ABSTRACT:
A novel method for producing a high-strength inorganic cement article is provided. The method comprises kneading under high shearing force a cement mixture containing as essential components hydraulic cement, a hydrophilic organic binder and water, molding the kneaded mixture into an article having a water-to-solid weight ratio of not more than about 0.2, preliminarily hydrating the molded article, firing the preliminarily hydrated article at about 300.degree. to about 1000.degree. C., and then rehydrating the fired article. The resulting cement article has bending strength of not lower than about 200 kgf/sq.cm without fibrous reinforcing materials and has that of not lower than about 350 kgf/sq.cm when reinforced with heat-resistant fiber materials. The cement article can be advantageously glazed in the above mentioned method by applying a glazing agent to a desired surface of the preliminarily hydrated article and then firing the article.
