Abstract
Relative movements, prior to and during the initial setting of the grout, are to be regarded as particularly critical for the structural soundness of grouted connections. Currently, the expected relative movement during grouting shall be limited to a maximum of 1 mm, whereby the behavior of the structure is based on ungrouted piles. However, it can be assumed that the grout contributes to the stiffness of the structure in a significant manner. In order to consider the grout-stiffness during the design process, methods for determining the development of grout-stiffness under the influence of early-age movement are required. The goal of the presented research was to develop such a method, which is based on rotational and oscillatory rheology and will be presented in the following.
