The possibilities for the use of SHCC as a construction material have attracted the attention of the construction industries world wide due to the superior properties of this material. It shows high ductility in tension which has the ability to absorb orders more energy compared to ordinary concrete. Due to the multiple cracking phenomenon it can improve the durability of the material and so reduce the life cycle cost of a structure.
The micro-mechanical modelling and the structural benefits of SHCC have been the focus of many research groups, but certain important aspects of the material have received little attention, for example the time-dependant properties. The effect of tensile creep and creep fracture have to date not been investigated.
This paper reports on recent research done on the tensile creep and shrinkage of SHCC. Tensile creep tests were done on the macro-level as well as on the single fibre level. The effect of cracking on the creep strain was also investigated. Single fibre pull-out tests were performed to study this important mechanism of time dependence. The results of these tests are presented and the implications for time dependent behaviour of SHCC discussed.
