In this research Concrete mix designs were prepared according to the DOE method and a total of 6 mixes with 72 samples prepared to consist of concrete grade C-25.The test samples were produced with the percentage of substitution for the fine aggregate by 1, 2, 3, 4, and 5% of PET plastic waste aggregate.Moreover, a control mix without replacement for the fine aggregate was used to have a relative analysis.The prepared samples consist of concrete cubes, cylinders, and beams.Furthermore, laboratory experiments were carried out for the prepared concrete test samples.
The lists of experiments conducted were; material property, slump, unit weight, compressive strength, splitting 6 Piece Reclining Sectional tensile strength, and flexural strength tests.The test results were analyzed and compared with the respective conventional concrete characteristics and show that there was a slight increase in compressive strength of the concrete up to 3% replacement and reduction in compressive strength increases beyond 3% replacement due to the replacement of PET aggregates.Also like compressive strength there was an increase of tensile strength Serum recorded with increasing PET bottle aggregate content up to 3% replacement.But more than 3% substitution of fine aggregate with PET bottle fiber results in a reduction in tensile strength, flexural strength.This test result shows that as it is possible to use PET bottles in concrete production as a partial substitution for fine aggregates not more than 3% replacement.
