The physical-mechanical characterization of the aggregates from the Jiu River as a depending function on the relationships between them

Abstract

In the Jiu River Basin, the geography, geology and climate have an important role in the decomposition of surface rocks, fragmentizing them and then transporting them from their place of origin. Water in its various forms and even the air in motion, are destructive forces in open areas and rugged terrain, causing the main processes by which rocks disintegrate. Rock's fragmentation is the outcome of the loss of cohesion of mineral aggregates under the influence of external factors. Disintegration's speed and intensity depend on the petrographic nature of the underlying rocks as well as on their position in relation to climate and terrain factors. The purpose of this paper is to present experimental data obtained in laboratory from analysis on different sorts of aggregates collected from five gravel pits (Sadu Valley, Iezureni, Dragutesti, Sardanesti and Ionesti) placed on the Jiu River and establish the correlations between the physical and mechanical characteristics. © SGEM2012 All Rights Reserved by the International Multidisciplinary Scientific GeoConference SGEM.
