Abstract: The paper summarized the application of recycled expanded polystyrene (EPS) particles in concrete.Firstly,the differences between recycled EPS and original EPS were compared.The relationship between density grade and mechanical properties of recycled EPS concrete was elaborated.Other properties of EPS concrete,such as thermal performance,fire resistance performance,sound insulation and wave absorption,were introduced.Secondly,the influencing factors of recycled EPS concrete were elaborated from the aspects of EPS particle gradation and content,fiber,modifier,mineral admixture,water cement ratio.Finally,the industrial application of recycled EPS concrete was summarized,and the future research of recycled EPS concrete was prospected.The possible problems in the future research and application process were proposed.

Key words: recycled expanded polystyrene, concrete, energy saving and environmental protection, lightweight insulation
