Replacement of Sand with Shredded Plastic in Cement Concrete

the increasing demand for plastic materials due to population growth, leading to a rise in plastic waste generation. Simultaneously, the construction of buildings is increasing, causing a shortage of natural aggregates. To address both issues, the idea of using plastic waste in building construction by partially substituting natural aggregates with plastic waste is proposed. Various percentages of replacement (10%, 20%, 30%, 40%, and 50%) were examined, as complete replacement of natural fine aggregate with plastic fine aggregate is not feasible. The compressive strength and workability of concrete prepared with these different percentages of plastic fine aggregates was tested.
