RPC concrete fiber micro steel fiber with copper coated hooked end steel fiber

C opper coated micro steel fiber is a special kind of metal fiber, which has strong compressive, tensile and crack resistance. It is widely used in high-speed iron prefabrication, RPC cover plate, exterior wall painting and important engineering components. It can improve the tensile strength, compressive strength, shear strength, impermeability, impact resistance and fatigue strength of concrete.

The main function of steel fiber distributed randomly in SFRC is to block the expansion of micro cracks in concrete and the occurrence and development of macro cracks. In the initial stage of loading (tension and bending), cement-based materials and fibers bear the external force together. When the concrete cracks, the fibers across the cracks become the main bearers of the external force. Therefore, compared with ordinary concrete, SFRC has a series of superior physical and mechanical properties.

1. High tensile, bending, shear and torsional strength

2. Good impact resistance

3. Obvious improvement in shrinkage

4. Significantly improved fatigue resistance

5. Significantly improved durability

Advantage of steel fiber reinforced concrete

1. Under the same strength, the amount of concrete can be reduced by 30% ~ 50%;

2. It can replace or partially replace the reinforcement or reduce the reinforcement diameter by 1-2mm;

3. It can shorten the construction period by more than 25%, especially for large projects requiring continuous and rapid concrete pouring;

4. Mixing construction is the same as ordinary concrete, no need to add equipment
