Conceptual Study of Production Technology of Free-Form Concrete Segments

Free-form designs are increasing which is beyond a simple design form to meet the requirements of clients wishing to improve the building value and of the government for symbolic buildings. Furthermore, development of construction technologies, materials and equipment has led to production and installation of free-form concrete. However, unlike the fixed form, free-form concrete requires more time and manpower. In particular, mold for production of free-form materials can be used only once, which implies that excessive resources are input for mold manufacturing. This may result in reduced productivity, increased cost and extended construction duration. It is necessary to develop technologies that can solve the limitation in relation to cost, time, quality and safety so as to ensure economic feasibility and constructability of the free-form buildings. In this regard, the study intends to analyze the problems of producing free-form concrete and construction using such concrete, and to conduct a conceptual study on the technology that is capable of solving the problems. The study draws the requirements of production technology of free-form concrete, and proposes the production technology that can solve the existing problems.
