Over the last 25 years CHRYSO has developed a unique comprehensive know-how regarding Fibre-Reinforced Concrete (FRC).
The right use of fibres has many benefits for the concrete. They increase its structural performance and durability. Fibres are also used to control cracking due to plastic and drying shrinkage.
Fibre-Reinforced Concrete (FRC) expertise is especially based on :
CHRYSO provides a large and innovative range of natural and synthetic fibres.
Combined with CHRYSO®Fibre Expertise , customers enjoy the value created by a global, optimized and easy-to-use FRC solution supported by in-field experts.
Micro fibres are mainly used against the formation of plastic shrinkage cracks. This leads to an improved durability and a better aesthetic.
CHRYSO natural micro fibres can be used to optimize your concrete carbon footprint.
Macro-synthetic fibres enhance durability, thoughness and the ability to provide structural capacity when properly designed.
These fibres are easier to use compared to steel fibres due to steel fibres due to lighter weight, a non-corrosive nature and the ability to be pumped with ease.
BENEFITS from the CHRYSO®Fibre solutions
Reduced shrinkage
induced cracking
Microfibres reduce very efficiently the risk for plastic shrinkage induced cracking.
Time saving vs traditional reinforcement
Fibers considerably facilitate contractors’ job through the suppression of expensive and stringent steel mesh cutting and overlap or incorrect positioning.
Durability
improvement
Most demanding surface finish quality, including decorative concrete
CO2
optimization
CHRYSO® fibres can reduce the projects’ carbon footprint
CHRYSO®Macrofibre range is used as an alternate system to conventional reinforcing such as wire mesh and steel rebar in residential floors, foundations and toping slabs. Use of CHRYSO Macrofibres fast tracks the completion of the project while allowing for superior durability and significant savings.
Depending on the screed technology used and local regulation, fibres are often used to enhance the robustness (cracking control) of self leveling screeds. CHRYSO offers high performance fibres designed to preserve the perfect finish and high pumpability required for high flowability screeds.
CHRYSO fibres are also compatible with heated floors. No disruption, just higher performance.
Spalling may be a violent effect to fire-exposed concrete destroying the entire cross-sections or reducing the load-bearing capacity of a construction substantially. The network of large capillaries created by vaporized fibres allows for internal steam exhaust, thus preventing fire-spalling for several hours.
CHRYSO offers a full range of proven anti-fire spalling fibres and its expertise in adapted mix designs, especially for tunnel segments.
As a part of its complete range of tunneling solutions, CHRYSO dedicated macro-fibres allow for meeting the requirements of class
A, B and C shotcrete (EFNARC or ASTM standards). These fibres are designed for easy pumping, maximum rebound reduction and ultimate tensile strengths performances.
Combined with CHRYSO®Jet range of admixtures and our dedicated concrete mix-design know-how, they ensure a flawless and successful operation throughout the project.

PATENTED SOLUTION FOR PIPES
CHRYSO® Macrofibres are also used to replace conventional
steel reinforcement in concrete pipes. This patented solution is a breakthrough as it allows for drastic performance enhancement and cost savings. Especially: no need for steel reinforcement manufacturing and superior pipe durability in aggressive environments.
PRECAST VAULTS, MANHOLES, PANELS
CHRYSO®Fibre solutions can bring value to a wide range of precast applications. Cracking control, elements lightening, durability enhancement, steel cost reduction are only few examples of the results at the reach of your hand.
CHRYSO’s offer combines a unique mix design expertise and a wide range of fibres compatible with almost all precast processes andconcrete element specifications.
Synthetic fibers, help protect fresh concrete from shrinkage induced cracking (caused by rapid surface dessication) and thermal cracking (caused by stresses as the concrete heats up during curing and then cools off). Once the concrete has hardened, they help cracked sections hang together.
Fibres also prevent segregation.
Natural fibres improve the concrete hydration process and enhance color and surface finish..
CHRYSO®Fibre UF-500 is the first cellulose based microfiber available in the market CHRYSO®Fiber UF-500 is produced based on renewable and biodegrable raw materials The hydrophilic nature of cellulose fibers is especially valuable when working with decorative surfaces. CHRYSO®Fibre UF-500 offers a technical response to cracking control.They allow for increasing further the sustainable development approach. The fineness of CHRYSO®Fibre UF-500 as well as the density of fibers per m3 favors its anchoring to the cement matrix Cellulose fiber absorbs pigment, dye, and stain, providing deeper color to the decorative surface.
Every day, CHRYSO supports its customers with specific services and a unique range of technologies dedicated to FRC. CHRYSO provides full dimensioning and mix-design optimization service.
