Polyethylene terephthalate containers (PET bottles) are recycled into fibers and sheets, but the complicated process requires a high level of technology and large cost resulting in a low recycling rate of PET. Weight reduction of concrete has been demanded for certain uses. In view of this, lightweight concrete embedding raw PET bottles is conceivable. It may be used for void slabs and lightweight wall panels for dwelling units. Also such bottles filled with functional materials can add a new function to concrete. In this study, the basic physical properties of lightweight multifunctional concrete embedding used PET bottles were investigated. A method of placing concrete with embedded PET bottles was examined. PET bottles fixed to the mold at their caps withstood the impact and the pressure during concrete placing with no deformation and the filling capability of concrete was confirmed. The weight reduction of the reinforcing concrete panel embedding PET bottles was approximately 16%. The strength properties of concrete embedding PET bottles were examined and the compressive strength of the specimen embedding bottles with the smallest intervals between bottles was 55% of that of the solid concrete specimen.
