Influencia de la adición de aceite sulfonado en la respuesta dinámica a pequeñas deformaciones de un material granular arcilloso

Abstract

In this investigation, the effect of the variation of sulfonated oil over time on the dynamic properties, shear modulus and damping of a granular material with the presence of clay from the Mondoñedo sector west of the city of Bogotá was studied , using the resonant column assay. In total, 19 specified 50 mm diameter per 100 mm height were manufactured, made by adding sulfonated oil to the mixing water in proportion of 2%, compacted by the specified static method constant volume variable pressure and tested under isotropic stresses of confinement variables between 0 and 400 KPa, with cyclic torques between 0.0115 to 0.23 Nm and cure times from 0 to 90 days.
