Abstract

An experimental work on replacing recycle pet bottles with sand in concrete in this paper. 5, 10, and 15% Pet equivalent with sand in concrete including 4 different mixes with constant water to cement ratio and totally 96 specimens was used and made; compressive strengths of cubic and cylinder specimens, tensile split strength of cylinder specimens, impact strengths plus flexural strengths of reinforced and plain concrete slabs were obtained. The results indicated that the workability of fresh concrete was decreased up to 50% by increasing the pet percentage up to 15% but the compressive and tensile strengths of hard concrete were decreased up to 18 and 21%. And also the flexural strengths and impact strength (initial and final cracks) were increased up to 13 and 19% due to increasing recycle pet percentage
