The values of shear strength of the ice rubble in the ridge keels and rubble fields are important in force computations. To increase the data on ridge properties, the shear strength of partially consolidated ice rubble was studied by making tests in a shear box. The only variable was the consolidation time. The tests were done in a simple shear box in which the top and bottom of the ice are not confined. The dimensions of the box were 0.96 m in length, 0.8 m in width and 0.8 m in height. The upper part of the box was pulled with the carriage. The ice field was sawn in blocks in order to get a controlled block size distribution. The size distribution for the ice blocks was selected to correspond published data on full-scale ice ridges. The measured mean values of shear strength varied from 1 kPa to 17 kPa depending on the freezing conditions.
