Abstract

Recently, cracks in a few prestressed concrete (PC) structures at their early ages have been found in Japan. It was detennined that cracking was caused by large drying shrinkage of the concrete. Therefore, large test specimens whose sizes are the same as a real PC box girder were constructed and the drying shrinkage strain was measured over an extended period of time. This measurement helped explain what had happened in the real structures, and a clue to solve the problem of excessive drying shrinkage strain was obtained. In addition, it is now possible to predict damage to concrete caused by drying shrinkage with the analysis based on the moisture diffusion in concrete.
