Precast composite concrete combines half-precast members manufactured in a factory with concrete placed at the construction site. The method of construction using precast composite concrete is characterized by stable quality ensured by the use of half precast members, continuity provided by the cast-in-place concrete, reduction of the environmental burden through decreased use of sheathing, rationalization of construction, and labor saving. On the other hand, points to keep in mind regarding the introduction of this construction method is that it requires a detailed construction plan, appropriate work procedures and methods, and careful quality control. All the above is covered in Recommendations for Construction Practice of Reinforced Concrete with Half Precast Concrete Members of the Architectural Institute of Japan. The Recommendations were revised in October 2019, and this paper presents an outline of the revised edition.
