Rapid Pavement Construction: Research on Thixotropy and Workability Loss of Vibration-free Concrete in View Accelerating Pavement Construction by Slipforming

The main objective of this project is to identify critical constituent materials and mix design parameters that influence the thixotropy and workability loss of vibration-free concrete. The research will be mainly performed on cement-pastes, which is the source of thixotropy and workability loss. The influence of the aggregates will be investigated in a separate task. Understanding the time-dependent fresh concrete behavior is essential for the development of vibration-free concrete for slipforming, enhancing the opportunities for accelerated pavement construction. Furthermore, the obtained results can be related to other Research on Concrete Applications for Sustainable Transportation (RE-CAST) projects, such as project 1B on formwork pressure and 1C on the influence of casting procedures on the performance of concrete.
