A concrete filled steel tube column. The concrete filled steel tube column includes a steel tube having an inner face; a concrete core disposed within the steel tube; and a separating layer interposed between the inner face of the steel tube and the concrete core for separating the concrete core from the inner face of the steel tube so that the steel tube may not be bonded to the concrete core. After the separating layer is formed on the inner face of the steel tube, the concrete is charged into the steel tube to form a concrete core.

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.
