Thermal conductivities of 20-30 and 30-100 Ottawa sand compacted with 30-100 crushed ice were measured by probe method of transient heating; commercially available probe 0.02 in. in diam with length/diam ratio of 412 was used; temperatures were 18 and 23 F; water contents ranged from air-dry to 100% by weight; as percentage of ice was increased, thermal conductivity increased from value for air-dry sand to value for bulk ice; thermal conductivity at 23 F was higher than at 18 F.
