CREEP OF LIGHTWEIGHT AGGREGATE CONCRETE UNDER VARIABLE STRESSES

The creep of lightweight of aggregate concrete under constant stress is described by a logarithmic function of time, and the variations of the coefficients with age are experimentally determined. Using the relation thus obtained, an attempt is made to predict the creep of lightweight concrete specimens with the same composition under stepwise varying stresses, assuming a linear viscoelastics behavior. It was established that there is good agreement between the predicted and experimental values.
