Cement paste; Mix design; Road construction; Slip form paving; Thixotropy; Workability
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.
