| dc.description.abstract | The increasing population has led to an increase in human activities, including the
construction of infrastructure by communities. This has resulted in changes to land
use, such as converting open land into residential areas, and an increase in
sedimentation in drainage systems, largely due to plastic waste. These issues
contribute to flooding, where water easily accumulates. Therefore, addressing this
problem is essential. One solution is to build infiltration wells. By using lightweight
porous concrete with PET plastic waste as the well wall material, installation can
be simplified without requiring extensive labor. Additionally, this approach
facilitates water infiltration into the well and reduces plastic waste accumulation.
The experimental method involved mixing PET plastic waste aggregates at varying
percentages (0%, 10%, 20%, 30%, 40%, and 50%). The highest compressive
strength was achieved in variation 50% PET (3,603 MPa), while the highest tensile
strength occurred in variation 50% PET (0,566 MPa). The highest flexural strength
was observed in variation 50% PET (0,933 MPa), and the highest infiltration rate
was in variation 30% PET (0,0294 mm/hour). The optimal composition for
constructing porous concrete infiltration wells is variation VI. The weight of four
segments of a 100-meter-high well wall is 254,740 kg | en_US |
