Effect of fiber types on creep behavior of concrete

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.

Creep of Cracked Fiber Reinforced Concrete by Megha ...

the subject of compression creep of concrete is well developed, use of concrete under tension loads has been limited at best due to brittleness of concrete. However with the advent of using fiber reinforced concrete, more and more applications where concrete is expected to carry tensile loads due to incorporation of fibers is gaining popularity.

Creep of polymeric fiber reinforced concrete: A numerical ...

Jun 01, 2020 · Research has shown that the creep behavior of cracked FRC can be attributed to the combined effect of the creep behavior of (1) individual fibers, (2) the fiber-matrix interface and (3) the concrete matrix , . In most structural design codes, the interaction between fibers and matrix is not explicitly taken into account, but FRC is rather considered to be a one-phased material.

Effects of Temperature and Stress on Creep Behavior of PP and ...

Aug 22, 2019 · Creep of Steel fiber reinforced RPC at high temperature was investigated by Abid et al. . Results showed that creep increased with increasing stress level and temperature. Since different fibers types have different effects/mechanism under high temperature, therefore their high-temperature creep behavior should be studied separately for RPC.
