Analysis of Dispersivity in Marine Clays of Cartagena de Indias, Colombia

This study assessed the dispersivity of soils extracted from northern region Cartagena de Indias (Colombia) using pinhole test, crumb and chemical–microstructural analyses. Dispersive are susceptible to erosive phenomena upon contact with water, yet they have not been adequately characterized in city. To evaluate degree different deformed undisturbed soil samples, characterization tests included particle size analysis, chemical composition, Atterberg limits, specific gravity, compaction. The results showed that highly plastic clays (i.e., CH) a slight moderate level ND3) according test confirmed by test. sample sodium levels ranged 0.72% 1.94%, had an optimal moisture content 26% maximum apparent dry unit weight 13.87 kN/m3. According standards results, Indias’s studied marine unsuitable for civil construction due uncertainty their behavior.
