Plastic Mixed Reinforced Concrete - Behaviour

Abstract:

One of the main environmental problem today is the disposal of the waste plastics. The use of plastics in various places as packing materials and the products such as bottles, polythene sheets, containers, packing strips etc., are increasing day by day. This results in production of plastic wastes from all sorts of livings from industrial manufacturers to domestic users. To circumvent this pollution crisis, many products are being produced from reusable waste plastics. On the other side, the Indian construction industry is facing problems due to insufficient and unavailability of construction materials. So, we need to search for new construction materials as well as a method to dispose the plastic waste. To find a solution to the above problems, one of them can be used to solve the other. In this experimental study, an attempt has been made to use the waste plastics in concrete and studies have been conducted to focus particularly on the behavior of compression members with various proportions of plastic wastes. The plastics used in this investigation were polythene sheets, raw plastics (raw material used for straw manufacturing), road wastes (waste plastics collected from road sides are melted and shredded) and plastic straw. The above plastic wastes were mixed with cement concrete in various proportions (0.1% to 2%) and test specimens were cast (cubes and columns) to study the behavior of plastic mixed concrete in axial compression.
