Fiber Types According to ASTM C1116 & EN 14889-2
ASTM C1116 – Standard Specification for Fiber-Reinforced Concrete
According to ASTM C1116, fibers used in fiber-reinforced concrete are classified into four main types:
Steel fibers made from carbon or stainless steel, typically used to improve the structural performance, toughness, and crack resistance of concrete.
Alkali-resistant glass fibers designed to resist the alkaline environment of concrete. These fibers are mainly used for controlling plastic shrinkage and temperature cracking, and in some cases, for structural reinforcement.
Synthetic fibers produced from polymers such as polypropylene, polyethylene, nylon, or polyester. They are used to control plastic shrinkage cracking, improve impact resistance, and enhance durability.
Fibers derived from natural sources such as cellulose, sisal, jute, or coconut. These are primarily used for controlling plastic shrinkage and temperature cracking, and are less common in structural applications.
Definitions of Microfibers and Macrofibers According to ASTM C1116 EN 14889-2
According to ASTM C1116 & EN 14889-2, microfibers are defined as fibers with a nominal diameter less than 0.3 mm (300 microns) and a length typically less than 19 mm. Microfibers are primarily intended to control plastic shrinkage cracking and to reduce settlement cracking in concrete. They are generally not considered to provide significant post-crack load-carrying capacity.
Macrofibers, as defined by ASTM C1116 & EN 14889-2, are fibers with a nominal diameter equal to or greater than 0.3 mm (300 microns) and a length typically greater than 19 mm. Macrofibers are designed to provide post-crack load-carrying capacity, improve toughness, and enhance the structural performance of concrete. They are used as an alternative or supplement to traditional steel reinforcement in certain applications.
Key Terminology in Fiber-Reinforced Concrete
Aspect Ratio:
The ratio of the fiber’s length to its equivalent diameter. Mathematically, a higher aspect ratio generally enhances the fiber’s effectiveness in crack control and mechanical performance.
“Aspect Ratio: Fiber Length / Fiber Diameter”
Equivalent Diameter of a Fiber:
The diameter of a hypothetical circular fiber having the same cross-sectional area as the actual (possibly non-circular) fiber. It is used to standardize comparisons between different fiber shapes.
Monofilament Fibers:
Single, continuous, and fine fibers, typically made from synthetic materials such as polypropylene. They are primarily used to control plastic shrinkage cracking in concrete.
Equivalent Flexural Strength:
A parameter defined by ASTM C1609 that measures the post-crack load-carrying capacity of fiber-reinforced concrete. It is calculated based on the average load sustained by the specimen at specified deflections during a flexural test.
Equivalent Flexural Ratio:
The ratio of the equivalent flexural strength to the first-crack flexural strength of the concrete. It indicates the post-crack performance provided by the fibers.
Flexural Strength:
The ability of concrete to resist failure in bending. Fiber reinforcement can enhance the flexural strength of concrete.
Toughness:
The energy absorption capacity of concrete after cracking, representing its ability to withstand deformation and dissipate energy. Fibers significantly improve the toughness of concrete, reducing the risk of sudden failure.
Crack:
A separation or fissure in concrete resulting from loading, shrinkage, or other effects. Fibers help delay crack formation and limit crack width.
Denier:
A unit of measurement for the linear mass density of fibers, defined as the mass in grams per 9,000 meters of fiber.
“Denier: Mass in grams / 9,000 meters”
Ductility:
The capacity of concrete to undergo significant deformation before failure. Fiber reinforcement increases the ductility of concrete, making it less brittle.
Number of Fibers:
The total number of individual fibers present in a given volume (typically 1 m³) of concrete. This depends on the fiber dimensions and dosage.
Fiber Dosage Rate:
The amount of fiber added to the concrete mix, usually expressed in kilograms per cubic meter (kg/m³).
Fiber Volume Fraction:
The volumetric proportion of fibers within the concrete mix.
“Fiber Volume Fraction: Volume of Fibers / Total Volume of Concrete”
It is typically expressed as a percentage (%).
