Chinese fir has some major drawbacks, such as loose structure, light and soft, low strength, etc. Impregna- tion modification is an important method to improve its properties. However, the traditional organic resin impregnation modification had the serious problems of releasing toxic gas, inflammable, etc. In view of this, the mechanical prop- erties, dimensional stability, fire resistance and smoke suppression of Chinese fir can be significantly improved by im- pregnation of inorganic materials, which can convert low grade Chinese fir into the...
