Durability of Pinus elliottii Wood Impregnated with Quebracho Colorado (Schinopsis balansae) Bio-Protectives Extracts and CCA

Some wood preservatives have a warning due to environmental restrictions and risks to man health. The aim of this study is to determine the performance of non impregnated and impregnated wood with a CCA salt and a bio-protective made from "quebracho colorado", when facing the action of fun...
