Özet

This study investigates the behavior of self-compacting mortar (SCM) containing calcined mud (CM) from dam and natural pozzolan (NP) subjected to high temperatures. Ten formulations were tested: one control and nine incorporating binary and ternary systems of Portland cement, CM, and NP, with substitution rates of 10%, 20%, and 30%. The compressive was evaluated at 7, 28, 90, and 180 days. SCM specimens were exposed to three high temperatures (400 degrees C, 600 degrees C, and 800 degrees C) for 2 h. Fresh properties of SCM were assessed using mini-slump and mini-V funnel tests. Results showed a reduction in superplasticizer demand for SCMs containing CM and NP. Before and after high-temperature exposure, the binary mix containing 10% of CM and the ternary mix with 5% of CM and 5% of NP showed superior compressive strength.
