    To ensure that the ultra-flat floor achieved after laser leveling and polishing construction can maintain its flatness for a long time, the selection of foundation materials is the first crucial step that determines success or failure. The core logic of material selection lies in: controlling volume stability (reducing shrinkage and deformation) and ensuring uniformity of construction (providing an ideal medium for mechanical construction). The following are the key material selection points summarized based on engineering practice and technical specifications: The design of the concrete mix ratio directly determines the shrinkage rate and crack resistance of the hardened floor, which is the fundamental factor for long-term flatness. Material category Key indicators / recommended requirements The mechanism of the long-term flatness effect Cement Ordinary Portland cement; in the same area and of the same batch number It reduces the surface color difference and internal stress unevenness caused by the chemical shrinkage difference of cement, and lowers the risk of warping. Water-cement ratio ≤0.48 Strictly controlling the water-cement ratio is the fundamental means to reduce the dry shrinkage rate of concrete. The larger the water-cement ratio, the more severe the shrinkage, and the more likely it is to crack and deform in the later stage. Slump For pumping: 100-140mm Provide stable operation for the laser leveling machine. If the slump fluctuates too much, it will make it difficult for the machine to level properly, resulting in local height errors. For non-pumping: 30-35mm Aggregate Sand: Grade II grading, strictly control the clay content A good gradation forms a stable framework structure, reducing the amount of cement paste and thereby lowering shrinkage. High clay content can damage the adhesion between cement and aggregates, causing cracks. Gravel: Continuous grading, maximum particle size ≤ 2/3 of the plate thickness The maximum particle size of the aggregate Recommendation: ≤25mm Excessive particle size will be lifted by the machine during the leveling and polishing processes, thereby damaging the surface flatness and appearance. For high-standard ultra-flat floors, ordinary concrete alone is often insufficient. Functional materials need to be introduced to enhance the overall performance. Steel fibers Concentration reference: 15kg/m³ (determined based on design load) Significantly enhances the tensile and flexural strength of concrete, effectively prevents the expansion of micro-cracks, and prevents plate warping. Compared to steel mesh, steel fiber concrete is more suitable for continuous operation by laser leveling machines, with higher efficiency. Synthetic fibers Macroscopic polypropylene fibers, etc. Mainly controls early plastic shrinkage cracks, reduces surface micro-cracks caused by excessive early water loss, laying a foundation for later flatness. Wear-resistant aggregate Metal or non-metallic aggregates (such as diamond powder, aluminum oxide, etc.) Sprayed on the concrete surface, after being compacted by a trowel, it forms a high-density, high-maintenance surface layer. This "armor" can resist wear and uneven settlement caused by long-term rolling by forklifts. Sealing curing agent Lithium-based or sodium-based liquid hardeners Penetrates into the concrete interior, reacts with calcium hydroxide to form hard calcium silicate, permanently sealing the capillary pores. It can greatly enhance surface hardness, density and impact resistance, preventing damage to flatness caused by later dusting and sanding. If the foundation is unstable, the floor will deteriorate. All the selection of upper materials is based on a stable foundation. Foundation treatment: It is necessary to ensure that the compaction degree meets the design requirements (such as the ground endurance K value is greater than 0.06 N/mm³). Uneven settlement is the fatal flaw that leads to floor cracking and loss of flatness. Base layer design: Usually, a C15 concrete base layer is set up, and a PE moisture-proof membrane is laid to block the upward movement of capillary water and prevent interlayer separation or expansion deformation caused by water vapor. Reinforced mesh (if applicable): For non-steel fiber concrete, the reinforced mesh needs to be configured according to the design to control shrinkage. However, it should be noted that the construction efficiency of the reinforced mesh is lower than that of steel fibers. To achieve long-term flatness of the super-level flooring, the selection of materials should follow the principle of "combining hardness and softness, and advancing steadily while maintaining stability": The foundation must be stable: Use concrete with a low water-cement ratio and high-quality graded aggregates as the base to ensure volume stability. The framework must be strong: Enhance the crack resistance by using steel fibers or steel mesh sheets to counteract shrinkage stress. The surface layer must be resilient: Create a high-strength and durable surface with wear-resistant aggregates and seal curing agents to resist usage wear.   What is the specific grade requirement for the flooring flatness in your project (for example, does it need to meet free passage or VNA narrow aisle shelving)? This directly relates to whether steel fiber concrete is needed and the amount of wear-resistant aggregates.

