a X-ray diffraction results show the existence of sulfate phases achieved from the powder prepared from the surface and the middle of the samples of ATAF1 mixtures cured at 20 ± 2, 40 ± 2 and 60 ± 2 °C and immersed in sulfate solution. b X-ray diffraction results show the existence of sulfate phases and achieved from the powder prepared from the surface and the middle of the samples of ATAF2 mixtures cured at 40 ± 2 and 60 ± 2 °C immersed in sulfate solution. c X-ray diffraction results show the existence of sulfate phases and achieved from the powder prepared from the surface and the middle of the samples of ARSH mixtures cured at 60 ± 2 °C and ACSH mixtures cured at 20 ± 2 °C immersed in sulfate solution.
