Objective: To find the property of a concrete mixture where conventional coarse and fine aggregate has been replace with PET granules at various ratios and test its suitability in real word scenario by various testing methods. Method: Test sample 108 in numbers were made and were tested at duration of 7 and 28 days. Also these samples had different replacement level so that optimum replacement ratio could be obtained. Various testing methods like compressive test, split tensile test and flexural test were performed to obtain statistical properties and characteristics of the concrete. Finding: It has been found that at replacement ratio of 10%, the compressive strength obtained was maximum. The optimum ratio for flexural test and split tensile test is also 10%. At this ratio the property of PET concrete is better than or equal to conventional concrete. Application: Around 335 million tons of plastic is produce annually worldwide of which 85% is not recycled. It can be used in concrete making to solve the problem of pollution and can help in saving natural resource. Also further study can focus on usability of light weight concrete in loose soil and in earthquake zone.
