Made of polypropylene Durus S500 has been proven to be a valid alternative to steel rebar in the manufacture of precast cement elements. This reinforcement not only maximizes yield, but also contributes to improved workplace safety and a long service life of precast concrete.
If fibers are too long, uniform distribution of the fibers becomes difficult. Longer fibers can be used when larger aggregates are present to shear the bundles of fiber apart. Short fibers are used with small or lightweight aggregate. Polypropylene fibers tend to hold the concrete mix together.

Mixing Fiber Reinforced Concrete (FRC) is different from traditional concrete in how it lacks large aggregate or pebbles and is blended with paddle mixers instead of the large drum mixers associated with a traditional concrete mix. Fiber reinforced concrete contains only fine sands, portland cement, fibers, and chemistry to accelerate its cure ...
Polypropylene fibre concrete. Polypropylene fibre concrete contains thousands of individual fibres which are evenly dispersed throughout the concrete during the mixing process, this creates a matrix-like structure that provides additional benefits to concrete such as long-term durability and toughness.
Our office, Allegheny Design Services, has examples on exterior slabs-on-grade of over 20 years old, with only fiber reinforcing that still exhibits no cracks. The use of fiber does not have a major effect on the compressive strength of the concrete. Several types of fiber exist. They include steel, glass, synthetic and natural fibers.

The fibers for micro products are made primarily from nylon or polypropylene, each having the same effect on concrete, while macro fibers are typically made of polypropylene and related co-polymers
FRC 850 BLENDED FRC-850 BLEND is a blend of low carbon drawn wire fibers and polypropylene synthetic micro fibers. The combination of the two proven fiber types provides a reinforcement system that addresses plastic shrinkage as well as restrained shrinkage in concrete slabs.
The effect of the sulfuric acid attack on Geopolymer Concrete reinforced with micro polypropylene fibres is also discussed. The results show that hydrophobic characteristics of the micro polypropylene fibre led to weak contact with the geopolymer binder and hence weakened the mechanical performance of the fly ash based geopolymer matrix.
GRACE MICROFIBER TM Synthetic fiber for concrete ASTM C1116, ASTM C94 Product Description Grace MicroFiberTM is a synthetic fiber for concrete, manufactured from 100% virgin polypropylene in a microfilament form. Grace MicroFiber is produced on a state-of-the-art production line which is specifically designed to yield an ultrathin concrete ...
The results revealed that the addition of both 6 and 12-mm fibers enhances the behavior of concrete significantly. The mixes containing 2 kg/m 3 polypropylene fibers showed the best performance. It was also concluded that 6-mm fibers have a better effect on energy absorption (an increase of 69 %) over 12-mm fibers, which showed a better effect ...
Description. Polypropylene (PP) fiber curved form is a kind of high-strength fibers for concrete anti-cracking reinforcement. Put into concrete or mortar, they can disperse quickly and effectively reduce the crack caused by plastic shrinkage, sedimentation, temperature changes and other factors, further prevent and inhibit the formation and development of cracks in concrete.
These unique fibers add superior bonding properties to the concrete matrix. The result is crack control and an extended service life of the concrete. Synthetic macrofibers, are manufactured from a proprietary blend of polypropylene resins, in compliance with ASTM C 1116/C 1116M. Macrofibers are specifically engineered for use as shrinkage and ...

Steel fiber reinforced shotconcrete are widely used at home and abroad, compared to the ordinary modelconcrete, this process is not only convenient, fast, and often used in places with poor geological conditions. In this paper, we use mercury intrusion method to test pore structure of steel fiber reinforced shotconcrete, and analyze the change of pore structure under different construction ...
Use of SINTA™ F Fibers reinforces a fresh concrete mixture while its tensile strength is weakest by mechanically locking into the concrete matrix. Plastic shrinkage cracking and permeability are both reduced. At the same time, SINTA™ F Fibers increase impact, abrasion, shatter and fire-spalling resistance of the concrete.
SI offers polypropylene (PP) fibers, steel fibers, macrosynthetic fibers and engineered blends. According to Payne, SI's polypropylene fiber products are critical for controlling "early age" plastic shrinkage cracks to prevent these cracks from growing into major flaws as the concrete cures.
Oct 12, 2016 · STRUX® BT50 macro synthetic fibers--a reinforcement component of the TYTRO® Shotcrete System--do not corrode like steel fibers and provide enhanced durability for superior crack control in concrete.

It is also stated within C1116 that polypropylene based fibers are known to be durable within concrete. Although micro-synthetic fibers provide superior resistance to the formation of plastic shrinkage cracks versus welded wire reinforcement, they are unable to provide any resistance to further crack width openings caused by drying shrinkage, structural load or other forms of stress.
Micro-Synthetic Fiber, Fibrillated . PSI FIBERSTRAND F is a fibrillated polypropylene micro-fiber for concrete reinforcement that complies with ASTM C 1116, Standard Specification for Fiber Reinforced Concrete and Shotcrete, and is specifically designed to help mitigate the formation of plastic shrinkage cracking in concrete.

This paper presents a research of abrasive resistance of classic concrete and micro-reinforced concrete with two types of polypropylene fibers. Water/cement factor was varied from 0.5 to 0.7, while the content (in%) of the remaining components remained constant.
CONSTRUCTION POLYPROPYLENE (PP) FIBRES – CPP40 . These are Polypropylene (PP) macro fibers of 40 mm length for reinforcement in concrete. The long length of the fibre holds different components of concrete together, thereby providing a better reinforcement thus increases the strength and properties of concrete.

Fiber Reinforced Concrete can be defined as a composite material consisting of mixtures of cement, mortar or concrete and discontinuous, discrete, uniformly dispersed suitable fibers. Fiber reinforced concrete are of different types and properties with many advantages.
Polypropylene is the most commonly used fiber these days. Nylon is more expensive and has properties that are not as amenable to good performance for the intended purpose in concrete...I'm sure someone will disagree with that statement, but that's my opinion. I am not a fan of "plastic" fiber in concrete.
