Abstract	This study reports an investigation into the physical and mechanical characteristics of fine-grained (alabastrine) and coarse-grained (porphyritic) gypsum from Sivas, Turkey. The geotechnical properties improved as the grain size decreased. The Student’s t test indicated that the differences reported between the mean values of the slake durability, Schmidt hardness, unconfined compressive strength, Young’s modulus, and tensile strength of the two types of gypsum were statistically significant. The results indicate that texture, especially grain size and shape, is an important parameter controlling the differences in the mechanical properties of the two gypsum types studied.L’étude réalisée porte sur les caractéristiques physiques et mécaniques d’un gypse à grain fin (variété d’albâtre) et d’un gypse à grain grossier (variété porphyrique) provenant de la région de Sivas en Turquie. Les propriétés géotechniques sont d’autant meilleures que la taille des grains est fine. Le test de Student a été appliqué pour comparer les valeurs moyennes relatives aux essais d’altérabilité, de dureté de Schmidt, de résistance à la compression simple, de module d’Young et de résistance à la traction, valeurs concernant les deux types de gypse. Les résultats ont indiqué que la texture, principalement la taille et la forme des grains, est un paramètre important contrôlant les différences de comportement mécanique des deux types de gypse étudiés.
