Abstract
The paper reports a study to assess the relationship between slake durability indices and uniaxial compressive strength, Schmidt hardness, P-wave velocity, modulus of elasticity, effective porosity, water absorption and dry and saturated unit weight for seven types of carbonate rocks obtained from south west Turkey. It was found that the dry unit weight, saturated unit weight and Schmidt hardness gave the best relationship with first cycle slake durability (r = 0.99) while uniaxial compressive strength has a strong relationship with fourth cycle slake durability (r = 0.94). The results showed little difference in the correlation coefficients obtained after the fourth cycle. It is concluded that, for the rocks studied, the first and fourth cycles provide sufficiently good data on the durability for preliminary engineering/design works and that the second to fourth cycle results could be estimated using the first cycle slake durability index (r = 0.99–0.97).
Résumé
L’article présente une étude destinée à évaluer les relations entre les indices d’altérabilité et la résistance à la compression simple, la dureté de Schmidt, la vitesse des ondes P, le module d’élasticité, la porosité efficace, l’absorption d’eau et les poids spécifiques sec et saturé pour sept types de roches carbonatées du sud-ouest de la Turquie. Le poids spécifique sec, le poids spécifique saturé et la dureté de Schmidt des roches donnent la meilleure corrélation avec Id1 (r = 0,99) tandis que la résistance à la compression simple présente une forte corrélation avec Id4 (r = 0,94). Les résultats ont montré une faible différence de coefficients de corrélation obtenus après le quatrième cycle dans l’essai d’altérabilité. Il est conclu que, pour les roches étudiées, les Id1 et Id4 fournissent des données suffisamment bonnes sur l’altérabilité pour des études d’ingénierie préliminaires et que les indices Id2 à Id4 pourraient être estimés en utilisant le premier cycle de l’essai d’altérabilité (r = 0,99 à 0,97).
