Abstract
Los estratos de arena son utilizados con frecuencia como mantos de fundación para diferentes tipos de estructuras. En la
Ciudad de Córdoba, los limos de origen predominantemente eólico y las arenas aluviales son suelos frecuentes en los perfiles
geotécnicos.
El comportamiento de los suelos de granos gruesos, como las arenas, se encuentra influenciado por la morfología y
distribución de tamaños de granos, manifestado por la interacción entre las partículas. Este trabajo presenta una
caracterización de algunas arenas de la Ciudad de Córdoba. En el análisis se consideraron zonas de gran desarrollo urbano,
y se conformaron grupos con características similares, los grupos se denominaron: General Paz, Centro, Colorada y Ayacucho.
En laboratorio se efectuaron ensayos granulométricos y clasificación de suelos, junto con un análisis morfológico de
partículas por medio de micrografías.
The sand layers are often used as foundation beds for different types of structures. In Córdoba city, predominantly wind origin silts and alluvial sands are common soils in geotechnical profiles. The soil behavior, particularly coarse-grained soils like sands, is strongly influenced by the particles morphology and grain sizes distribution, expressed by the interaction between the particles. This paper presents a characterization of some sands from Córdoba City. The analysis considered highly developed urban areas and groups with similar characteristics were formed, the groups were designated: General Paz, Central, Colorada and Ayacucho. In laboratory tests for classification and grain sizes distribution were conducted, together with a morphological analysis of particles by micrographs.
