AN INVESTIGATION OF THE PROPERTIES OF CONCRETE CONTAINING GRANULATED PLASTIC BOTTLE WASTE AS A PARTIAL REPLACEMENT OF FINE AGGREGATES

ABSTRACT
Solid waste is one of the major environmental issues facing our country today. This study is
focused on the use of granulated plastics as a partial replacement of fine aggregates in concrete.
The aim was to investigate the characteristics of concrete with the addition of plastic and
comparing it with the control, thereby determining the advantages and disadvantages of doing
so.
In the lab concrete was mixed, cast, cured and tested. The fresh concrete was tested for slump
test and the compaction factor test, while the hardened concrete for compressive, tensile and
flexural strength. There were four batches, the control and 10%, 30% and 50% weight
replacement of sand with granulated plastic.
It was found that addition of plastic in concrete resulted in the formation of lightweight concrete.
The compressive, tensile, flexural strength of concrete reduced with the addition of plastic.
