CEMENT MORTAR ADDITIVE FOR EXTRUSION MOLDING, AND CEMENT MORTAR FOR EXTRUSION MOLDING HAVING THE ADDITIVE

摘要

PURPOSE: A cement mortar additive for extrusion molding, and cement mortar for extrusion molding containing thereof are provided to secure the excellent extrusion capacity by containing two different surfactants with different electrical properties. CONSTITUTION: A cement mortar additive for extrusion molding contains two different surfactants with different electrical properties, and a cellulose derivative. The surfactants include an anionic surfactant, and a nonionic copolymeric surfactant. The content ratio of the anionic surfactant and the nonionic copolymeric surfactant is 1:99~99:1. 0.001~20 parts of surfactants by weight is mixed with 100 parts of cellulose ether by weight.
