Production of Construction Bricks by Partial Replacement of Waste Plastics

Abstract

Plastics are the one which posses important problem in disposal and still the absolute solutions were not determined. For solving this issue plastics were replaced in a bricks to achieve the nominal strength. High-density polyethylene (HDPE) and polyethylene (PE) plastic bottles and bags were collected and cleaned then mixed with sand with various proportions to achieve the strength of the nominal bricks and also to posses thermal and sound insulation .To predict the strongest specimen, 0 % to 20% of replacement proportion was done by crushed plastics. The result in increase the strength of structure and weight reduction of bricks was tested for compressive strength and water absorption test. Based on the comparison of conventional and fly ash plastic brick, optimum strength was analyzed. This paper reviews the reduction of plastic disposal and the results are clearly shows that some part of plastics can be definitely used in the production of bricks.
