Abstract

Although self consolidating concrete (SCC) has been developed for more than two decades, its practical use is still limited. This is partly because its properties are not fully known and partly because its performance is highly sensitive. In the current study, an experimental program was undertaken to evaluate the robustness of eight selected SCCs. According to the obtained results, the variations of SCC robustness that determined by using innovative method (multi attribute decision making) are studied based on the variations of rheology parameters. The results indicate that there is a direct relationship between robustness and segregation resistance of SCC. Also the greatest reduction in robustness occurs in increase in yield stress together with plastic viscosity. Moreover, the scattering of compressive strength results show that there is a level of robustness in fresh state that after that the scattering of results in hardened state may be affected.
