DENSIFIED RADIATA PINE FOR STRUCTURAL COMPOSITES

Maderas: Ciencia y Tecnología, 2006
A novel wood-based composite has been developed for use in structural applications. The process was designed to utilize rapidly-grown, low density, wood species. Plantation grown radiata pine is particularly well suited to this process.

RADIATA PINE pH AND BUFFERING CAPACITY: EFFECT OF AGE AND LOCATION IN THE STEM

Maderas: Ciencia y Tecnología, 2013
In this work the effect of age and location within the stem on pH and buffering capacity of radiata pine sapwood was investigated. Mature and juvenile wood samples from three different heights in the trunk were obtained from 20, 25, and 30 year-old trees.
