Abstract
The effect of fire-retardant treatment and redrying on the mechanical properties of radiata pine sapwood were evaluated. Small, clear specimens were treated with three different fire-retardant(FR) chemicals, borax-boric acid(BRX), minalith(MIN), and pyresote(PYR), with target retentions of 30 and 60kg/
