Study of Waste Plastic Mix Concrete with Plasticizer

Abstract EN

The fresh and hardened properties of waste virgin plastic mix concrete have been studied (CUR Report 1991).

A number of concrete mixes were prepared in which sand was partially replaced by waste plastic flakes in varying percentages by volume.

Waste plastic mix concrete with and without superplasticizer was tested at room temperature.

Forty-eight cube samples were moulded for compressive strength tests at three, seven, and twenty-eight days.

Eight beams were also cast to study the flexural strength characteristic of waste plastic mix concrete.

It was found that the reduction in workability and compressive strength, due to partially replacement of sand by waste plastic, is minimal and can be enhanced by addition of superplasticizer.
