Abstract
(Part of Innovations in Grouting and Soil Improvement - GSP 136) Mitigation of liquefaction potential in granular soil can theoretically be achieved through permeation of colloidal silica. However, practical application of this technique requires an efficient and adequate delivery of the silica. The purpose of this research is to evaluate colloidal silica transport mechanisms. The work consisted of short (0.9 m) column tests to identify the variables that influence stabilizer transport through soil formations. It was found that the primary variable influencing transport is the viscosity of the stabilizer solution. The results show that colloidal silica stabilizer can be delivered to the soil column in an adequate concentration to stabilize the soil. Unconfined compression tests on the treated specimens indicate that treatment with 5 weight percent colloidal silica provides adequate strength for mitigation of liquefaction risk.
