What is polypropylene fiber reinforced concrete?
Polypropylene fiber reinforced concrete (often shortened to PPFRC) is concrete that contains short polypropylene (PP) fibers mixed through the batch. The fibers spread through the paste and aggregate. They create a three-dimensional reinforcement effect inside the concrete. This helps control cracking, improves toughness, plus supports durability in many common applications. PPFRC is popular because it […]
What is PVA fiber?
PVA fiber is short for polyvinyl alcohol fiber. It is a synthetic fiber with strong bonding ability in cement-based materials. It is used in concrete, mortar, repair products, and engineered cement composites to control cracking and improve toughness. Many buyers compare PVA fiber with polypropylene fiber or steel fiber. The key difference is bonding. PVA […]
How to choose concrete fiber?
I once watched a new slab crack in weeks. I felt stuck. Choices looked messy. I now use a simple path. I match fiber to job, mix, and risk. I choose fiber by goal first. I write the performance I need. I match it to a fiber family. I check standards, dosage, and supplier proof. […]
