Influence of Mixing Procedure on Robustness of Self-Consolidating Concrete

Self-Consolidating Concrete (SCC) is, in the fresh state, more sensitive to small variations in the constituent elements and the mixing procedure compared to Conventional Vibrated Concrete. Several studies have been performed recently to identify robustness of SCC and to develop solutions to increase the robustness of SCC. Ghent University obtained a major research project from the Research Foundation in Flanders (FWO) to investigate fundamentally robustness of SCC and to identify potential solutions in the form of alternative materials to enhance robustness. In the proposed research project, Missouri Science and Technology (S&T) intends to extend the research at Ghent University by investigating the influence of the mixing procedure on the robustness of SCC. The project is split into four tasks. In the first task, the sequence of adding the constituent elements and mixing will be investigated by measuring the rheological properties of the produced mortars. In the second task, the consequences of the main influences of the mixing procedure will be compared to the influence of small variations of the most important constituent elements. In the third task, the results obtained on mortars are validated on concrete scale, while in the fourth task, the robustness of thixotropy and loss of workability will be investigated on concrete scale. The research team hopes in this way to acquire more knowledge on the influence of the mixing procedure on the robustness of SCC, enabling the establishment of a set of guidelines. As a result, the practical application and perception of SCC in the construction and transportation industry can be enhanced.
