Solid waste could negatively affect the environment. Problems stem from factors such as the difficulty of waste recycling and limited reuse. Plastic is an important type of solid waste with a strong negative environmental impact. To improve sustainability and reduce usage of natural resources, innovative solutions are required. Incorporating crushed plastic waste as replacement for aggregate is one such innovative solution that can be adopted. This study aims to investigate the effects of utilizing recycled plastic waste as a partial substitute for fine aggregate in concrete. The effects of recycled plastic on the mechanical properties of concrete were studied. Both the fresh (workability) and hardened properties (unit weight, compressive strength, splitting tensile strength, pulse velocity and impact strength) of concrete were investigated. For this, substitution levels of 10%, 20%, and 30% were adopted for the experimental studies. Additionally, silica fume was also used for partial replacement of cement. A machine learning model to predict the compressive strength of concrete containing recycled plastic aggregate was also developed.
