摘要： PROBLEM TO BE SOLVED: To economically and efficiently obtain a segment forming neither air pock mark nor water pock mark, by placing a concrete having high fluidity in a closed type frame mold, rapidly curing the concrete with steam at a specific temperature, removing the frame mold after a fixed time and finishing the surface of the concrete by a trowel.
SOLUTION: A concrete 5 having high fluidity is placed in a frame mold 3 for producing a closed type segment, equipped with a main body frame mold 1 and a cover frame mold 2. The concrete 5 having high fluidity has, for example, fluidity of about 30% water powder ratio, about 60±5 cm, slump flow value and about 4.5% air amount and high self filling and does not require vibration fastening causing noise and vibration. Immediately after the placing of the concrete, the concrete is cured with steam in an atmosphere at 30-50°C and the hardening of the concrete 5 is mildly promoted. The cover frame mold 2 is removed 2 to 4 hours after the placing and the surface of the concrete 5 capable of retaining the shape is finished by a trowel to smooth the unevenness. Then the concrete 5 is continuously cured with steam for a fixed time, is hardened and removed from the main body frame mold 1.
