The flexural strength of ice plates bonded together by freezing water (freeze-bond) is investigated in this work. Freshwater S2 columnar grained ice was used as a parent material to be bonded; water of salinities ranging from 0 to 35 ppt was used to generate bonds. Freezing occurred in air at temperatures ranging from -3 to -25 °C and under compression of about 4 kPa for periods of time varying from 0.5 to ~100 hrs. The bond strength was measured under 4-point bending. The study revealed that the flexural strength of bonded ice decreases with an increase in both salinity and temperature. The flexural strength of freshwater bonds is similar or higher than the flexural strength of intact parent material after less than 0.5 hrs freezing. The strength of the saline ice bonds levels off within ~6-12 hours of freezing.
