Effect of post-treatment drying schedule on the modulus of elasticity of CCA-treated southern pine dimension stock using nondestructive methods

IRG/WP 3413

H M Barnes, S Moore

This paper describes the results from the nondestructive testing for modulus of elasticity (MOE) of southern pine (Pinus sp.) 2 x 6's treated with chromated copper arsenate and redried using three commercial kiln schedules. The data indicate that redrying CCA-treated southern pine dimension stock treated to above-ground retentions (4 kg/m³) has no deleterious effect on the MOE, regardless of the kiln schedule employed. These data tend to confirm conclusions of other work with redrying of treated pine which indicate that MOE is not affected by the redrying schedule.
