Abstract: A laboratory study was conducted to investigate the effects of cedar oil and silica gel treatment on dimensional stability and mechanical performance of southern yellow pine (SYP) boards. Two hundred pieces of SYP and 100 pieces of red oak boards with a nominal dimension of 1 by 6 by 48 in. (25 by 152 by 1,219 mm) were selected for this study. The red oak boards were included as a standard ammunition pallet stock for comparison. The experimental procedure involved stress wave E-rating, grouping, defect mapping, preservative treatment, high-temperature kiln exposure (simulating hot and dry service condition), and flatwise static bending test. Cedar oil and silica gel treatment had a positive effect on dimensional stability of the No. 2 SYP boards, as indicated by reduced visible end-splits and board warp. Our results also indicated that cedar oil and silica gel treatment had a detrimental effect on stiffness and strength of the No. 2 SYP boards. Both modulus of elasticity and modulus of rupture decreased significantly in treated SYP compared with those of untreated SYP.

Keywords: End split; pallet deck boards; stiffness; strength; warp; work to maximum load
