EXTRUDABLE CEMENTITIOUS MATERIAL

摘要

A method and agent for treating a cementitious material for extrusion, comprising adding to the cementitious material a viscosity enhancing agent a nd a dispersion agent in a quantity sufficient to increase the efficacy of the viscosity enhancing agent. By increasing the efficacy of the viscosity enhancing agent, extrudability may be maintained with less viscosity enhanci ng agent or a lower grade (cheaper) viscosity enhancing agent than is conventionally used, or the extrudability may be improved for the same quantity of viscosity enhancing agent compared to a conventional dosage.
