Abstract
As evidence by recent structural problems with fire retardant treated plywood, fire retardant chemicals and high temperature environments can degrade the strength properties of wood. We do not know to what extent fire retardant chemicals, thermal environments, and moisture content contribute to wood degradation. We suspect that the combination of acidic fire retardant cheicals and elevated temperatures increases the rate of acid hydrolsis in the wood, thereby causing a loss in strength. This paper presents a review of the pertinent literature on the factors influencing stregth reduction in treated woods.
