The purpose of this study is to develop an effective recycling method for waste expanded polystyrene (EPS). Polymer mortars using the binders based on a styrene solution of the waste expanded polystyrene are prepared with various binder contents, crosslinking agent contents and coupling agent contents, and tested for consistency, working life and mechanical properties. As a result, the workability of the mortars are improved with increasing binder content and crosslinking agent content, and their working life is shorten with an increase in the crosslinking agent content. Their flexural and compressive strengths depend on the crosslinking agent content and coupling agent content, and their modulus of elasticity is greatly affected by the binder content. In general, the mechanical properties of heat-cured mortars aremuch higher than those of dry-cured mortars.
