating dust, oil spots such as adhesive material.Before construction, basic use tap water to wet, cannot leave MingShui when pouring cement mortar.
According to the construction area and construction area per unit time to calculate powder feed rate and water use, guarantee the mortar in lost all before flowing property construction completion.
Add water to mixing barrel, and then gradually add said good self-leveling material, simultaneously stirring, until the required material all adds, continue to stir 2 to 3 minutes, make the paste evenly, let stand 1 minute or so.
Will be treated as mixing the filtered pulp evenly to the good ground, self-leveling.Flow leveling construction time is best done in 30 minutes, after construction machines and tools or rinse.
With an electric mixer mixing powder, it is best to use a gun stirring, large-scale construction of using mortar mixer.
Range of application
YH-GJ production support grouting material is suitable for the repair, orbital filling, pedestal grouting, especially suitable for high speed railway bridge bearings or orbital filling etc.Can also be used for concrete beam local leveling or repair of the concrete pier.

Q:Is the polymer cracked mortar and polymer bonded mortar the same?
Is the introduction of foreign technology companies to join the status of China's insulation, the use of 42
Q:Who knows the inorganic insulation mortar and the previous material What is the difference?
Good durability, good weatherability good hydrophobicity, strong vapor permeability high refractory grade, non-combustible good adaptability, easy construction, Speed, a comprehensive technology, practice diversity green, non-polluting, non-radiation ecological building materials Disadvantages: the current implementation of the standard is GB-2006 "building insulation mortar", this standard is the material standard, there is no specific system standards.
Q:Insulation putty can be used alone as an external wall insulation material? Whether the external wall insulation putty can replace the external wall mortar
Under normal circumstances need to use with the insulation materials
Q:Brick and concrete structure and frame structure in the force system, the use of building materials and the scope of the three aspects of the difference. Thank you ~ ~ very anxious
Masonry structure: gravity load transfer floor, roof panel → wall → foundation → foundation → crust
Q:What materials do the bathroom waterproof anti-leakage ah? Do not use cement directly?
With cement is certainly not work, if the bathroom caissons and sidewalls need to use a different waterproof material, caisson is best to use polyurethane type, like CQ101 is the best use of caissons, but the side wall you can not use CQ. because the side wall with CQ. then you are sticky instability tiles, it can only use JS, that is, CQ. CQ101 and CQ105 is a brand of models, specifically what I do not say. Long-term soaked with the best polyurethane, such as the caisson belongs to this category; over the water on the best use of JS, the side wall is Dan often grass end of the whole factory households like this! Pure hand to play, hope to adopt.
Q:Whether the mortar waterproofing agent needs to be sampled for inspection
need According to the specification, the admixture of the approach must have the certificate and the product instruction manual, and then need qualified laboratories according to the proportion of the manual, the trial test, the performance is qualified before allowing the use of construction
Q:Do you install firewood in the door frame when installing fire doors?
If there is no local norms, issued a separate request, then refer to the national standard atlas "fire doors and windows" to carry out; . the door frame to be filled with non-combustible materials, see note; . 30 album, filler C20 concrete
Q:M15 in the building that the strength of mortar? What is the unit?
Feldspar feldspar is a broad name of basic aluminosilicate, for example: feldspars containing alkali metal potassium (potassium oxide-alumina-silica) are called "potash feldspar" and contain Sodium (sodium oxide - alumina - silica) feldspar is called "albite", but most feldspars are made from these two types.
Q:Wall plastering works: why gypsum ash should not be wiped in the cement mortar layer
Cement mortar in the wet weather, the water coagulation on the surface, lime paste water condensation in the inside, the two easy to delamination, so lime paste under the grass, are used cement lime mortar The shrinkage of the material is different Lime mortar Suxian light liver scalled Fei Gui ten ginger water, will affect the strength of cement mortar Lime is not fully hydrated lime will be the top cracked plaster Lime mortar for a long time there is the possibility of precipitation of calcium carbonate This will be layered
Q:Bathroom wall brush flexible waterproof, stick wall bricks easy to fall off after it? Is not tiling cement to add 901
Not necessarily, this specific situation you need according to the nature of your waterproof paint at that time to decide your next construction material. If you are not very understanding of this line, it is recommended that you information professional construction workers, workers long-term exposure to a variety of waterproof materials, the material properties of which is relatively more than the Shanghai high-crossing fishing for more familiar with each other. So, the information field workers will be better.
