To provide a cemental molded body capable of building a bonded structure having a large strength (in particular, resistance to tensile force) by a simple operation in short working hours without having need to perform an operation of directly connecting reinforcing bars to each other in the cemental molded body to each other.
A cemental molded body comprises: a bond part 3 for bond to another cemental molded body via a fitting structure; and a body part 4 other than the bond part 3. The cemental molded body is made of a hardened body of a cement composition in which a region including at least the boundary between the bond part 3 and the body part 4 has a compressive strength of ≥100 N/mm2, and the cemental molded body is not broken even if a tensile force per unit width equal to or larger than 30% of the product of a cross-sectional area of the body part 4 per unit width at the boundary between the bond part 3 and the body part 4 and a tensile strength of the hardened body of the cement composition is applied to the bond part 3.
