Comparative Study of Plastic Sand Block Containing LDPE with Conventional Concrete

Abstract

The durability of plastics, as well as their very stable molecular configuration, has posed a threat to mankind and nature since its invention. Getting these plastics recycled turns the garbage into gold. A well-designed, heavy-duty, durable plastic block thus comes to the rescue. However, as a result of less attention given to this field, the manufacturers have yet to come up with a plastic sand block that can be efficiently and effectively used in the housing industry. The said block will not only help reuse discarded plastics in a way that keeps them away from landfill sites for a considerable period of time but will also help minimize the carbon footprint level of the concrete industry.in addition to that, as a result of the universal availability of sand, the blocks thus curated will also be affordable and can be used globally. In this particular study, plastic sand blocks were forged in different ratios, and different kinds of strength tests were performed on them to check for their suitability in the housing industry. An optimum range of 65% to 85% of plastic content was deduced towards the later stage of the experiment, within which the said blocks showcased significantly high compressive strength in comparison to regular concrete with no sign of cracks or disintegration for a very considerable displacement value. This invariably results in a block wherein no compromise needs to be made with strength or workability to achieve a better, more suitable and eco-friendly alternative to concrete.
