Rapid repair material for cement pavement
The rapid repair material for cement pavement is used for many cement pavement problems, such as potholes, honeycombs, rough surfaces, edge chipping, cracks, sanding, dusting, peeling, hollowing, exposed gravel, etc. If these problems are not repaired in time after they occur, they will quickly develop into diseases. Especially for some diseases of the types of potholes, rough surfaces and exposed gravel, the repair method of digging and patching is basically carried out after the diseases develop to a certain extent, resulting in a large amount of material waste. At the same time, the cost of long - term road closure is also getting more and more attention. The cement pavement repair material of Nanchang Huangteng Building Materials Co., Ltd. can achieve ultra - thin repair, with compressive and bonding strength and durability. The cement pavement repair material can repair the diseased parts in time without long - term traffic closure.
I. Scope of use
Cement pavement repair material is mainly used for the repair of damages such as breakage, honeycombing, pockmarks, sanding, peeling, exposed aggregate, freeze-thaw, and fine cracks on cement concrete pavements of highways, toll stations, service areas, gas stations, airports, bridge expansion joints, factory floors, and rural roads. The cement pavement repair material can enable the road to be reopened to traffic within 2 - 3 hours after repair.
II.Product Features
1. It cures quickly at room temperature, and the road can be opened to traffic 2 - 3 hours after pavement repair.
2. It has an alkaline system, which has good compatibility with cement and does not corrode steel bars.
3. It is non - flammable and convenient for storage and transportation. Cement pavement repair material.
4. It has strong adhesion, anti - peeling property, excellent durability, and its coefficient of thermal expansion is close to that of concrete.
5. It can restore the original performance of the concrete pavement and at the same time have good impermeability.
6. Freeze-thaw resistance, *** resistance, and *** resistance (*** and snowmelt agent resistance).

Practical performance
When constructing the cement pavement repair material, no complex construction machinery and technical requirements are needed, and no long - term traffic closure is required. The traffic can be opened two hours after construction. There is no need to excavate the damaged parts, which can save a large amount of construction costs, material costs and maintenance time, and significantly delay the spread of road diseases and extend the service life of the road. Moreover, after repair, the color of the cement pavement repair material is close to that of the original cement concrete pavement, with good aesthetics.
Bonding performance
The cement pavement repair material utilizes the bonding ability of the material itself and the principle of surface energy. The repair surface reacts with the original concrete to form a unified whole, thus forming a high bonding strength. The bonding strength can reach 1.8Mpa 2 hours after construction. It can bond with various disease parts, and the bonding ability is basically not affected by the thickness. The cement pavement repair material can achieve a 3mm ultra-thin repair, and will not fall off or break under external forces such as expansion, rolling, and pushing.
Durability performance
The cement pavement repair material shows relatively fast early performance and high early strength, and the strength does not decline in the later stage. The material itself has strong waterproof, *** and anti-ultraviolet abilities. Its anti-aging ability is more than 4 times that of the original cement concrete. The performance decline will not be earlier than that of the original concrete. The cement pavement repair material will not lose its bonding ability and compressive strength due to aging.
Compressive performance
After the cement pavement repair material is cured, it has strong compressive and flexural abilities. The compressive strength can reach 22Mpa in two hours, and the strength continues to increase in the later stage. The peak compressive strength reaches over 80Mpa, which has a good reinforcement and support effect on the disease parts. A repair thickness of 3mm can meet the compressive requirements of non-special vehicle load roads. The cement pavement repair material will not break or fall off under high-speed and high-pressure driving conditions.
4. Product Packaging
Each bag is 25KG.It is packed in composite kraft paper bags, 25kg per bag, with a shelf life of6 months.
It must be stored in a dry and ventilated indoor area, with the packaging bag sealed. Pay attention to moisture and frost protection.
5. Construction Temperature
The construction temperature must be above 0 degrees. It is recommended to construct above 5 degrees.
Construction is prohibited in strong winds, heavy rains, and heavy snow.
