摘要

It is important to know that change in volume to control a concrete crack. The autogeneous shrinkage due to the hydration reaction of cement was never taken into consideration by the analysis of the usual crack and design with usual concrete. Recently, it is reported that the extremely large autogeneous shrinkage occurs by the cement paste of small water-cement ratio. However, it is impossible to know the maximum or minimum value and their directions of strain because this work was carried out using buried one-dimensional strain gage. In this study, the measurement strain due to autogeneous shrinkage of cement paste is carried out using buried rosette gage. By this method, Mohr's strain circle is able to be drawn for plane strain. And it becomes that the strain on arbitrary direction is able to be obtained using this circle.
