High Drawing strength bridge deck surfaceing hole broken repair mortar
product characteristics
Deck concrete repair material (QM-type) is a single-component special repair material that simple construction, high strength, good toughness, adhesion super, not broken at high speed, high pressure, impact and non-driving status off.
Fundamentally done to restore concrete pavement strength and integrity, greatly extending the concrete pavement and bridge deck expansion joints of life, to solve the bridge construction leads to traffic congestion problems! At the same time the quality of repair guarantee and meet the durability requirements of highway, national highway, provincial highway!
the product 8 big advantage
A fast recovery of traffic: for high-speed, national, provincial, municipal, airports and other transportation can be achieved 1--2 hours.
2, high compressive strength: 1h more than 25Mpa, 2h more than 35Mpa, 1d more than 60Mpa, 28d more than 80Mpa.
3, high flexural strength: 1h greater than 5Mpa, 2h greater than 7.5Mpa, 1d more than 10Mpa, 28d more than 11Mpa.
4, good adhesion properties: bond pull strength reaches 2.8Mpa, to solve the traditional material bond is not strong or problems can easily lead hollowing cracks.
5, the product toughness and impact resistance: 5-10 times that of ordinary concrete.
6, the thermal expansion coefficient: basically consistent with the primary concrete.
7, no shrinkage cracks: between the original concrete and no shrinkage cracks after solidification.
8, frost and salt corrosion: cold-resistant, corrosion-resistant sulfate, non-toxic, non-corrosive.
the construction method :( graphic combination)
Construction process:
Traffic Control → Logo → crossed → kerf → chiseled scour → cleanup cleanup → protection → spices → Patch → slitting → conservation → relieve traffic control

Notes:
1. The cement concrete pavement repair materials for the early strength materials, operative time is usually less than 15 minutes; user needs based on the operating time adjustable material; hardened mortar is strictly prohibited.
2. Add clean diameter ≤30㎜ graded gravel aggregate, the ratio was 50%.
3. Construction of the summer has been good repair area surface should prevent exposure, can be patched plastic film covering the surface area;
4. Winter conservation should pay attention to insulation, hot water can be stirred and stamped with rockwool insulation, the temperature is below 5 ℃, or wind or rain can not be greater than 5 construction.
