Characterization of strength and toughness properties of metalized plastic waste fibre reinforced concrete

Abstract

Recycling of plastic waste in concrete has drawn much attention nowadays. The influence of metalized plastic waste fibres on M30 grade concrete was investigated in this study. Strength and toughness properties were evaluated and compared with the control concrete made without addition of fibres. Fibre dosages 0%, 0.25%, 0.5% and 0.75% are taken as a parameter of study. The mechanical properties such as compressive strength, split tensile strength and flexural strength were analyzed to understand the performance of the metalized plastic waster fiber reinforced concrete. Load-deflection curves are plotted to estimate the toughness (energy absorption capacity) characteristics of the composite at the age of 28days.Increase in MPWfibre content in concrete improved the split tensile strength upto 54% and flexural strength upto 58%, but marginal improvement in compressive strength is observed. MPWfibre reinforced concrete outperformed in flexural toughness and it exhibited 2.92 folds superior toughness with 0.75% fibre addition when compared to 0.25%.
