The qualify of lightweight aggregate made from waste PET bottle(WPLA) and the workability, the unit weight and strength property of concrete with WPLA were investigated for the purpose of recycling the waste PET bottles as lightweight concrete fine aggregate. This study indicated a good result that WPLA should be replaced with less than of natural fine aggregate. When WPLA was replaced with of natural fine aggregate, the specific gravity and water absorption of mixed fine aggregate were greatly reduced about 23 and respectively in comparison with those of river sand. The quality of WPLA affected on the properties of lightweight aggregate concrete. The workability of fresh concrete with WPLA(WPLAC) was improved with increasing the replacement ratio of WPLA and water cement ratio. Slump increasing ratio of the former showed about because that a specific gravity of fine aggregate was decreased from 2.6 to 1.7. The unit weight of concrete with WPLA was decreased about in comparison with that of control concrete. Furthermore, the compressive strength of concrete with 25 and WPLA at the age of 28 days increased higher than 30 MPa regardless with water cement ratio (W/C=45, 49 and ) of this study. Specific strength of concrete with WPLA, , was higher than that of contro concrete in water cement ratio of . The compressive strength-splitting tensile strength ratio and compressive strength-modulus of elasticity ratio of WPLAC were similar to that of nomal lightweight aggregate concrete. This results showed a good estimation that WPLA will be able to recycled as a fine aggregate for lightweight concrete.
