Abstract
The present invention provides a concrete composition having a heat resisting property and dimensional stability, which comprises a cement selected from the group consisting of a self-hardening cement, a latent hydraulic material, a mixed cement and a thermosetting cement, a hydraulic material, an aggregate, a carbonaceous material acting as a binder and selected from the group consisting of a powdered coke and pitch coke, and potassium titanate whisker. Since the concrete composition of the invention is resistant to firing and can be used at a high temperature, a solidified mass prepared therefrom can be applied with a glaze and heated to have an enamelled surface.

A concrete composition having a heat resisting property and dimensional stability, comprising a cement selected from the group consisting of a self-hardening cement, a latent hydraulic cement and a thermosetting cement, a hydraulic material, an aggregate, a carbonaceous material selected from the group consisting of a powdered coke and a pitch coke, said carbonaceous material capable of forming mesophase spherical particles by heating and being added in a ratio range of from about 0.1:1 to about 1:1 by weight of carbonaceous material to cement, and potassium titanate whisker having a diameter of about 0.1 to 1.0 micrometer and a length of 0.1 to 0.2 mm which is added at ratio range of from about 0.05:1 to about 0.5:1 by weight of whisker to cement.
A concrete composition having heat resisting property and dimensional stability comprising carbonaceous material and potassium titanate whiskers in a polymer dispersion added to a kneaded mixture of an aggregate, a hydraulic material, and a cement selected from the group consisting of a self-hardening cement, a latent hydraulic cement and a thermosetting cement, said carbonaceous material capable of forming mesophase sperical particles by heating and being added in a ratio range of from about 0.1:1 to about 1:1 by weight of carbonaceous material to cement, and potassium titanate whisker having a diameter of about 0.1 to 1.0 micrometer and a length of 0.1 to 0.2 mm which is added at a ratio range of from about 0.05:1 to about 0.5:1 by weight of whisker to cement.
