What can fiber in the fiber concrete do? 1, Improve the toughness of concrete; 2, Improve the flexural capacity of concrete; 3, Effective control of concrete cracking; 4, Appropriately increase the compressive strength of concrete; 5, Improve the impact resistance of concrete
The composite can continue withstand high load and large deformation, especially in its large toughness until fiber is selected from base material. Compared with ordinary concrete, it can be used to limit the expansion of cracks in the concrete base under the action of external forces. The tensile ultimate strength can be increased by 30 ~ 50%. The fiber reinforced concrete mainly uses short fiber which has a certain length to diameter ratio (i.e., the ratio of the length to the diameter of the fiber). In the design and use of fiber concrete, please refer to the current "technical specification for fiber reinforced concrete structure" if the volume content of the fiber is greater than a critical value, when the ingredients are suitable and suitable for high efficiency water reducing agent. The main function of fiber in fiber concrete. The fiber is the acceptance of the main external force. The fiber products (such as glass fiber mesh cloth, fiber reinforced concrete has high tensile strength and ultimate bending strength., cement-based material and fiber to bear when the external base material occurred after cracking, initial bending). But sometimes we often use long fiber (such as glass fiber roving.
