ABSTRACT:
A cement composition for extrusion which is produced by incorporating, into cement mortar, 3 to 15 weight % of crushed pulp fiber, 0.2 to 1 weight % of at least one member selected from an alkylcellulose and a hydroxyalkylalkyllcellulose, and a 2% water solution having a viscosity of 80,000 cps or more allows for reduced production costs by reducing the loads of the binder material using a pulp fiber without carcinogenicitic asbestos fiber. Furthermore, it allows for excellent extrudability and provides the moldings with workability such as nailing and sawing.
