Effect of fiber types on creep behavior of concrete
Creep Deformation of Fiber Reinforced Plastics-Plated
The problem of long-term creep deformation of reinforced concrete tensile elements strengthened by external fiber reinforced plastic (FRP) plates is studied. Formation of discrete cracks in concrete under tension is taken into account.
Effect of Different Steel Fiber Type and Content in Flexural
In the research study, the effect of different fiber contents to flexural behavior of the Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) was investigated experimentally. Various prismatic beam specimens with a dimension of 100×100×400 mm including two types of end-hooked steel fibers (aspect ratios: 30/0.55 and 60/0.75) in macro

Short-term and creep pull-out behavior of polypropylene
Aug 30, 2017 · In this paper, the results of short-term and creep pull-out tests of two different fiber types from a concrete matrix are considered. In the following, the fiber types are denoted as type A and type B, the latter being a newer and upgraded type A fiber. In total, 85 pull-out tests were executed with variable embedded lengths ℓ and angles θ.
Effect of fiber types on creep behavior of concrete
Fibers with elastic modulus much higher than plain concrete can clearly restrict creep, while fibers with lower elastic modulus have the opposite effect. For example, 2% volumetric blending of steel fiber reduces specific creep by 25.1%, compared with plain concrete, while 0.9 kg/m 3 mass blending of PVA fibers increases it by 19.9%. The internal defects introduced by fiber addition, i.e., the fiber-concrete interfacial zone and non-uniform fiber distribution, weakens its creep resistance.
Fiber-reinforced concrete - Advantages, types and applications
The major factors affecting the characteristic of fiber-reinforced concrete are a water-cement ratio, percentage of fibers, diameter and length of fibers. Given below are different types of fiber-reinforced concrete used in construction. Steel Fiber Reinforced Concrete. Steel fiber is a metal reinforcement.

CREEP BEHAVIOR AND DURABILITY OF CONCRETE ELEMENTS
Currently available data on the effects of creep on bond behavior of NSM CFRP strengthening systems is limited. In fact, published research on creep effects mostly focuses on the structural behavior of strengthened members and on individual components (concrete, steel reinforcement, FRP, adhesive)
Mechanisms of concrete creep. o Two phenomena are involved: 1. Time dependent deformation that occurs when concrete is loaded in a sealed condition so that moisture cannot escape. Examples of complex structures with significant effect of creep on deformation and failure behavior.
