1、 Product Introduction
cement Pavement repair material door For pitted surface, hollowing, peeling, sanding, shelling, cracks, exposed reinforcement, peeling, freezing and thawing of cement concrete pavement gravel Such diseases shall be repaired in a timely manner, which can be directly applied to the diseased parts. It has super compressive strength and bonding strength, which can achieve ultra-thin repair, and will not break and fall off under high-speed and high-pressure driving conditions; All surface diseases of cement concrete are applicable to this material.
2、 Product performance
1. Practical performance
There is no need for complex construction machinery and technical requirements during construction, and there is no need for a long period of closed traffic, and the traffic can be opened in a short time; There is no need to excavate the diseased parts, which can save a lot of construction costs, material costs and maintenance time, effectively delay the spread and spread of road diseases, and extend the service life of the road; Moreover, the color of the repaired cement concrete pavement is close to that of the original cement concrete pavement, with good aesthetics.
2. Bonding property
Using the bonding ability and surface energy principle of the material itself, the repair surface and the original concrete react as a unified whole, thus forming a very high bonding strength. After construction, it can be bonded with various diseased parts. The bonding ability is basically not affected by the thickness, and can achieve 2mm to 5mm ultra-thin repair, without falling off or breaking under the external forces such as expansion, rolling, and pushing.
3. Durability
Fast early performance and high early strength, and no attenuation in the later period, which can eliminate many disease parts at one time; The material itself has strong waterproof, corrosion resistance and direct light prevention capabilities. Its aging relieving ability is more than 5 times that of the original cement concrete. The performance degradation will not be earlier than the original concrete, and the bonding ability and compressive strength will not be lost due to aging.
4. Compressive property
After curing, the repair material has very strong compression and bending resistance. After repair, its strength keeps rising, which has a good reinforcement and support effect on the diseased parts. The repair thickness of 3mm can meet the compression requirements of non special load roads, and it will not break and fall off under high-speed and high-pressure driving conditions.
