Tensile creep behavior of high strength concretes at early ages

Early age tensile creep of high strength concrete loaded during the first day after casting was studied. The effect of silica fume was evaluated, using two types of loading scheme: (i) creep which occurs in a restrained autogenous shrinkage test and (ii) creep measured in a conventional test under constant load. The two methods showed that the addition of silica fume increased the early age ...

following example is for modeling the creep behavior of an engineering material. Creep is a very slow process in which a material continues to deform with time under constant stress. Materials that exhibit creep deformation are time-dependent. The relationship that governs

Structural effects of FRC creep

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.
