The aspect ratio of steel fiber (the ratio of steel fiber length L to diameter D, and the method of producing steel fiber) can strengthen concrete. The reinforcement effect of steel fiber mainly depends on the matrix strength (FM. I / D, fiber volume fraction, bond strength between fiber and matrix (τ), and fiber distribution and orientation (η) in the matrix. When the steel fiber is damaged, most of the fiber is pulled out rather than broken, so improving the bond strength between the fiber and the matrix is one of the main control factors to improve the fiber reinforcement effect. Environmental protection technology in developed countries is developing in depth and cutting-edge, and products are developing in the direction of popularization, standardization, complete set and serialization. At present, new material technology, new energy technology and bioengineering technology are introduced into environmental protection industry from time to time. The characteristics of the development of environmental protection industry, the rapid penetration of high-tech into the environmental protection industry; green products and clean production become the trend of the times. Recently, it has attracted a lot of customers' attention. The steel fiber has many excellent properties, such as high modulus and axial strength, low density, high specific properties, no creep, ultra-high temperature resistance, good fatigue resistance, specific heat and conductivity between non-metallic and metal, small thermal expansion coefficient and anisotropy, good corrosion resistance and good X-ray transmission. Good electrical and thermal conductivity, good electromagnetic shielding, etc.
Attract a lot of customers' attention. The product developed this time, a kind of steel fiber appeared in the environmental protection building materials industry. The new product developed by the R & D team with painstaking efforts is also a breakthrough in domestic fiber technology. It is of great significance to expand domestic fiber market share and further develop overseas fiber market. Steel fiber has many excellent properties, such as high modulus and axial strength, low density, high specific properties, no creep, ultra-high temperature resistance, good fatigue resistance, specific heat and conductivity between non-metallic and metal, small thermal expansion coefficient and anisotropy, good corrosion resistance and good X-ray transmission. Good electrical and thermal conductivity, good electromagnetic shielding, etc. Compared with traditional products, steel fiber is insoluble in organic solvent, acid and alkali, and has outstanding corrosion resistance. "Stronger, more durable, more safe" product steel fiber as a new type of composite material with excellent performance is out of people's eyes, but the construction industry is acclaimed. The steel fiber can greatly reduce the stress convergence at the end of the crack caused by the load in the matrix, so as to control the expansion of the concrete gap from time to time. With the rapid development of China's Construction Engineering, people's requirements for the project are higher and higher, so the steel fiber as a new type of building materials stands out in the construction engineering. For further development in the future, domestic enterprises should appropriately accept the advanced enterprise skill level, introduce advanced skills, set up equipment arrangement, cultivate practical talents, etc. Now, due to the large demand of the construction market, steel fiber products are very popular, and the steel fiber is also hot selling. Users can choose their own steel fiber according to their own market demand.
