PROBLEM TO BE SOLVED: To provide a cement composition for centrifugal force molding capable of greatly reducing the amount of slag discharged without reducing the strength of both the slump of the cement composition and the obtained concrete or mortar. A method for producing a product, and a centrifugal molded product. A method for producing a cement composition containing the following A component, B component, cement, water and fine aggregate, or additionally a coarse aggregate, comprising A component, cement, water and fine aggregate, Or after further kneading the coarse aggregate, The B component was added and kneaded, and the yield value of the cement composition = (0. 85-1.15) × (yield value of reference cement composition), plastic viscosity of cement composition = (1.5-5.0) × (plastic viscosity of reference cement composition) And a centrifugal molded product obtained by centrifugally molding the cement composition. A component: water reducing agent and / or high performance water reducing agent, B component: Thickener |
