Top 5 Fiber-Reinforced Concrete FAQs - Euclid Chemical

Fiber-Reinforced Concrete. Fibers of different materials, architecture and dimensions will act differently during the placement, pumping, and finishing of fiber-reinforced concrete (FRC). Therefore, it is important that fibers are properly added and mixed to allow for optimum placement, pumping and finishing(see FIP # 2, Batching Fiber-Reinforced Concrete).

Macro Polymeric Fibers for Slabs on Ground| Concrete

Jun 06, 2008 · It's a mistake to plasticize concrete to high levels (such as more than 8 inches for some materials) and then introduce the MPF. The result is poor mixing. Pumping, placing, and finishing considerations. A properly proportioned mix that will pump well without fibers also will pump well with up to 7.5 pcy of MPF.
