Abstract

PURPOSE: To suppress the hindrance for the setting of cement and to increase the strength of a cemented excelsior baord, by treating the excelsior with a sulfate group-containing salt and a chloride.
CONSTITUTION: Excelsior is treated with preferably an aqueous solution of a sulfate group-containing salt, e.g. magnesium sulfate, etc., and a chloride, e.g. magnesium chloride, etc., by the dipping method, etc.. The treatment may be successive dipping in each aqueous solution of the salt and the chloride, or dipping in the aqueous solution of both salts. The preferable amount of the sulfate and the chloride are 0.5W10 wt.% and 2W6 wt.%, respectively, on the basis of cement.
