PROBLEM TO BE SOLVED: To provide hardening promoting actions of a cement-based material for extrusion molding, shorten the curing time and obtain a cement-based extrusion molding product without any problems in extrusion molding. ;SOLUTION: This admixture for a cement-based material for extrusion molding comprises a water-soluble cellulosic ether capable of manifesting setting retarding actions on a cement and calcium chloride at (99.5-80):(0.5-20) respective weight compositional ratio. The admixture is used by adding 0.2-2 pts.wt. based on 100 pts.wt. cement-based material for extrusion molding thereto.;COPYRIGHT: (C)1997,JPO
