Exterior tile setting can be divided into two types: post-bonding method, and pre-bonding method. Pre-bonding method. In pre-bonding method, different from the post-bonding method, the process of background mortaring is eliminated, saving cost of materials, work hour, and labor expenses, and it doesn’t require time for curing. It is proved that pre-bonding method of manufactured PC tile is economical in terms of Life Cycle Cost, because it method is high in stability and reduces a term of work, and cost low in maintaining and repairing. There are many problems in applying pre-bonding method to real construction work, including the efflux of cement pastes during the process of vibration tampering, and the falling off or breaking of PC tile caused by the contact of vibrator, the cost increase that results from manufacturing overly strength-revealing concrete regardless of the strength of concrete used in the manufacturing of PC cotton wall. The purpose of this study, therefore, is to present ways to resolve above problems by using fluidized concrete in PC manufacturing, and, to find out an appropriate mixture of high fluidized concrete used for PC manufacturing, targeting 280kgf/cm² of specified concrete strength by conducting fundamental experiments, and to provide basic data for bringing pre-bonding method of high fluidized concrete tile into practical use. For this purpose, this study compares adhesive strengh between tiles attached on mock experimental structure, with different mixture rate and curing method, and review and compares marginal concrete deformation rate with the drying shrinkage of concrete by imposing vertical compressive loading until the falling-off of concrete
