Mechanical and mineralogical characteristics of mortars with crushed and river sand
The aim of this study is to characterize the mixtures of crushed sand and river sand for an optimal use in the formulation of mortars and concretes. Physical, chemical and mineralogical characterization of aggregates was done, followed by the formulation of mortars by substituting 100%, 50% and 0% of river sand by crushed sand. The compressive stre...
Plaine alluviale du Niger supérieur et mare de Baro (Guinée) : fonctionnement hydrologique, gestion traditionnelle des r...
Si la mare de Baro est célèbre pour sa pêche annuelle rituelle, en revanche son fonctionnement hydrologique demeurait inconnu jusqu’à la mise en place d’un référentiel altimétrique pour le plan d’eau et la plaine alentour, mis en relation avec les hauteurs d’eau du Niandan. Les processus d’alimentation sont désormais cernés et une modélisation perm...
Origin and evolution of Ngaye river alluvial sediments, Northern Cameroon : geochemical contraints
The origin of Ngaye River alluvial sediments and the evaluation of the weathering degree of their source rocks are assessed using trace and rare-earth element geochemistry in three bulk sediments and their different size fractions (2000–200 lm, 200–50 lm, 50–2 lm and

Undrained behaviour of the sandy-silty level of the Tiber river alluvial deposits in Rome (Italy)
This paper reports the findings from a laboratory study aimed at the physical and mechanical characterisation of sands belonging to recent Tiber river alluvia (level D Auct.) located in historical centre of Rome. The study was conducted in preparation for subsequent analysis of possible seismically-induced effects of permanent deformation and/or li...
