Details

High-performance fibre for cement-based mixes. Designed for GFRC, ECC, and decorative concrete, AC50 helps control plastic shrinkage, reduce cracking, and improve cohesion without affecting finish quality. Dosages vary from 0.4-0.6% of cementitious content, typically used alongside complementary fibre systems.

Additional information

Alpha Acrylic Fibre AC50 is a premium monofilament acrylic fibre engineered for use in concrete, GFRC and cementitious mix designs requiring enhanced reinforcement and crack resistance. Unlike bundled fibres, AC50 fibres feature a higher surface area, allowing for improved interaction within the mix and more effective dispersion throughout the matrix.

Due to their fine monofilament structure, AC50 fibres should be carefully introduced into the mix to avoid clumping or thickening of the material. Some users achieve optimal dispersion by blending the fibres into the mix water first, while others prefer gradually adding the fibres during the mixing process. The ideal method can vary depending on the mix design, equipment and application, so minor experimentation is recommended.

Suitable for a wide range of precast, cast-in-place and decorative concrete applications, Alpha Acrylic Fibre AC50 helps improve mix cohesion, reduce shrinkage cracking and support overall durability and performance.
