Which repair material is best for cement pavement repair

The best materials for cement pavement repair are concrete repair mortar and cement pavement sanding treatment agent, which are described as follows:

1. Concrete repair mortar, this material can be a good repair of pavement sanding, hemp surface, potholes, the appearance of the pavement after repair changes greatly, but the cost of using this material is relatively high, 2, cement pavement sand treatment agent, which is based on the hardener for formula upgrading, specifically for concrete pavement sand and research and development of a new material, cement pavement sand treatment agent is a water-based material, it can quickly improve the strength of concrete pavement, solve the pavement sanding, but can not change the appearance of the ground.

3. After repairing with this material, the strength of the pavement is improved quickly, and the iron nails can not be scratched on the same day of repair, and compared with the hardener, the pavement repaired with this material is not afraid of rain erosion.

4. Compared with the traditional mortar repair, under the premise of ensuring smooth delivery and ensuring the normal use of the pavement in the next three to five years, the repair cost can be reduced by at least 45% with Guheng cement pavement sand treatment agent.

Notes:

1. After cleaning the cracks, there is an indispensable step that is crack flushing, which is a step that is easy to be ignored by many people and skipped.

2. In the process of repairing cement pavement cracks, we should also pay attention to different cement pavement crack repair materials, and there will be certain differences in the proportion of water added, and we should operate in strict accordance with the material instructions.

BC type cement pavement repair material:

SC repair material: suitable for cracks, pits, expansion joint damage, edge gnawing, broken corners, etc., the bonding is relatively firm, the color difference is small, and it is basically open to traffic in 1 hour.

Heavy-duty cement pavement repair material: chemical properties of silicate-based modified polymer suitable for exposed stones, freeze-thaw and other diseases, large friction coefficient, frost resistance, 1 hour final setting.

Concrete Structural Repair Material: Chemical Properties: Silicate-based Modified Polymer.

Pay attention to what type of pavement generally has special repair materials, and the key after repair is regular maintenance.

Practical performance. There is no need for complex construction machinery and technical requirements during construction, no need to close traffic for a long time, and traffic can be opened 24 hours after construction; 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 prolong the service life of the road; Moreover, after repair, it is close to the color of the original cement concrete pavement, and has a good aesthetics.

Adhesion properties. Using the adhesion ability and surface energy principle of the material itself, the repair surface reacts with the original concrete into a unified whole, so as to form a high bonding strength, the bonding strength can be reached within 24 hours after construction, and can be bonded with various disease parts, and the bonding ability is basically not affected by the thickness, and can realize 1mm ultra-thin repair, which will not fall off or break under external forces such as telescopic, rolling and pushing.

Durability. Faster early performance and higher early strength, and no attenuation in the later stage, can be one-time for many disease parts; The material itself has strong waterproof, corrosion resistance and ultraviolet resistance, and its anti-aging ability is more than 5 times that of the original cement concrete, and the performance attenuation will not be earlier than that of the original concrete, and it will not lose its adhesion ability and compressive strength due to aging.

Crush resistance. After curing, the repair material has a very strong compressive and bending resistance, the compressive strength can reach 22MKA in 24 hours, and the strength continues to rise in the later stage, and the peak compressive strength is more than 100MPa, which has a good reinforcing and supporting effect on the diseased parts, and the repair thickness of 3mm can meet the compressive requirements of non-special load roads, and will not be broken and falling off in the high-speed and high-pressure driving state.

Cement pavement repair with Guheng concrete fast repair treasure is better, the main reasons are in the following two points;

Guheng concrete fast repair treasure is a high-strength concrete repair material, with this material after the repair of cement pavement can reach the strength of C40 concrete, even if the repair of 5mm, about 20 tons of heavy vehicles perennial rolling, the pavement will not appear within 5 years of any cracking and delamination problems.

Since Guheng Concrete Quick Repair Treasure is the masterbatch of cement pavement repair material, 1 ton of concrete Quick Repair Treasure can be added to tons of sand to become a finished material.

Therefore, at present, most construction units and factories are using this material for overlay repair.

Cement pavement repair material 1600-2000 a ton, professional technical guidance.

Look at the damage to the cement pavement.

Product performance of Lumei new material building materials:

If you need to speed up the curing speed in loose culture, you can add a small amount of fast hardener or other accelerators. Please note, however, that safe handling protocols should be followed when using and protective gear should be worn if necessary.

What kind of cement is used for rapid repair cement, which kind of additives are used, and natural sand or machine-made sand is used for sand.

Pro-fast repair cement generally uses high-strength fast-hardening cement, such as No. and No. cement. These cements can reach the required strength and hardness more quickly, improving construction efficiency and repairing the efficiency of the burner. For the choice of additives, different additives can be selected according to the specific situation.

For example, if you need to speed up the hardening of cement, you can add an early strength agent or a fast hardening agent; If it is necessary to improve the crack resistance and durability of the repair material, additives such as modified polymers can be added. As for the selection of sand, manufactured sand or natural sand that meets the standard specifications should be selected to ensure the quality and service life of the repair material. When choosing sand, factors such as particle size distribution, particle shape, and surface finish need to be considered.

In general, manufactured sand or fine sand is more suitable for the use of rapid repair cement.
