COMPOSITION FOR HARDENED MATERIAL, INORGANIC HARDENED MATERIAL, AND HARDENED MATERIAL HARDENED BY CARBONATION

摘要

PROBLEM TO BE SOLVED: To provide a composition for a hardened material, which is suitably used for obtaining a moisture control material having high moisture absorption-desorption performance, capable of being prepared by short time curing treatment, and excellent in mechanical physical properties and structure stability; and to provide an inorganic hardened material and a hardened material hardened by carbonation.;SOLUTION: The composition for the hardened material is characterized in that a hydrous magnesium silicate mineral (preferably, the median diameter is 5-50 m, and the content is 30-80 wt.%), obtained by firing attapulgite and/or sepiolite at 150-800C, and a gas-hardenable material and/or a hydraulic material (preferably, the material is calcium silicate having an aspect ratio of 10-25) are contained (further preferably, a pulp fiber having a degree of beating of 50-200 is blended in an amount of 2-10 wt.%). The inorganic hardened material and the hardened material hardened by carbonation are each derived from the composition for the hardened material.;COPYRIGHT: (C)2004,JPO&NCIPI
