ABSTRACT
For durability design and/or prediction of life time of concrete structures, nowadays it is essential to apply some relevant mathematical models to simulate the time-dependent behaviour of concrete.
Cementitious materials such as concrete have complex multi-component and multi-scale structures that first form through chemical reaction and then continue to change with time (e.g. Jennings et al. 2008). As a result, various aspects of the behaviour have been observed but sometimes the real mechanisms are not clarified. If the observed behaviour is just simplified as a material law, the potential of modern numerical methods for computerized structural design is not fully used.
