Abstract
The paper describes the change in physical and strength properties due to weathering of three crystalline rocks – granite, basalt and quartzite. It draws attention to the relationship between unconfined compressive strength and other measurements such as the point load index, the Brazilian tensile strength and the Schmidt hammer rebound number. The strength recorded is negatively related to the porosity which is considered an important indicator of the weathering state.
Résumé
L'article décrit les variations des propriétés physiques et mécaniques de trois roches: un granite, un basalte et un quartzite, en fonction de leur degré d'altération météorique. Il attire l'attention sur les relations entre la résistance à la compression simple et d'autres résultats de mesure, tels que l'indice de résistance entre pointes, la résistance à la traction brésilienne et la valeur de rebond au marteau de Schmidt. La résistance mesurée est négativement corrélée à la porosité qui est considérée comme un important indicateur de l'état d'altération.
