Preliminary studies undertaken to assess the feasibility of utilizing gravity structures on soft arctic silts indicate that the available foundation capacity are insufficient. Therefore prior to site utilization, substantial soil strengthening will be required. At the present time, there is only limited information concerning strengthening of arctic silts. This paper presents the results of a two-phase laboratory program performed to evaluate the feasibility of strengthening arctic silts using Portland Cement.
