Abstract
Relationships between the static and the dynamic moduli of elasticity are presented for a range of cement stabilised materials and discussed in relation to published data for materials of this type and for concrete.
The relationships are basically empirical but an attempt is made to allow for density and for strengths in tension and in compression.
Résumé
L'article traite des relations entre les modules d'élasticité statiques et dynamiques (résonance) pour une gamme de matériaux stabilisés au ciment. Ces relations sont discutées en rapport avec les informations publiées.
La conclusion principale est que les modules statiques et dynamiques d'une gamme de matériaux stabilisés au ciment sont en assez bonne corrélation pour qu'une estimation satisfaisante de la valeur statique en vue d'une utilisation pratique soit obtenue en déduisant 5 GN/m2 de la valeur dynamique pour des modules plus grands que 15 GN/m2.
On propose des équations entre les modules statiques et dynamiques qui prennent en considération la densité des éprouvettes, ainsi que d'autres équations où sont considérées la résistance et la densité ensemble. Ces relations empiriques sont valables seulement pour les matériaux: gamme de résistances et valeurs des modules, étudiés dans cette recherche.
