Abstract	In recent years, high core temperatures of 77–93°C of mass concrete elements during curing have been recorded by the Florida Department of Transportation (FDOT). These curing temperatures have been recorded while still maintaining the maximum differential temperature of 20°C between the core and exterior of mass concrete elements as specified by the FDOT. This study was conducted to evaluate the strength and durability of concrete subjected to elevated curing temperatures. Using typical FDOT class IV mass concrete mixes; it is shown that elevated curing temperature resulted in lower later-age strengths. Blending the cement with fly ash and slag, resulted in increased strength and durability when compared to the plain cement mixes.Ces dernières années, le département des transports de la Floride—Florida Department of Transportation, FDOT—a enregistré des températures élevées de 77 à 93 degrés Celcius dans des blocs de béton massif en cours de séchage. Comme le précise le FDOT, ces températures de séchage ont été enregistrées alors qu’une température différentielle maximum de 20°C était maintenue entre l’intérieur et l’extérieur de ces blocs de béton massif. Cette étude fut conduite pour évaluer la solidité et la durabilité d’un béton exposé à des températures de séchage élevées. En utilisant du béton massif issue de mélanges typiques, classe IV, du FDOT, on démontre que la température de traitement élevée a eu comme conséquence des forces inférieures à un âge plus avancé. Les mélanges comportant une addition de scories et de cendres volantes se sont avérés plus solides et plus durables que ceux restés purs.
