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

2016-2-15  Chem studied the influence of temperature and humidity on the deformation performance of SFRC and discovered that steel fiber can reduce the shrinkage and creep of cement-based material, and lower the effect of temperature on concrete creep as well. However in practical project, the increase of water–cement ratio, in the hope of improving FRC ...

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%.
