Pull-Out Behavior of Single Fiber Embedded in Porosity Free Concrete(PFC)
Pull-out behavior of single fiber embedded in Porosity Free Concrete (PFC), which is a non-porous ultra high strength matrix, was experimentally investigated. Four types of fibers were used: steel fiber, stainless steel fiber, bundled aramid fiber, and bundled PBO fiber. Two kinds of embedment length (2 mm and 5 mm) were adopted in the test. Regardless of the difference in embedment length, the maximum load was in the order of stainless steel fiber, steel fiber, aramid fiber, and PBO fiber. Regarding the shape of the load-displacement curve, steel fibers, aramid fibers, and PBO fibers showed softening behavior after the maximum load, whereas stainless fibers showed yielding behavior that caused displacement while maintaining the load. It seems that the stainless fiber has good bonding with the ultra-high strength matrix.
