Summary:PROBLEM TO BE SOLVED: To provide a method for manufacturing a cement concrete cured body which is infiltrated with a drying shrinkage reducing agent, which shrinks less on drying, has high bend and crack strength, and has high crack resistance. SOLUTION: The method for manufacturing a cement concrete cured body comprises preparing a cement concrete by kneading the cement composition containing cement with water, molding the cement concrete cured body using thereof, immersing in a drying shrinkage reducing agent after mold separation, in which the infiltration depth of the drying shrinkage reducing agent is 0.5-5 mm from the surface of the cement concrete cured body, a cement composition which is composed of 80-97 parts cement and 20-3 parts expanding material based on 100 parts cement composition comprising the cement and the expanding material, which has the ratio of water/cement composition is 45-61%, and which is further coated with a waterproofing agent or water repelling agent, and which has the immersing time in the drying shrinkage reducing agent being within 3 days.
