PROBLEM TO BE SOLVED: To provide an explosive fracture-resistant cement hardened body which has excellent explosive fracture resistance, whose strength designing is easily carried out, since it exhibits≥30 N/mm<SP>2</SP>practical strength, and which is hardly affected by inherent water. SOLUTION: The explosive fracture-resistant cement hardened body is formed by carbonation-treating a part or the whole of the cement hardened body and contains cement composed essentially of calcium aluminate and a method of producing the same is provided. The explosive fracture-resistant cement hardened body contains a latent hydraulic compound and/or a pozzolan compound, is adjusted to have 40-60% water/binder ratio and can contain an organic fiber having≤3 mm fiber length.
