A material model for fresh concrete pressure, if designed on a physically sound basis, enables the calculation of the formwork pressure of different kinds of concrete, depending on their rheological properties. In this paper, the concept and results of experimental and rheological investigations on fresh concrete pressure are presented. Within this experimental program a special formwork model for the fresh concrete pressure was designed. A material model is being developed, describing the behaviour of formwork pressure, depending on various aspects and materials. In order to verify and adjust this material model, a series of experiments on real formwork systems was performed.
