Behavior of self-compacting concrete made with marble and tile wastes exposed to external sulfate attack

To evaluate the behavior of the concrete samples against different forms of external sulfate attack, the change in their masses was monitored as well as the determination of their dynamic elastic modulus by the ultrasonic test was performed. Multiple measurements of these properties were taken for each 60 days of exposure and up to twenty months period. The results of the carried out testing showed that SCCWs have good resistance to external sulfate attack, even in severe exposure to the sulfate with sodium sulfate solution, and especially for the self-compacting concrete made with marble waste.
