Abstract
Managing plastic waste is a global challenge that
challenges the protection of our ecosystem due to its high rate of
generation and its non-biodegradability. PWs must, however, be
carefully handled to mitigate the emissions involved with their
incineration and dumping into landfills. Plastic waste can be
recycled into new usable building materials. In this analysis,
shredded PET waste aggregate from a recycling center was
heated at 230 0C and used as a binding aggregate incomplete
replacement of cement with river sand to produce floor tiles. The
properties of the aggregate materials and roof tiles (including
their distribution of particle size, silt, clay and dust content,
relative density, water absorption, porosity, flexural and
compressive strength) were tested on different PET waste: sand
mixing ratio, 100%, 90%, 70%, 50%, and 30%. Results revealed
that the tiles produced by 30% PET and 70% river sand (3:7)
achieved higher density, flexural and compressive strength than
the other percentages of the mixture. The compressive strength of
the tiles produced with 30 percent PET waste composition was
greater than that of cement concrete (at 28 days of curing) for
residential buildings. As a result of this low water absorption and
eco-friendliness, PET waste can be used for roof tiles at 30
percent PET substitution based on the test results.
