This effect is different from general reinforcement, but rather a fundamental improvement of the inherent defects of concrete/mortar. This includes effectively increasing the toughness of concrete; Reduce cracks and improve impermeability; Reduce cracks and delay steel corrosion; Reduce chemical erosion on concrete structures; Enhance frost resistance and reduce damage to concrete structures; Reduce the bleeding of concrete and improve the quality of surface concrete; Reduce cracks, improve wear resistance and impact resistance, etc. The role played is not something that can be reflected by a few strength indicators, but a comprehensive reflection of multiple indicators, especially the durability of concrete. The true significance of synthetic fiber reinforced concrete becoming a hot topic in the domestic theoretical community lies in how to truly reveal and measure the essence of the effect of fibers on concrete.

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.

At present, there are several common problems in engineering applications, such as the lack of technology research and development, the integration of different materials, and the formation of different technologies. This is well known. At present, except for a few enterprises, most of the external wall insulation technology production enterprises in China are still in the stage of imitating technology due to the lack of independent research and development capabilities. There is little research on the basic theory, structural measures, principles, and system formation mechanisms of technology; Once alternative materials are sought due to low price competition, there will be a decline in system performance and the quality of the project cannot be guaranteed. The simple improvement of industrial kiln and pipeline insulation technology for building energy conservation cannot provide excellent insulation performance due to the different insulation mechanisms of the system and changes in the usage environment. The system is in a non dry state at room temperature and humidity for a long time.

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.

Stone is mainly used in the field of architectural decoration. Compared with other decorative materials, the characteristic of stone is that it belongs to natural minerals, and its unique decoration lies in many aspects such as color, texture, lines, and hardness. In addition to the type and color of the stone, the price, quality, and durability of the stone are also major considerations: Price: Stone is a natural mineral. Due to differences in quality, quantity, mining area, and processing technology, there will be significant differences in the prices of different grades of stone. This requires homeowners and designers to choose suitable stone materials based on the project budget. To achieve this, you should have a considerable understanding of the price of stones. Nowadays, most stone consumers have gone astray: high priced stone is good stone, or imported stone is better than domestic stone.

Rubber foam insulation material is a soft and energy-saving insulation material made by using high-performance rubber/polyvinyl chloride (NBR/PVC) as the main material, and introducing technology and fully automatic continuous production lines. It is foamed through complex processes. Rubber foam insulation material is suitable for insulation of various cold and hot medium pipelines and containers. Key points for construction and installation of rubber foam insulation materials: The insulation engineering construction of air ducts, components, and air conditioning equipment should be carried out after the tightness inspection of the air duct system is qualified. The construction of refrigeration system pipelines in air conditioning engineering, including refrigerant and air conditioning water system insulation engineering, should be carried out after the strength and tightness inspection of the pipeline system and the completion of anti-corrosion treatment.