Frequency of cleaning and maintenance of emery floor 1. Characteristics of emery floor Emery floor, as the common name for wear-resistant hardened floor in China, has quickly occupied an important position in the field of floor decoration such as industrial sites, docks, parking lots, commercial stores, and logistics warehouses with its excellent wear resistance, compression resistance, and impact resistance since it was introduced by foreign companies in the 1990s. This floor has various colors, including cement color, gray, green, yellow, red, etc. The surface is dense and not easy to dust, and it is easy to clean. Compared with traditional industrial floor terrazzo, emery floor not only has higher cost performance and service life, but also greatly simplifies the construction process. It can be constructed simultaneously with concrete, saving a lot of time and labor. However, the microstructure of emery floor shows that its surface is relatively rough, and there is a capillary structure of concrete, which makes the floor not resistant to penetration, pollution, and corrosion of substances such as acid, alkali, and oil. Therefore, in daily use, the cleaning and maintenance of emery floor is particularly important. 2. Factors affecting the use environment The use environment is a key factor affecting the frequency of cleaning and maintenance of emery floor. Emery floors are usually faced with a variety of harsh environmental challenges, such as the operation of heavy machinery, the splashing of chemicals, and the penetration of water. These factors will directly affect the life and performance of the floor. For example, the operation of heavy machinery will cause frequent impact and friction on the floor, accelerating the wear of the floor; the splashing of chemicals may cause corrosion and discoloration of the floor surface; and the long-term penetration of water may cause cracking and dusting of the floor. In addition, the way of use will also have an important impact on the frequency of cleaning and maintenance of the floor. If heavy objects are often placed on the floor or a large number of objects are operated, the pressure and load on the ground will increase, thereby accelerating the wear and aging of the floor. 3. Cleaning and maintenance cycle recommendations Considering the characteristics of emery floors and the influence of the use environment, we recommend regular cleaning and maintenance of emery floors. The specific frequency can be adjusted according to actual conditions, but it is generally recommended to clean the floor at least once a week. During the cleaning process, the garbage and debris on the ground should be cleaned up first, and then professional cleaning agents and tools should be used for deep cleaning. In addition, for oil stains or other difficult-to-remove stains, specific cleaning agents or tools may be required for treatment. At the same time, we also recommend regular maintenance and care for the Jinze sand floor. This includes checking the integrity of the floor, promptly discovering and dealing with possible cracks or damage: regularly waxing or applying protective agents to the floor surface to improve its wear resistance and corrosion resistance; and ensuring that the use environment is dry and clean to avoid excessive moisture and chemicals from damaging the floor. 4. Professional cleaning and maintenance process The professional diamond sand floor cleaning and maintenance process usually includes the following steps: first, conduct a comprehensive inspection of the floor and record the areas and problems that need special attention; second, use professional cleaners and tools to deep clean the floor to remove stains and grease; then, make necessary repairs and treatments to the floor surface, such as filling cracks and polishing uneven areas; finally, wax or apply protective agents to the floor as needed to enhance durability and beauty. During the cleaning and maintenance process, standard cleaners and tools should be used to avoid using chemicals or sharp tools that damage the floor. At the same time, the professional skills and operating specifications of the cleaning and maintenance personnel should be ensured to avoid unnecessary damage to the floor. 5. Selection of maintenance materials and equipment When choosing maintenance materials and equipment, attention should be paid to their quality and performance. For cleaning agents, products that are harmless to the diamond floor and have good cleaning effects should be selected; for waxing or coating protective agents, wear-resistant, corrosion-resistant and environmentally friendly products should be selected. In terms of equipment, cleaning and maintenance equipment with stable performance and easy operation should be selected, such as high-pressure cleaning machines, vacuum cleaners, polishing machines, etc. These equipment can not only improve the efficiency and quality of cleaning and maintenance, but also reduce damage to the floor. 