Abstract:
Plastic wastes are increasing at an alarming rate and adversely affecting environment as they are not
easily degraded. This paper researches to replace cement with plastic waste in paver block and to reduce
the cost of paver block as well as utilizing waste HDPE plastic in manufacturing of paver blocks as
compared to that of convention concrete paver blocks. The project aims in reducing plastic waste in a
useful way and reduce pollution from environment also making paver block economical. According to a
study in Science Magazine, Malaysia is the 8th worst country worldwide for plastic waste. It is estimated
that, Malaysia produced almost 1 million tonnes of mismanaged plastic waste in 2010 of which 0.14 to
0.37 million tonnes may have been washed to the oceans. Objective of this project is to produce paver
block using HDPE plastic. Hence, investigate the compression strength, water absorption and melting
point of plastic paver block and compare it with conventional block available in the market. Four type of
paver block with size 225mm × 115mm × 60mm were prepared forthe experiment. In this project we have
used plastic waste and sand with different proportion. Four samples were prepared (50:50), (60:40) and
placed in mould. Afterwards, the respective samples were tested for compressive strength. Compressive
strength test showed the values of 13.2N/mm2 (60:40) ( coarse sand : plastic), 9.1 N/mm2 (50:50) ( coarse
sand : plastic), 7.9 N/mm2 (60:40) ( fine sand : plastic ) and 11.6 N/mm2 (50:50) ( Fine sand : plastic ).
Water absorption testshowed an average value of 1.8 % which is lower compared to the cement concrete
made pavers. The research concluded that it can be used in non-traffic and light traffic roads. Gardens,
pedestrian path will be cheaply constructed, and with the increased durability, accessibility will be
improved and well utilization of resources. For the recommendations, the strength of the paving block
can be increased by adding more materials in the mixture such as Kaolin which can result in higher
compression strength.
