Precautions for using high-strength road repair materials in highway pavement repair
What is the typical model of non shrink cement grouting material for Jinxiang structural reinforcement grouting
The development of building sealants, structural sealants, and bonding materials is rapid, and there are also relevant standards and regulations, mainly applicable to building doors, windows, glass curtain walls, and ceramic bonding. Natural stone, with its unique characteristics and architectural requirements, is not suitable for all adhesives. In foreign countries, it is selected based on relevant standards and a large number of experiments on the basis of design. Based on technical discussions and exchanges with relevant foreign institutions, Europe and the United States have referred to the content of EN124.21 "Ceramic Tile Adhesive" in the wet pasting of stone, and made local adjustments according to the characteristics of stone. The national industry standards for stone dry hanging adhesives and stone sealants that have been introduced in our country are far from sufficient due to their limited scope of application, and cannot meet the actual needs and safety guarantees of various adhesives for stone.
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.

Compared with the traditional GRC lightweight wallboard, the use of foam concrete production technology can not only significantly reduce the cost of the product, but also greatly improve the fluidity of the slurry, making molding more convenient. The physical and mechanical properties of this product are shown in Table 3. Modern architectural design and construction of foam concrete compensation foundation pay more and more attention to the free settlement of buildings during construction. Due to the different self weights of various parts of the building complex, there will be free settlement differences during the construction process. In the design process of the building, it is required to fill soft materials in the foundation of the parts with lower self weight as compensation for the foundation. Foam concrete can better meet the requirements of compensation foundation materials.
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.
Flash point: For solvent based products, the flash point must be determined according to ASTM D39. This is the most basic method to determine whether a product is flammable or explosive. PH measurement: At room temperature, use a pH meter to measure the pH value of the cleaning solution and its concentration (up to. 1PH), and mark it. Stability: Stability mainly depends on the high or low temperature stability of the cleaning agent: Pour the liquid cleaning agent into a clean 6ml glass reagent bottle, place it in a 4 ± 1 ℃ oven or a 3-to-1~(2) refrigerator, take it out after 24 hours, and let it return to room temperature indoors. Check its appearance and odor, which should be basically unchanged compared to before the measurement.

There are various problems with stone, which will be solved with the introduction of crystal plating double anti modifier for stone. The crystal plating double anti modifier is composed of various inorganic nanomaterials and water, and is used to treat the surface of the stone. Under the heat generated by polishing, the water evaporates while the components undergo chemical reactions and form a firmly attached crystal glaze coating (with a chemical composition similar to granite). The crystal glaze coating has the following characteristics: anti slip performance, and the friction coefficient of the crystal glaze coating reaches. 88 on the granite surface and. 8 on the marble surface, both reaching or exceeding the very safe friction coefficient of. 8.
