The cement of fly ashflaxchip board is a kind of panel bonded inorganic compound. This paper analyses by experement that the relationships are among six main manufacturing factors, ie, the ratio of flaxchip and cement with fly ash, the ratio of water and cement with fly ash, the use levels of water glass, the use levels of CaCl2, the mix levels of fly ash in cement, the density of the board, and the properties of the board. It is possible that the panel bonded inorganic compound can be produced by the cement with fly ash and flaxchip as material so long as the suitable preparing conditions are taken up.
