Precautions for using high-strength road repair materials in highway pavement repair

What is the typical model of CGM high-strength non shrink grout for Haiyang bearings

Due to the diverse reasons for the formation of dirt on the surface of stone, the principles and methods of use of corresponding cleaning agents are inevitably different. Stone cleaning agents must be labeled with categories, especially the objects and conditions of cleaning, as well as detailed usage methods. It is obvious that stone cleaning agents are not like protective agents, and it is difficult and unnecessary to unify all technical requirements. Different cleaning agents can be tested for their basic performance and stain removal ability based on their own characteristics. Basic performance testing is to ensure that it is harmless to stone, the environment, and the environment, while stain removal ability testing is to determine the cleaning effect of the cleaning agent. The basic performance of stone cleaning agents includes physical and chemical properties.

When high-strength road repair materials are applied to road surface repair, a lot of things need to be mixed in order to achieve strength. Although high-strength road repair materials have high strength, they are relatively brittle overall. In this case, it is recommended to add steel fiber high-strength road repair materials during the mixing process, which can produce buffering under huge pressure.  

Secondly, it is necessary to choose high-strength road repair materials that solidify quickly and reach strength within 2 hours, because during road repair, it is necessary to open to traffic in a short period of time.

Then, when selecting steel fibers, it is important to pay attention to the proportion of addition, which depends on different situations, such as high-strength road repair materials and steel

Please refer to the guidance of technical personnel from the grouting material manufacturer for the proportion of fibers.

When the external temperature exceeds the normal range too much, the foaming agent will overflow prematurely when it reaches the boiling point, and the prefabricated foaming material will become ineffective or ineffective. Dynamically adjusting the ambient temperature for material storage through the car's trunk will become an effective solution. Short term pipelines without heating devices will inevitably make it difficult to transport large amounts of materials upstairs, with high handling intensity and inability to adjust the temperature of the bucket materials, which will lose the advantage of mechanized and fast construction. The four essential components required for on-site spraying of exterior wall insulation systems are a high flow high-pressure airless pressure supply system, a high atomization spray gun, an ultra long heating pipeline, and a vehicle mounted temperature control box, all of which are indispensable. The second is the combination selection of raw materials for on-site spraying. Spray type rigid foam for thermal insulation requires not only high reactivity polyether polyols and poly (P: PI) combinations, but also the following factors to be considered according to the process and application.

Steel fibers need to be added during the mixing process to ensure even mixing.

Cleaning the road surface:

1. The road surface needs to be cleaned thoroughly and there should be no debris

2. Need to carve out a certain height for grouting

3. Need maintenance, watering and moisturizing the road surface

4. After the road repair, it will be open to traffic in about 2 hours.

The gelatinized honeycomb used as a wall material has a capacity of 4 cubic meters per ton and can replace over 20000 standard bricks by volume, equivalent to 80000 standard bricks in terms of sound insulation and thermal insulation performance. Adhesive honeycomb composite materials can replace bricks with paper, wood with paper, metal with paper, and cement with paper. Using gelatinized honeycomb composite materials as walls instead of traditional walls can save the weight of traditional walls (about 8%~9%), greatly reduce the burden on the main components and foundation, and make the main components lighter and less burdensome on the foundation. This gelatinized honeycomb composite material wall can also save expenses, reduce building costs, and more importantly, save valuable resources and protect the environment.

Focusing on building a modern construction industry, Gu Zhen'an pointed out that in order to develop a circular economy in the construction industry in Shenzhen, the city's construction industry is very developed. Therefore, in order to develop a circular economy in Shenzhen, it is necessary to promote the coordinated development of green building industry and building materials industry. Gu Zhen'an pointed out that with the deepening of the concept of green buildings, conserving resources, energy, and developing eco-friendly buildings have become the development trend of the future construction industry. Green buildings must develop multifunctional composite wall materials, energy-saving flooring and doors and windows, insulation roof materials and other building components. In addition, the construction industry should be called upon to improve the durability of buildings. If the design and service life of buildings in China can be increased from the current 5-6 years to 9-1 years, it will play an important role in slowing down the rapidly growing demand for building materials and reducing resource, energy, and environmental loads, promoting the coordinated development of green buildings and building materials industry.
