However, these changes lead to problems such as change in the robustness of SCC (Kwan and Ng, 2008). In other words, in order to the complete optimization of SCC mix proportion, the robustness of SCC must be considered in addition to the workability restrictions. Hence, the main objective of this study is the evaluation of the SCCs robustness self-consolidating concretes.
