Waterproof concrete repair material used in nuclear power station and water conservancy project
TL - 01 type waterproof repair mortar composed by modified synthetic fine sand, coarse sand, concrete, slag, silicon powder and other inorganic material,is a new material for concrete repair. This material have excellent advantages such as: excellent bonding property of epoxy mortar, high strength, waterproof,
resistance to chlorine ion corrosion, convenient maintenance, the expansion and contraction coefficient is almost same with the concrete etc.The product are
widely used in repairing large municipal engineering or other high standard place such as:bridge, wharf, water conservancy, high-speed rail, nuclear power station.
Application
1. Bridges, docks, water conservancy, requiring high strength, waterproof, resistance to chlorine ion corrosion.
2. High-speed rail, municipal bridge, bridge pier, the concrete beam, column, slab, wall body and roof surface repair.
3. Railway or highway lining cracking, hanging piece , restore the structural strength.
4. Concrete honeycomb,pothole,hanging piece,crack.
Product features:
1. 1-2 h open traffic.
3. High bonding strength, high compressive strength.
4. Anti-freeze thawing, resistance to sulfate corrosion, sulfate corrosion resistance,non-toxic, non-corrosive.
4. Has good sagging resistance performance, suitable for facade and top surface operation.
5. Have protective property to steel bar, good durability, also have compact better waterproof anti-permeability.
6. Can be used in damp base course and damp environment as first-aid repair material.
7. Expansion shrinkage coefficient is basically same with base course concrete.
