Components of strain in concrete under sustained compressive stress
Strain of concrete is examined in terms of instantaneous recoverable, time-dependent recoverable and irrecoverable, defined as elastic, delayed elastic and flow respectively; experimental evidence is presented of influence on each of length of period of loading and age of concrete when load is applied; it was found that at given age rate of flow is virtually independent of any earlier loading and that delayed elastic strain tends to limiting value which varies little with age of concrete; rate of occurrence of delayed elastic strain diminishes with age of concrete and it can be linked with corresponding rate of flow.
