Abstract

This work presents a study to characterize the aggregates through their geometrical properties (size, shape and size distribution), mechanical (uniaxial compressive strength and modulus of elasticity), physical (porosity, water absorption) and finally chemical and mineralogical properties. The relationships between Young's modulus and uniaxial compressive strength of rocks from the Haute Garonne, France, were investigated. The relationships between these properties are described by simple regression analyzes. The results indicate an excellent correlation obtained between the modulus of elasticity and uniaxial compressive strength. Additionally, the limestone presents nevertheless differences between the measured values appreciably less important. This dispersion can be correlated with the variations of the mineralogical nature of the aggregates within the same career and also with the quality of their structures and textures.
