To provide a centrifugally molded ultrahigh strength concrete composition from which a concrete molded article having high thickness precision is obtained and a producing method thereof.

The centrifugally molded ultrahigh strength concrete composition comprises a binder containing at least cement, fine aggregate, coarse aggregate and water, wherein the ratio of water to the binder is 20% and the unit quantity of water is 100-120 kg/m3. Because the quantity of coarse aggregate G is increased, the formation of a mortar layer 2 is suppressed to improve the thickness precision.
