Chromated copper arsenate (CCA)[edit]

Perhaps even extra promising is the idea of employing treated-Wooden fiber in fiber-cement solutions, that happen to be immediately gaining in acceptance. An posting by Felton and De Groot inside the July-August 1996 difficulty in the Forest Products Journal described that using CCA-treated wood fiber in wood-Portland cement composites resulted in improved efficiency, in contrast with using untreated Wooden.

. This two-webpage guidebook specifics the prevalent preservatives used today to protect wood utility poles from decay fungi and insects, providing a long time of support lifestyle in place.

Mainly because treated wood is intended to increase the usefulness and life of wood, fewer trees are necessary to complete precisely the same purpose that is needed when untreated Wooden is utilised.
