Use of Plastic as Partial Replacement of Fine Aggregate in Fibre Reinforced Concrete

Modern activities in India leads to use of plastic bags in excess. Plastic being non-biodegradable material, it takes years to decompose. Plastic bags have main constituent as poly-ethylene. The poly-ethylene when combusted produces a by-product of Carbon dioxide which leads to global warming.In this,we study the efficiency of reusing plastic waste in concrete by comparing compressive strength of concrete whose fine aggregate is partially replaced by plastic(5%,10%,15%,25%) with control concrete of M20 grade. To compensate for the strength lost due to replacement, iron fibres of diameter 1-2 mm are used in fixed amount.
