wood preservation measures, there are a number of different (chemical) preservatives and processes (also known as timber treatment, lumber treatment or pressure treatment) that can extend the life of wood, timber, wood structures or engineered wood. These generally increase the durability and resistance from being 

Pressure-treated lumber is highly resistant to decay and insects. Through a series of pressure and vacuum cycles, wood preservative is forced deep into wood pores, forming a chemical barrier against termites and decay. Many people are familiar with green Chromated Copper Arsenate (CCA) treated wood. It has been 

Addition of low levels of acid (0.025-0.1% w/w HC1) improved performance against basidiomycetes, and to a lesser extent soft-rot fungi. Addition of high levels of acid (1% w/w HC1) further improved soft-rot control, but resistance of treated wood to basidiomycete attack was reduced. Addition of alkali to treating solutions.

Common chemical treatments include copper azole and alkaline copper quaternary (abbreviated as CA and ACQ, respectively), which have taken the place of chromated . Pros: Nontoxic; noncorrosive to fasteners; long warranties; more stable than chemically treated wood; resistant to insects and fungi.

He suggested that the industry take the same approach his father and grandfather took: Stop treating wood for above-ground use and treat all wood—posts, dimensional framing lumber, and decking included—for ground contact. While that idea didn't fly with the committee, they did agree to form a task 

They turned first to water-based alkaline copper quaternary (ACQ) and copper azole (CA), both of which had been used for many years to treat wood in To protect the wood, both ACQ and CA — like CCA — depend on copper and a co-biocide, which is a chemical added to the formula to kill organisms

sive–wood interface of bonded products. Wood hemicelluloses are susceptible to both acid and alkali degradation. Generally, cellulose is more resistant to alkali and lignin is more resistant to acids (Sjostrom 1993). Adhesive standards often specify a maximum or minimum adhesive pH as characterized by mea- surement
