The knowledge of the rheological properties of cement based grouting materials is of outstanding significance for their workability and applicability. However, it usually takes extensive efforts to optimize these materials as their rheological properties may differ in a wide range dependent on the physical properties of the selected source materials. By means of a case study the procedure regarding the development and rheological optimization of cement based grouting materials is presented in this paper. The research is part of a German-Indonesian joint project, funded by the German Federal Ministry of Education and Research (BMBF), where the storage, distribution and treatment of water has to be assured by durable concrete structures. Comprehensive rheological investigations are presented which provide the database for the optimization of grouting materials with regard to their intended range of application. Against this background it is the aim of this study to derive a physically sound prediction model which quantifies the interactions between the different source materials used. It is modular constructed and reveals an enormous optimization potential in the development of novel, cement based grouting materials. From a technical and economical point of view, the control of the rheological behavior of cement based grouting materials is the key factor to achieve optimal construction results.
