Effect of fiber types on creep behavior of concrete ...

Feb 15, 2016  Commonly used fibers, for example steel fiber, polypropylene (PP) fiber, polyvinyl alcohol (PVA) fiber and basalt fiber influence the creep behavior of concrete, which has important effect on concrete long-term deformation performance. Several authors have found out that fibers could reduce creep and shrinkage [14], [15].

Effect of fiber types on creep behavior of concrete ...

The internal defects introduced by fiber addition, i.e., the fiber-concrete interfacial zone and non-uniform fiber distribution, weakens its creep resistance. There is a clear correlation between the 28 days elastic modulus of fiber reinforced concrete (FRC) and its long-term creep behavior, indicating that they are influenced by similar factors.

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.

Structural effects of FRC creep SpringerLink

Dec 03, 2018  Long-term behavior includes aging and creep. Aging represent the change of fiber properties into the concrete environment, which may reduce the structural bearing capacity; when present, it is an important issue for the structural safety, especially when fibers are the only reinforcement. Aging of fibers must be proven by experimental tests.

Abstract The effect of different environmental conditions on the creep behavior of concrete beams reinforced with glass fiber reinforced polymer (GFRP) bars under sustained loads is investigated. This is achieved through testing concrete beams reinforced with GFRP bars and subjected to a stress level of about 20–25% of the ultimate stress of the GFRP bars.
