In order to explore the mechanical properties of hollow blocks doped with polystyrene particles un-der various conditions,standard hollow blocks were made according to different mix ratios,the density is mea-sured,the material strength is tested,the compressive strength is analyzed,and the thermal insulation proper-ties of hollow blocks are explored.It is considered that when the substitution rate of recycled fine aggregate,coarse aggregate and polystyrene particles is 50%,100%and 15%respectively,the material can ensure the structural strength on the basis of satisfying the thermal insulation performance.
