AbstractFour different platen configurations were used to determine the influence of some end conditions on the laboratory- determined uniaxial compressive strength of frozen sand. Cylindrical specimens of fine Ottawa sand (ASTM designation C-109), compacted at the optimum moisture content and saturated before unidirectional freezing, were tested at temperatures varying between -5 and -6 degrees C. Each specimen was subjected to a constant strain rate of 0.7 x 10[-3] min[-1] using an Instron, universal testing machine ( model 1127). A compliant platen designed to reduce friction between platen and specimen, to distribute the load uniformly, and to minimize stress gradients produced by eccentric loading, was found to be most desirable in determining the uniaxial compressive strength of the frozen sand specimens.
