An Experimental Investigation on Partial Replacement of Fine Aggregate by Polyethylene Terephthalate

Ecological concerns emerging from over digging of natural sand have prompted different limitations on its extraction. Uncontrolled mining action compounds the circumstance. Consequently genuine mindfulness has been mulled over, must be distinguished as a potential river sand substitution for fine aggregate substitution in concrete. For this audit, using reused material is portrayed as a fine aggregate substitution to natural sand, especially reused Polyethylene Terephthalate (PET). The main objective of this research was to explore the feasibility of using PET as a partial replacement for fine aggregate in M30 grade of concrete. Fine aggregate is partially replaced by PET at 0%, 15%, 17.5% and 20% were casted in the form of cube specimen, cylinder specimen and prism specimen of 24 each were casted and cured for 28 days for Compressive Strength, Split Tensile Strength and Flexural Strength tests respectively. It is observed that replacement of fine aggregate by PET at 17.5% improved the compressive strength upto 12.56% along with 14.58% and 37.79% improvement in split tensile and flexural strength.
