ABSTRACT:
A hydraulic inorganic compositions which comprises a hydraulic inorganic powder at least one of polysaccharides selected from the group consisting of .beta.-1,3-glucans, pullulan and XCD-Polymer in an amount of 0.1-10 parts by weight in relation to 100 parts by weight of the hydraulic inorganic powder, and water in an effective amount.
The composition preferably further contains a reinforcing fiber, a filler, in particular mountain leather, a coagulant and/or a second molding aid, in particular, methyl cellulose.
The composition is hardened by hydration under normal pressure to provide a hardened molded article such as a cement board.
