Steel fiber Compared with Synthetic macrofibers
Compared with steel fibers that are widely used in engineering applications, synthetic macrofibers have many performance advantages

Performance	Steel fiber	Synthetic Macrofiber
Improve the toughness of concrete	High cost per square meter of concrete	Low cost per square meter of concrete
Improve the crack resistance of concrete	High cost per square meter of concrete	Low cost fiber per square meter of concrete
Maintain durability	Poor durability, easy to rust, and the performance of steel fibers deteriorates sharply after rusting	Good durability, inert materials have long-lasting and long-lasting performance in concrete, with almost no attenuation
Dispersion in concrete	Easy to agglomerate, poor dispersibility	Easy to disperse
Influence on the fluidity of concrete	Rigid fibers have a skeleton effect, which has a significant impact and is prone to exposure during plastering. However, due to their high rigidity, plastering is difficult	Flexible fibers have minimal impact and are easy to flatten
Rebound of sprayed concrete fibers	Fiber rebound is large, which can easily cause injury	Low fiber rebound
Friendliness	Excessive wear and tear on mixers, concrete pumps, and pipeline equipment	Wear free and easy to use

****FD300T One type synthetic macrofibers
The current applications of synthetic macrofibers include:
Spray concrete: initial support for tunnels, permanent support for underground powerhouses, slope stability, structural reinforcement, etc; Prefabricated concrete components: RPC trench cover, manhole cover and other concrete cover plates, concrete pipe segments and blocks, concrete piles, etc;
Concrete slabs: industrial flooring, building floor slabs, highway pavements, airport runways, dock surface layers, channel lining, bridge deck pavement layers, dam panels, etc;
Other: underground structure concrete side walls, top and bottom plates, retaining walls, water storage tanks, offshore platforms, bridge piers, etc.
The commonly used synthetic macrofibers in the market like
FedFiber ® FDM400,FDM600,FD600T,FD300T, etc. Synthetic macrofibers, due to their unique properties, are gradually replacing steel fibers in many concrete projects and have become an important component of fiber-reinforced concrete.
