Plastics are hazardous materials and are very difficult to decompose, as they emit large quantity of toxic gases into the atmosphere during production. More than one-third of all domestic plastic waste is made up of dairy packaging, such as milk and buttermilk pouches, yogurt cups, and ice cream containers. Hence, recycling of waste plastic is necessary [1]. In present study, an attempt is made to utilize low-density polyethylene (LDPE) in the manufacturing of pavement elements. LDPE plastic obtained from waste plastic milk covers is used in manufacturing kerbstone. Kerbstone is manufactured with varying proportions of cement, such as 0, 25, 50, 75, and 100%, with plastic and compared with conventional concrete kerbstone. From the study, it is observed that the compression strength 11.37 N/mm2 of homogeneous kerbstone (only plastic as raw materials) is higher than compression strength of conventional kerbstone. It is also observed that the compressive strength 12 N/mm2 is higher when 25% of plastic and 75% of cement is used as binders compared to other combinations.

摘要

Plastics are hazardous materials and are very difficult to decompose, as they emit large quantity of toxic gases into the atmosphere during production. More than one-third of all domestic plastic waste is made up of dairy packaging, such as milk and buttermilk pouches, yogurt cups, and ice cream containers. Hence, recycling of waste plastic is necessary [1]. In present study, an attempt is made to utilize low-density polyethylene (LDPE) in the manufacturing of pavement elements. LDPE plastic obtained from waste plastic milk covers is used in manufacturing kerbstone. Kerbstone is manufactured with varying proportions of cement, such as 0, 25, 50, 75, and 100%, with plastic and compared with conventional concrete kerbstone. From the study, it is observed that the compression strength 11.37 N/mm2 of homogeneous kerbstone (only plastic as raw materials) is higher than compression strength of conventional kerbstone. It is also observed that the compressive strength 12 N/mm2 is higher when 25% of plastic and 75% of cement is used as binders compared to other combinations.
