Dans ce contexte, le travail que nous entamons est essentiellement à caractère expérimental, a pour objectif principal de mettre en évidence l’évolution de la résistance mécanique en compression avec la température. </span>Pour ce faire, la compagne d’essai du comportement « à froid » de béton a été réalisé sur trois compositions ayant des rapports E/C respectivement égaux à 0.60, 0.65 et 0.70
