Creep of concrete is a time dependent phenomenon. It affects the safety and serviceability of concrete structures. While number of models has been developed by researchers to predict the creep of concrete, the performance of these models suggests that there is considerable scope for improvement. In this paper, an attempt is made to compare the performances of two models for basic creep of concrete, viz. dissolution precipitation mechanism (DPM) based model and DPM with modified adaptive link mechanism (MDPM) proposed in the literature. From the limited studies, it is noted that basic creep compliance prediction obtained from the MDPM model is in good agreement with the experimentally reported creep compliance values.
