JW non-shrinkage ultra-high strength road repair agent (mortar)
Classification:
Detailed introduction
JW non-shrinkage ultra-high-strength road repair agent (mortar) is a special engineering material developed independently by relying on the company's technical resource advantages under the guidance of relevant experts from the National Institute of Building Materials. It not only has no shrinkage, high early strength, good wear resistance, strong bonding force, superior impermeability and frost resistance, but also has certain micro-expansion performance. It is a new type of material developed for repair engineering and road repair concrete defect repair, which is ahead of similar products in China.
Performance characteristics:
1 early strength is very high, 3 small age compression can reach more than 30MPa, higher in summer. And the late strength does not shrink, the 28-day compressive strength can reach about 80MPa, and the flexural strength is also very superior, reaching about 13MPa in 28 days.
2 volume stability, compact structure, 28 days does not shrink and there is a certain micro expansion effect.
3 good wear resistance, airport runway, highway repair, are ideal materials.
4 This material does not contain radioactive substances and other corrosive materials harmful to the human body, and there is no need to worry about the erosion of steel bars.
5 convenient construction, site construction, add quantitative water mixing can be used.
6 excellent working degree, good workability and viscosity, strength is more than twice that of ordinary silicon cement.
Scope of application:
Airport runway and highway rapid repair, 4 hours to reach the normal use standard.
Bridge and road expansion joint repair, and rigid pavement holes and local repair.
Rapid fixing of telegraph poles and other stakes.
1. secondary grouting of mechanical equipment base, etc.
Other civil engineering requirements for early setting and early strength can be met.
Note:
1 China has a vast territory, and the climate contrast has a certain impact on the construction. It is suggested to do the setting time control experiment before construction. If the setting time is too fast, cold water can be used as mixing water when slowing down the setting. If the setting time is slow, it can beMix the water with hot water.
2 The scene to be constructed shall be kept in a clean state, and the surface of the concrete interface to be followed shall be kept free of attached moisture.
3 after construction can be water conservation.
4 proportion of repair agent with mortar:
Repair agent: sand (20~80 mesh) = 1:1.0~1.2. In case of large volume hole is too deep, sand can be added:
Coarse aggregate = about 1:0.8 gravel, of which the diameter of gravel should be above φ10mm, which will not affect the work and various performances.
Packaging and storage:
1 This product is 25kg or 50kg sealed plastic packaging.
2 storage, should be placed in a cool, dry place, to prevent moisture and damage.
3 The shelf life can be placed for more than 6 months under normal conditions.
