percent) and three temperatures (20°C, 0°C, and -40°C) were tested in four-point bending until failure.Temperature was observed to affect the failure mechanism of the beams, with the beams tested at 0°C and 20°C failing in shear and the beams tested at -40°C failing in tension. Further, the strengths of the beams and their stiffnesses were observed to increase with decreasing temperature, with these effects being more pronounced in the higher moisture content beams. Over the temperature range of 20°C to -40°C, the 12 percent moisture content beams observed strength and stiffness gains of 17 and 22 percent, while the 28 percent moisture content beams observed respective gains of 37 percent and 66 percent.
