Geotechnical Characterization Of A Soil Of Tropical Origin: Physical, Chemical, Microstructural, Mechanical And Compressive Properties
Jair Arrieta , Carlos Millan and Fernando Jove
Abstract
Due to the urban expansion of large cities, the characterization of the soils that are being used for civil construction is very significant: roads, bridges, and buildings. For this reason, in this study, soil from the Guabirotuba formation in Brazil is physically and mechanically characterized. The results show that it is predominantly silty soil but contains clay minerals that make it expansive. In addition, its geological origin shows it is in a normally consolidated state. Finally, the resistance of the soil in its natural and compacted state shows values below 500 kPa, which makes it a soil with low mechanical resistance, but which could be improved with chemical stabilization and geopolymerization techniques.
