Synthetic Macro Fiber VS Steel Fiber
Among fiber concrete reinforcement materials, steel fiber and synthetic macro fiber are the two most common types of materials. Steel fiber is more traditional, has a longer history of use, and its low price makes it widely used in concrete engineering. However, steel fiber has its own disadvantages-high specific gravity, easily corroded, and can damage tools during use. Synthetic macro fiber is a new type of material that began to appear in the middle of the last century. The material is rich in raw materials, has strong processability, low specific gravity, and good corrosion resistance. It can exist in concrete for a long time without damage to its performance.
There are many differences between synthetic macro fiber and steel fiber.
In terms of material, one is made of polypropylene and the other is steel.
In terms of weight, polypropylene imitation steel fiber is lighter, which makes it more convenient in transportation and construction operations.
In terms of corrosion resistance, polypropylene imitation steel fiber has a natural advantage and is not easy to rust and corrode, while steel fiber is easily corroded in some harsh corrosive environments.
In terms of elastic modulus, the two are also different, which leads to differences in their action mode and effect when reinforcing the matrix.
In terms of dispersibility, polypropylene imitation steel fibers can usually be better dispersed in the matrix, while steel fibers may agglomerate, affecting the reinforcement effect.
In terms of price cost, polypropylene imitation steel fibers are relatively low, which can reduce the material cost of the project to a certain extent.
