Durability of treated and non treated woods in field test

Abstract

The durability of fence posts of Eucalyptus saligna, Eucalyptus grandis, Pinus elliottii, and Sclerolobium paniculatum treated and non treated was evaluated after 10 years in field test. The samples were submited to pressure method and non pressure methods using CCA, creosote, creosote mixture with oil and FCAP respectively. S. paniculatum were the most resistant and P. elliottii were the least resistant against fungi and termite attack between non treated samples. E. saligna were the most resistant and P. elliottii were the least resistant against fungi and termite attack, between non pressure methods showing the highest level of chemical retention treated by BQF. P. elliottii, E. grandis and S. paniculatum showed the best durability between the pressure methods with P. elliottii showing the highest level of CCA retention.
