Concrete road repair material is specially designed for cement concrete pavement repair material, ‌ suitable for all kinds of pavement diseases, ‌ such as pockmarked surface, ‌ hollow drum, ‌ peeling, ‌ peeling, ‌ crack, ‌ exposed reinforcement and so on. ‌ the material has superior compressive strength and bonding strength, ‌ can realize ultra-thin repair, ‌ even in high speed and high pressure driving conditions will not break and fall off phenomenon.
Material properties:
Practical performance
There is no need for complex construction machinery and technical requirements during construction, no need for a long time of closed traffic, and 2 hours after construction can be opened to traffic; 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 roads. Moreover, the color of the repaired pavement is close to that of the original cement concrete pavement, and it has better aesthetics.
Bonding property
Using the bonding ability and surface energy principle of the material itself, the patching surface reacts with the original concrete to form a unified whole, thus forming a high bonding strength. The bonding strength can reach 1.6Mka 2 hours after construction, and it can be bonded with various disease parts. The bonding ability is basically not affected by thickness, and 1mm ultra-thin repair can be achieved. It does not fall off or break under external forces such as expansion, rolling and pushing.
durability
Fast early performance and high early strength, and no decay in the later stage, many disease parts can be eradicated at one time; The material itself has strong water resistance, corrosion resistance and ultraviolet resistance, its anti-aging ability is more than 5 times that of the original cement concrete, the performance decay will not be earlier than the original concrete, and will not lose the bonding ability and compressive strength due to aging.
Compression resistance
After curing, the repair material has very strong compressive and bending resistance, and the compressive strength can reach 22Mka in two hours. In the later period, the strength continues to rise, and the peak compressive strength can reach more than 60Mpa, which has a good reinforcing and supporting effect on the damaged parts. The repair thickness of 3mm can meet the compressive requirements of non-special load roads. It will not break and fall off under high speed and high pressure driving conditions.
