Admixture and extrudable hydraulic composition

摘要

An admixture comprising a nonionic water-soluble cellulose ether having a transparency of 35-89% in a 2 wt% aqueous solution at 20 DEG C is suited for hydraulic compositions. The hydraulic composition comprising the admixture and a less amount of pulp fibers is extrudable into a hardened part having a satisfactory flexural strength and surface smoothness.
