Creep and Shrinkage of Concrete-Kinetics Approach

Abstract

This paper discusses possible mechanisms of basic creep and autogenous shrinkage and couplings. The starting point is a kinetics analysis of the basic creep of different types of concrete and a high performance concrete. This approach reveals two domains: short term creep kinetics, active for some days after loading, and long term creep kinetics, characterized by a pronounced and non-asymptotic aging. The paper also presents some preliminary experimental results on the creep dilatancy behavior of concrete.
