Mechanical Properties of Preservative Treated Marine Piles
註釋Forty southern pine and thirty-five Douglas fir piles were destructively tested at the Forest Research Laboratory, Corvallis, Oregon. The forty southern pine piles represent eight different preservative treatments (including one lot untreated), five replicates each. One of these treatments was omitted for Douglas fir. The findings were, in general, a reduction in desirable wood characteristics stemming from preservative treatments; in particular, more reduction for dual treatment than for creosote. This, with the higher cost of dual treatments, suggests that before dual treatment can be recommended, it will require evidence of materially greater longevity for the use and environment intended.