6. Daily maintenance and precautions In addition to regular cleaning and maintenance, daily maintenance of diamond floors is equally important. First, the use environment should be kept dry and clean to avoid excessive moisture and chemicals from damaging the floor. Secondly, people and items entering the floor should be properly managed and controlled to avoid scratches or impacts on the floor caused by sharp or heavy objects. In addition, the integrity of the floor should be checked regularly to detect and deal with possible problems in a timely manner. During use, the following points should also be noted: First, avoid scratching the floor surface with hard objects; second, avoid direct contact of strong acids, alkalis and other chemicals on the floor surface; third, regularly clean and maintain to keep the floor clean and beautiful. 7. Common problems and solutions In the process of using diamond sand floor, you may encounter some problems, such as reflection, noise and cracking. For these problems, we can adopt some effective solutions. For example, for reflection problems, it can be handled by grinding, waxing or spraying; for noise problems, sound insulation materials or processes can be used to improve; for cracking problems, it is necessary to pay attention to basic treatment and material selection during construction and maintenance to ensure the integrity and stability of the floor. In addition, stains or scratches that occur during use should be handled and repaired in time. For stains, professional cleaning agents can be used to remove them; for scratches, local repairs or overall renovations can be performed according to the depth and area of ​​the scratches. 8. Summary and long-term planning In summary, the cleaning and maintenance of diamond sand floor is the key to ensuring its long-term performance and aesthetics. Through regular cleaning and daily maintenance, the service life of the floor can be effectively extended and the maintenance cost can be reduced. At the same time, choosing appropriate maintenance materials and equipment and standardized operating procedures are also important factors to ensure the cleaning and maintenance effect. In the future, with the advancement of science and technology and the improvement of environmental protection requirements, the cleaning and maintenance technology of diamond sand floor will also be continuously updated and improved. From a long-term perspective, for the maintenance and management of diamond sand floor, we also need to consider the following points: First, strengthen the training and management of floor users. Through training and publicity, improve the awareness and attention of users to floor protection, and avoid floor damage caused by human factors. Secondly, establish a complete cleaning and maintenance file. Record the time, content, effect, etc. of each cleaning and maintenance, so as to track and analyze the use of the floor, and find and solve problems in time. In addition, pay attention to industry development trends and technological innovation. With the continuous development of the floor industry, new materials, processes and technologies continue to emerge. We should maintain a keen insight, timely understand and master new technologies and methods to improve the cleaning and maintenance effect and service life of the floor. Finally, strengthen the environmental protection management of the floor. When choosing cleaning and maintenance materials and equipment, attention should be paid to their environmental performance and reducing pollution to the environment. At the same time, discarded cleaning and maintenance materials and equipment should be properly handled to avoid adverse effects on the environment. In short, the cleaning and maintenance of diamond sand floor is a long-term and important task, which requires us to invest sufficient time and energy in management and maintenance. Through scientific cleaning and maintenance methods and standardized operating procedures, we can ensure the long-term performance and aesthetics of the floor, and provide strong support for the production and operation of the enterprise. In actual operation, we also need to flexibly adjust the frequency and methods of cleaning and maintenance according to the specific use environment and floor conditions. For example, in areas with heavy oil pollution, it may be necessary to increase the frequency of cleaning or use stronger detergents; in areas with dense traffic, it may be necessary to strengthen daily maintenance and maintenance work. In addition, for some special cases, such as large-scale wear or severe pollution of the floor, we need to take professional repair and renovation measures in time. This may require the help of a professional floor repair team and advanced repair technology to ensure that the integrity and aesthetics of the floor are restored. In future development, with the application of intelligent and automated technologies, the cleaning and maintenance of diamond sand floor is expected to achieve higher efficiency and lower costs. For example, by introducing intelligent cleaning robots and automated maintenance systems, we can achieve regular and fixed-point cleaning and maintenance of the floor, reducing the tediousness and errors of manual operations. In short, the cleaning and maintenance of diamond sand floor is a comprehensive task that requires us to consider and implement from multiple aspects. Through scientific management and maintenance measures, we can ensure the long-term performance and aesthetics of the floor, and provide strong guarantees for the sustainable development of the enterprise.
