WebStructural macro-fibers have a diameter greater than 0.3 mm. Macro-fibers are used as a replacement for temperature and shrinkage reinforcement or as structural reinforcement in concrete or shotcrete. Macro fibers are used where an increase in residual (post-cracking) flexural strength is required (e.g. ASTM C1609 or EN 14845). WebSep 7, 2024 · Fiber Reinforced Shotcrete. September 7, 2024. Shotcrete, simply put, is spray-applied concrete. Concrete is pumped through a hose and projected at high velocity onto the desired surface.
