PURPOSE:To provide cement composition for honeycomb molding, capable of uniformly curing molded products and a sufficiently maintaining the shape retainability of the molded products after molded, even when a cellulose ether binder is used in a reduced amount, on the extrusion molding of the honeycomb having a wall thickness of <=1mm and a cell hole diameter of approximately <=5mm from the powder of a cement. CONSTITUTION:The cement composition for the honeycomb molding comprises 2-5 pts.wt. of a water-soluble cellulose ether added to 100 pts.wt. of a cement, the 2% aqueous solution of the water-soluble cellulose ether having a viscosity of >=80000 cP as measured with an Ubbellohde viscometer No.5 according to JIS K-2263 at 20 deg.C. |
