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

2016-2-15 · 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 ...

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%.

Effect of Fibre Reinforcement on Creep in Early Age Concrete

2021-12-28 · This research analyses the strain behaviour of fibre-reinforced concrete (FRC) in the event of a creep episode. The analysis of creep experienced by FRC specimens during the test reflects better performance than that predicted by the EHE-08 standard. The authors propose a formulation for the evaluation of creep strain undergone by FRC. During the research, the

Effect of fibre dosage and stress-strength ratio on creep ...

2021-10-1 · The PP FRAAS concrete did not exhibit any significant linear creep behaviour. With the increase of fibre dosage, the inhibition effect of fibres first became stronger and then became weaker. The inhibition effect of the fibres was gradually intensified with the increasing stress–strength ratio. As the fibre dosage increased from 0 to 0.9% ...

Effect of Fibers on Durability of Concrete: A Practical Review

2020-10-14 · Various types of micro and macro fibers have been used as a secondary reinforcement in concrete. Fiber reinforced concrete (FRC) is a special class of concrete which incorporates fibers in the formulation to enhance its resistance to (tensile) loads. Different classes of FRC with varying advantages have been developed.

Creep in Concrete Topic

2021-11-1 · Creep is indicated when strain in a solid increases with time while the stress producing the strain is kept constant. In more practical terms, creep is the increased strain or deformation of a structural element under a constant load. Depending on the construction material, structural design, and service conditions, creep can result in significant
