RESBUILD PP FIBRE is a specially treated, chemically inert polypropylene fibre reinforcement designed for concrete and mortar applications that demand high crack resistance, improved durability, and long-term structural performance. The fibres are non-corrosive and engineered to disperse instantly and uniformly throughout the concrete mix, ensuring consistent reinforcement across the entire structure.
In modern construction, controlling shrinkage cracks and improving concrete durability are essential for achieving longer service life and reducing maintenance costs. RESBUILD PP FIBRE provides multidirectional secondary reinforcement that effectively minimises plastic shrinkage cracks, thermal cracking, and micro-crack formation while significantly improving the toughness and integrity of concrete and mortar.
The product conforms to ASTM C-1116-89 standards, making it suitable for residential, commercial, industrial, and infrastructure construction projects.
Performance and Working Mechanism
Concrete is naturally prone to shrinkage and thermal stresses during the hydration and curing process. These internal stresses often lead to microcracks that reduce structural strength and allow water penetration, resulting in long-term deterioration.
RESBUILD PP FIBRE helps control these issues by forming a uniform three-dimensional reinforcement network within the concrete matrix. Once added to concrete or mortar, the fibres disperse rapidly and distribute evenly throughout the mix, ensuring effective crack control at every stage.
This reinforcement system reduces crack formation during both the plastic and hardened stages of concrete. It improves cohesion within the mix and enhances resistance to stresses caused by drying shrinkage and temperature variations.
The fibres also help reduce the rate of heat evolution by distributing hydration heat over a longer period. This controlled heat release minimises thermal stress and significantly reduces temperature-related cracking in slabs, floors, pavements, and mass concrete applications.
In addition to crack control, RESBUILD PP FIBRE improves tensile strength, compressive strength, fatigue resistance, and impact resistance while reducing permeability and enhancing long-term durability.
