Figure 3.21 illustrates the stress induced when concrete is subjected to early-age temperature history. After placing a large mass of concrete, the temperature rise due to the heat of hydration generated causes the interior of the concrete to become hotter than the surface layers, where heat is lost to the atmosphere unless the mass is completely insulated. The consequent differential

Tag: Creep Creep (Dimensional stability)

Creep is defined as the gradual increase in strain with time for a constant applied stress after accounting for other time-dependent deformations not associated with stress, namely, shrinkage or swelling and thermal strain. Hence, creep is reckoned from the elastic strain at loading, which depends upon the rate of application of stress (see Section 3.2) so that the time taken
