Pilotscale modeling of colloidal silica delivery to

Feb 01, 2015nbsp018332Conlee 2010 conducted a series of CS silica field injection tests to treat a 0.5-m-thick layer of poorly graded sand with silt against liquefaction. The injection was performed in a 9 m 2 area with an average injection rate of 5.7 lmin. Following the treatment, some dynamic shaking was introduced with dynamic shaker TRex. The induced accelerations ranged from 0.05 g to 0.4 g.
