Abstract

PURPOSE: To cement fibrous materials, e.g. a construction board, with a high operating efficiency, by using a magnesia cement having a specific surface area comprising MgO-MgSO4-H2O.
CONSTITUTION: Fibrous material, e.g. a construction boards, are cemented by hardening a magnesia cement having a specific surface area of 20W50m2/g comprising reactive magnesia (MgO-MgSO4-H2O) through heat generation. The cement can be obtained by mixing 20W50wt% of reactive magnesia with an aqueous magne sium sulfate.
