The corroded samples were then cut and the penetration indexes were calculated in order to measure the corrosion damage using the Image J 1.42q software (Wayne Rasband, National Institutes of Health, USA), according to the procedure described in previous paper8. Besides corrosion, the mechanical strength at high temperatures was also measured. Cylindrical samples (50 mm of height and 20 mm of diameter) were prepared and calcined at 600¡ãC. In compression testing machine with hot stage (model ZWICK Z250, Zwick GmbH & Co., Germany), the castables were fired at 1500¡ãC for 3 hours, using distinct conditions: (i) restrained expansion (correcting the load in order to keep no deformation) and (ii) expansion free (without any load). After these firing steps, the samples were broken under hot compression at 1250¡ãC under a rate of 0.002 mm/s, aiming to verify the difference between the set firing condition (with or without constraint).
