Abstract : Mechanical properties were measured on small clear bending specimens of longleaf pine sapwood treated with three waterborne salt preservative systems. Preservative retentions ranged from 0.25 to 2.5 pounds per cubic foot lbs/cu ft, and specimens were either air dried or kiln dried at 140 F. Modulus of elasticity of specimens dried at this schedule was not affected by preservative salt retentions of up to 2.5 lb/cu ft. Modulus of rupture was not affected by ACA treatments regardless of type of drying; was reduced by CCA-11 at 2.5 lb/cu ft when kiln dried; and was reduced by CCA-1 at retentions above 0.25, especially when kiln dried. Work to maximum lod was adversely affected by CCA-1 and CCA-11 at nearly retentions when air dried or kiln dried and by ACA at retentions of 1.0 and 2.5 lb/cu ft.
