1. Product introduction
TL - 02 type cement concrete pavement patching material, at the base of concrete rapid repair technology at home and abroad
, is a kind of repair mortar specializing in patching road, bridge, passenger railway bridge beam, is developed and manufactured
by our company. Products fully meet concrete repair of high-speed railway,high-grade road,bridge,wharf etc. This product is a kind of one.
component polymer special mortar with early strength properties. It's component including high quality special cement, fine graded silica sand
and imported polymer,inorganic gelled material and a variety of function additives. This material with high early strength,excellent flexibility and
binding power,also meet durability request of high grade road and high-speed rail project.It widely used in concrete pavement structure,
track plate, bridge plate and bridge pier defect repair and reinforcement, especially suitable for concrete pavement, the high speed railway box
girder bridge deck defect repair construction.
2. Application
1).Repair concrete defects of high grade road
2). Repair flatness of high-speed railway and bridge deck
3). Repair and reinforce defects of concrete structure(bridge body, bridge pier or abutment)
4). Repair surface cracking and chip off-falling of concrete beam, load-bearing column and outdoor sheet.
3. Product features
1), simple construction process, just add water then stir.
2).High strength in early and later period: compressive strength of 4h>30Mpa, compressive strength of 1d >50Mpa,
compressive strength of 28d>70Mpa. Bonding strength >2.5Mpa,can meet rapid repair requirement and strength requirement.
3), Good bonding performance: the coating adhesion is strong, concrete mortar can obtain high bonding strength and excellent cohesive force
without interface agent, Anti-freeze thawing, resistance to sulfate corrosion, non-toxic, non-corrosive.
4), Good anti-cracking performance. can adapt to the deformation of the concrete basement without cracking or peeling.
thin layer repairing, no crack, shell, stripping phenomenon.
5). Have good leveling property.
6).Can be used in damp base course and damp environment as first-aid repair material.
