摘要：
A highly fire resistant construction board is produced by embedding a sheet of expanded metal net in a building board made from a water settable inorganic binder. In a preferred embodiment, the wallboard is made from a combination of gypsum, cement, and a particulate mineral filler such as perlite or vermiculite, and contains an embedded layer of expanded metal net made from a magnesium alloy.
