Main Functions:
The tensile strength and flexural strength of concrete can be increased by 20%-50% and 40%-80% when appropriate steel fiber is added to concrete. Under the usual fiber dosage, impact compression toughness can be increased by 2-7 times, impact shear, tensile toughness can be increased by several times to dozens of times. Because of the crack resistance and integrity of steel fiber concrete, the freeze-thaw resistance, heat resistance, wear resistance, cavitation resistance and corrosion resistance have been significantly improved. Concrete collective itself is a kind of multi-phase, multi-component, non-uniform granular brittle composite material, its compressive ratio is only about one tenth, crack resistance is very low.The addition of steel fiber prevents the initiation of cracks and reduces the size and number of cracks. In the process of loading, the extension and expansion of cracks are inhibited, and the stress and concentration of cracks are alleviated.
