The technology of making fly-ash particleboard has been developedwith fly-ash from two different power plants.The results showed: ①The Quan-tity and kinds of additives should be different depending on the chemical com-positons and the quality of different fly-ashes.②The ratio of fly-ash and woodparticle was the most outstanding factor which affected the mechanical and phys-ical properties of fly-ash particleboard.③The density was a very notable factoraffecting the properties of fly-ash particleboard and it should not be lowerthan 0.90g/cm￣3.④Increasing the resin content could improve the MOR of fly-ash particleboard,but the effect was not remarkable when resin content was biggerthan 9%.Brief information on the productive experiment, primary economical analysisand prospect of the market of fly-ash particleboard was also introduced in the article.
