This study addresses the challenges of understanding the complex mechanisms of concrete behaviorunderfire, particularly damageandspalling. Usingastandardizedmortar,extensivethermal, mechanical, transport and microstructural characterizations were conducted to provide input data for a thermo-hygro-chemo-mechanical model. Preliminary results highlight the impact of elevated temperatures on the integrity of mortar, providing insight into the degradation mechanisms that affect its structural performance under thermal stress.
