Production manner of the alumina cement constituent which features the alumina cement

摘要

PROBLEM TO BE SOLVED: To provide an alumina cement composition stable for a long term and a monolithic refractory using it.;SOLUTION: The alumina cement composition, protected from weathering and stable for a long term, is prepared by incorporating at least one water repellent selected from the group consisting of silicones, paraffins, water-soluble polymers, and fatty acids into the composition or by treating alumina cement in an atmosphere containing the vapor of the water repellent. The monolithic refractory is prepared by using the alumina cement composition.;COPYRIGHT: (C)2005,JPO&NCIPI
