INTRODUCTION AND USAGE

Copper-plated micro-filament steel fiber is mainly used for high-speed railway, RPC cover plate and important engineering components. It has high tensile strength, wear resistance, crack resistance, bending resistance, bending resistance, impact resistance and other properties.

Copper-plated microfilament steel fiber is a special kind of metal fiber, which has strong compressive, tensile and crack resistance properties and is widely used in high-iron prefabricated parts, RPC covers, exterior wall paintings, and important engineering components. Can greatly improve the concrete’s tensile strength, compressive strength, shear strength, impermeability and increase concrete impact resistance, improve fatigue resistance and other important performance.

The main role of the steel fibers distributed in the steel fiber reinforced concrete in random directions is to hinder the expansion of micro cracks in the concrete and block the occurrence and development of macro cracks. In the initial period of loading (pulling, bending), the cement base material and the fiber are subjected to external forces together. When the concrete cracks, the fiber that crosses the crack becomes the main bearer of the external force. Donc, steel fiber reinforced concrete has a series of superior physical and mechanical properties compared with ordinary concrete.

SPECIFICATION

Physical and mechanical properties of steel fiber reinforced concrete

1. High tensile, flexural, shear and torsional strength

Incorporation of appropriate amount of steel fiber in concrete, its compressive strength increased by 10% à 80% (C50 and above concrete increased significantly), tensile strength increased by 50% à 100%, bending strength increased by 50% à 80%, shear Strength increased by 50% à 100%. Tests have shown that ultra-short steel fibers with a length of 5 à 15 mm and an aspect ratio of 10 à 30 have a much smaller increase in compressive strength, but much lower tensile strength and flexural strength.

2. Excellent impact resistance

The performance of the material to resist impact or vibration load is called impact toughness. Under the general fiber content of “Just/T&C Fiber Reinforced Concrete Steel Fiber” JT/T, the impact compressive toughness can be increased by 2 à 7 fois, impact bending resistance, Tensile strength such as tensile can be increased several times to tens of times.

3. Significantly improved contraction performance

With the usual fiber content, the shrinkage value of SFRC is lower by 7%~9% than that of ordinary concrete.

4. Significantly improved fatigue resistance

The resistance to bending and compressive fatigue of steel fiber reinforced concrete is greatly improved compared with ordinary concrete.

5. Durability can be significantly improved

Due to the good crack resistance and integrity of steel fiber concrete, freeze-thaw resistance, heat resistance, wear resistance, cavitation resistance, and corrosion resistance are all significantly higher.

STEEL FIBER CONCRETE COMPARED WITH ORDINARY CONCRETE

Steel fiber reinforced concrete has economic advantages over ordinary concrete

1. In the same strength can reduce the amount of concrete 30% à 50%;

2. Can replace or partially replace steel or reduce the diameter of the steel bar 1~2mm;

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

4. Mixing with ordinary concrete is the same, no additional equipment is needed.
