EXPERIMENTAL STUDY ON THE FLEXURAL BEHAVIOR OF E-WASTE PLASTICS IN CONCRETE

In this experimental work, the behaviour of shredded waste plastic (Bakelite) in concrete as partial replacement for aggregates is investigated. The percentage of replacement carried out in this work were 2%, 4%, 6%, 8%, 10% by weight of total aggregates. Moduli of rupture of shredded waste plastic plain concrete beams were found to be nominally less than that of control concrete. The flexural behaviour, deflection characteristics, stress vs. strain characteristics and crack patterns of reinforced shredded waste plastic concrete beams were found out. The use of shredded waste plastic increases the stiffness of the concrete which in turn reduces the ductility of the concrete. Specimen with 8% replacement of aggregates with waste plastic was found to be optimum which possesses high flexural strength, stiffness and ductility than other replacement specimens.
