What materials need to be used for the repair of concrete pavement

The finished concrete pavement special repair agent, Lumei perfect series repair material has high strength and wear resistance, super bonding, rapid curing, easy operation, durability and crack resistance, compression and anti-slip, spalling and corrosion resistance.

1.Partial repair of potholes:

The local rapid repair of concrete pavement potholes adopts concrete repair adhesive with organic epoxy resin as the cementing material. 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) Good anti-aging and medium resistance (acid, alkali and water, etc.);

2) High strength and bonding strength with concrete;

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

4) close to the color of concrete;

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

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.

2.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 coated with concrete repair glue or sealing glue. 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.

Vantone's concrete high-strength repair material is a new type of concrete repair material that has both the adhesion of polymer materials and the durability of inorganic materials. High compressive strength, rapid curing, good bonding performance; It has good water retention and crack resistance, high alkali resistance, and ultraviolet resistance; It is easy to operate, can be constructed with wet base layer, and is healthy and environmentally friendly. It makes the construction steps simple and convenient, and the durability is synchronized with the concrete, shortening the construction period and ensuring economy.

The formula of cement pavement rapid repair material is generally made of cement, sand, additives, etc., and the specific formula ratio varies according to different specific conditions, which can be roughly divided into the following types: 1Cement mortar formula:

Cement: Sand: Additives=.

2.Cement asphalt mixture formula: cement:

Sand: additive =, while adding 20% of asphalt. 3.

Asphalt mortar formulation: asphalt: sand:

Additives = Cement Modified Asphalt Mortar Formulation: Asphalt: Cement:

Sand: additive =, add rubber or other materials for modification. The above are common quick repair formulas, and other composite materials can also be used to repair potholes and cracks on the road surface.

For example, concrete glue mortar formulation: cement: sand:

Polymer Notebook Rubber Powder: Trouble-destroying Additive =; Cement mortar surface layer formula: cement:

Sand: Additives: Polymer Gelling Agent = ; Asphalt mortar surface course formula:

Asphalt: Sand: Additives:

Polymer gelling agent = . When preparing the repair material, some other factors should also be considered, such as the selection of protective measures when using concrete; The use of asphalt mortar should minimize the crosslinker content to reduce pollution. In addition, when the cement mortar is prepared for the repair material liquid with high impact, the appropriate fineness should be selected according to the road surface conditions to avoid bending, cracks and other phenomena.

Summary. The formulation of pro-cement pavement rapid repair materials can include the following ingredients:1

Cement: As the main curing agent, it can quickly form a strong hardened layer on the road surface. 2.

Sand: Used to adjust the particle size of the material and increase the strength of the material. 3.

Lime: It can improve the plasticity of the material, reduce the dry shrinkage rate of cement, and prevent cracking. 4.

Water: Used to regulate the viscosity and fluidity of the material.

The formulation of pro-cement pavement rapid repair materials can include the following ingredients:1Cement:

As the main curing agent, it can quickly form a strong hardened layer on the road surface. 2.Sand:

It is used to adjust the particle size of the residual material and increase the strength of the material. 3.Lime:

It can improve the plasticity of the material, reduce the dry shrinkage rate of cement, and prevent cracking. 4.Water:

It is used to adjust the viscosity and vertical flow of materials.

Depending on the situation, it can be prepared in the following proportions: - Cement: 4 parts - Sand:

5 parts - Lime: Parts Yuwei - Water: 2 parts Mix the above ingredients and stir well to ensure that there is no clumping before use.

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.

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.

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.

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.
