Concrete pavement repair materials? Who knows?

Concrete pavement repair materials are mainly used for rapid repair of concrete pavement sanding, peeling, hemp surface, potholes, exposed stones, cracks and other diseases, concrete pavement repair materials on the market;

One is the cement pavement repair material (finished material), after buying back, it can be used directly by adding water in proportion and stirring into mortar, but because the use cost of this material is relatively high, the material adhesion is insufficient, the strength is very good in the short term after repairing with this material, but it is easy to crack and delaminate in the later stage, so the unit of this material is relatively small.

1.Repair of thin surface layers (hemp surface, exposed aggregates, etc.).

The surface can be cleaned to expose the solid concrete part, and then the surface can be scraped with JN-X concrete repair adhesive or JN-F sealing adhesive. In order to ensure a better repair effect and aesthetics, the edge of the repair area should be cut into the old concrete about 10mm and cut into a regular shape. The color of JN glue after repair is close to the natural color of concrete, if there are higher requirements for color, an appropriate amount of pigment can be added on site.

2.Partial repair of potholes (joints and corners).

JN-X concrete repair adhesive using organic epoxy resin as cementing material is used for local rapid repair of concrete pavement potholes (joints and corners). JN-X concrete repair adhesive is a two-component modified epoxy resin adhesive with A and B, which is composed of a variety of organic and inorganic modified materials, and its main characteristics are:

1) Curing at room temperature, the curing speed is fast, and it can be adjusted according to user requirements;

2) High strength and bonding strength with concrete;

3) It does not contain volatile solvents, and basically does not shrink during hardening;

4) close to the color of concrete;

5) Good anti-aging and medium resistance (acid, alkali and water, etc.);

6) The ratio of the two groups of dispensing glue is wide, which is convenient for on-site operation;

7) It can be operated for a long time, easy to use and non-toxic.

Concrete repair material is a good Guheng concrete quick repair treasure is a super repair concrete repair material, its material performance has been recognized by the traffic department and road maintenance units in many regions, the main reasons are the following three points:

The material has high adhesion and compressive strength

Guheng concrete fast repair treasure after 3 times of relatively large material formula upgrade, at present, its material adhesion and compressive strength in the industry has been the top, with Guheng concrete fast repair treasure repair after the cement pavement repair of about 100 tons of heavy truck rolling will not appear any cracking, delamination, from the service life, as long as the pavement foundation is firm, generally can be used for 5-8 years.

The material is cost-effective

The concrete repair materials on the market are generally 25kg packaging, and Guheng Concrete Quick Repair Bao is 40kg packaging, however, 1 bag of Guheng Concrete Quick Repair Bao can add 60kg of sand and mix it into 100kg of finished concrete repair materials, after many real-world tests, under the premise of the same repair effect, 58% of the repair cost can be saved with Guheng Concrete Quick Repair Treasure.

Professional pre-sale, in-sale and after-sales service

After investigation, it was found that more than 70% of the cement pavement was caused by the wrong judgment of the cement pavement before the pavement repair, resulting in the wrong pavement repair plan, Guheng has 8 years of experience in concrete repair, and can provide users with targeted concrete repair solutions with rich experience.

At the same time, according to the needs of users, Guheng provides customers with different formulas of repair materials, so the cement pavement repaired by Guheng Concrete Quick Repair Treasure is very durable.

A similar product is a high-sized cement glue that copes with inspection and acceptance. Due to the substandard construction at that time, laying 3-5 mm to change the product, can only cope with it. The tofu is crusty, and if you want the tofu not to break, it's impossible to think about it.

It can only be a hard crust on the tofu, put it there and don't move, and hand it over after inspection, and it doesn't matter after three years.

Glad to serve you :

There are many concrete pavement repair materials, I am a maintenance worker, I use Jiage Weiye joint filling glue, which has strong adhesion, will seal the cracks tightly, and will not be taken away by the wheels.

1. Concrete repair agent, a more common repair material, is more beautiful after use for pavement sanding, potholes and other diseases, and there is no color difference.

2. The rush repair mortar is used for repairing wide cracks in concrete pavement.

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.

The combination of new and old concrete is the weak link, and one of the important factors causing the poor combination of new and old concrete is the shrinkage of new concrete. The shrinkage stress generated by the collection makes the new and old concrete pull apart; Therefore, the cut joints after repair should be tightly closed and not shrink to prevent the freezing damage of the road surface caused by rain and ice and snow.

You can pay attention to the product of Repair King!

There are many types of concrete pavement repair materials, and from the comprehensive point of view of repair effect and repair cost, Guheng concrete quick repair treasure is more worthy of choice. In Liaoning, most of the frozen cement pavement is repaired with this material.

Summary. 1. If the sand formation or hollowing phenomenon of the cement floor is not particularly serious, you can choose a professional cement floor sand treatment agent, which is a water-soluble chemical ingredient that can effectively penetrate into the cement floor and react with the ground.

2. When processing, the cement floor should be cleaned first and rinsed with water in advance.

3. Next, the liquefied gas on the cement floor should be completely dry, so that the sand or hollowing phenomenon of the cement floor can be changed to avoid the problem of cracking again in the later stage.

4. If the problem of damage to the cement floor is serious, clean the ground first, then add the treatment agent to water to dilute it, and evenly apply it to the repaired place. Generally speaking, it is necessary to brush twice before and after, brush the second time after each drying, and then add high-strength cement to mix putty powder to repair the base layer, which can effectively improve the problem of cement floor.

This is my answer, I hope it is helpful to you, thank you <>

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:

1. Simple and fast.

Good working performance and simple construction technology. There is no need to do too much treatment for the diseased parts of the original pavement, both manual and mechanical can be used, and the scattered diseased parts can be repaired at any time; Appropriate setting time. It can be opened to traffic 24 hours after construction, and it can be faster if there are special requirements, without the need for a long time to close traffic.

2. Ultra-thin repair.

It has good bonding strength with the old concrete, and the thinnest can be 3mm without falling off and not chipping, especially for the diseased parts of the hemp surface and peeling, and can be repaired with ultra-thin under the premise of not raising the foundation height of the road surface to prevent the disease from expanding.

3. Neat and beautiful.

It has good compatibility with the old concrete, close to the color of the original cement concrete pavement, and the color of the material can be adjusted according to the color of the original pavement to achieve better color compatibility, and there is a better aesthetic degree after repair.

4. Strong and durable.

Faster hardening speed and higher early strength, while the later strength does not attenuate, but continues to rise, and can be one-time for many disease parts; The linear expansion coefficient is close to that of the original pavement concrete, and when the cement concrete expands and contracts, the repair material will not be pulled off.

5. Strong adaptability.

It has strong water stability and frost stability, and can not change the performance in the environment of -60 -+60, which is suitable for use in areas with various climatic conditions, hydrological conditions and construction conditions.

6. Cost-effective.

Because the repair of many pavements is permanent, the construction is convenient, and there is no need to excavate, which saves a lot of construction costs and material costs, eliminates and delays the spread and spread of road diseases, and prolongs the service life of roads.
