High-modulus polymer fibers: Concretum® SUPERFIBER 40/8
High-modulus polymer fiber for limiting crack widths
Concretum® SUPERFIBER 40/8 are high-modulus polymer fibers for mortar and concrete. Their modulus of elasticity is higher than that of concrete, which helps to reduce crack widths caused by shrinkage in the long term. Unlike steel fibers, plastic fibers do not corrode.
Applications:
- Long-term crack width limitation
- Prevention of early shrinkage cracks
- Production of concrete or mortar with high fire resistance
Properties
Concretum® SUPERFIBER 40/8 are short-cut fibers made from a high-performance polymer. The modulus of elasticity of the fibers is higher than that of mortar and concrete. The tensile strength exceeds that of prestressing steel. The fine fibers exhibit a strong bond with the cement matrix, ensuring a homogeneous and high-performance building material.
Concretum® SUPERFIBER 40/8 better distributes shrinkage cracks in young concrete. Instead of a large crack, many small micro-cracks form. These are not a concern in terms of durability. Unlike conventional synthetic fibers, Concretum® SUPERFIBER 40/8 limits crack widths in the long term. The fibers are dosed minimally at 0.5 kg/m³.
Advantages:
- Long-term limitation of crack widths
- Low injury risk
- The fibers are heavier than water and sink in the settling tank
- Exposed fibers are flammable
- Very high alkalinity resistance
- No corrosion
- Easy troweling
- Low dosage: 0.5 – 3.0 kg/m³ concrete
