Suitability of compacted and plastic soil cement prepared with sea water, for shore protection of islands in Arctic marine environment, is investigated. The laboratory test results indicate that compacted soil cement containing 16 percent Class G oil well cement and placed at maximum dry density and optimum moisture content hardens sufficiently within 24 hours to resist wave erosion in the Beaufort Sea. Plastic soil cement containing 22 percent Class G cement and 5. 5 percent fly ash developed adequate strength within 24 hours even under submerged conditions. The study also found that use of sea water in soil cement did not hinder strength development, extended soaking in sea water did not reduce the strength, and low curing temperatures did not seriously affect the 28 day compressive strength.
