Concrete creep and shrinkage investigations at Auckland University

The paper describes various experimental creep and shrinkage investigations. Results for the creep and shrinkage of a typical bridge building concrete are presented for specimens kept inside a laboratory and on top of, inside, and underneath a concrete box girder bridge. The environment is shown to have considerable effects on creep and shrinkage but it is concluded that location at the bridge was relatively unimportant. Sets of experiments in which the effect of size or thickness and the effect of age of loading on creep and shrinkage are described and some preliminary results are presented. Code predictions are compared to some of the experimental results and it would appear the ceb-fip predictions of shrinkage are about half of the experimental values and creep predictions are of the correct order.
