Rheological properties of self-consolidating concrete made by crushed waste tile aggregates

In recent decades, the use of self-consolidating concrete has become widespread. Hence, recognizing the various properties of self-consolidating concrete are essential. In this study, several mixture designs have been tested and final mixture design of crushed tile aggregates which were replaced by 0%, 25 %, 50%, and 100% volume percentage of natural aggregates were conducted. To evaluate fresh properties of SCC, slump flow and rheometer tests were carried out. Results show that the percentage of fine aggregates has a significant impact on the properties of self-consolidating concrete. In addition, the results of rheometer test show by increasing the percentage of recycled aggregates increases yield stress and plastic viscosity, significantly.
