<p>A wet-formed inorganic article comprising, on a dry basis, 0.1 to 1.5 weight % of a superfine organic synthetic fiber (A) with a size of 0.05 to 0.5 denier, 0.5 to 5 weight % of a regular-size organic synthetic fiber (B) with a size of 0.6 to 20 deniers, 0.01 to 5 weight % of an inorganic dispersing agent represented by sepiolite, a small amount of a high molecular flocking agent, and the remainder of a hydraulic material such as cement, (A) and (B) taken together accounting for 0.6 to 6.5 weight % and (A)/(B) being in the range of 0.1 to 1, has high bending and tensile strength values and sufficient toughness notwithstanding the absence of asbestos and pulp, and is economically advantageous.</p> |
