Abstract：This work examined the influence of the aggregate shape and dosage of plate and cylindrical waste plastic film on mortar fluidity,flexural strength,compressive strength,deflection and fracture toughness,with waste plastic film aggregate replacing the sand in mortar. The results show that the deflection of mortar increases with the content of the plastic aggregate( sheet or cylinder). The properties of fluidity,flexural strength,compressive strength and fracture toughness decline with the increase of sheet plastic aggregate content. However,the fluidity increases,and the compressive strength decreases,with the increase of cylinder plastic aggregate. The flexural strength of mortar has no distinct change at a low content of cylinder plastic aggregate.The fracture toughness increases at a low content of cylinder plastic aggregate and decreases at a higher content.
