Influence of Incorporating Waste Glass Powder and Fine Waste Plastic Aggregate on Fresh and Hardened Properties of Structural Concrete

This research aims to create green concrete with acceptable characteristics by recycling glass and plastic waste together. Cement was partially replaced with a 15% waste glass powder by weight mixture and fine aggregates with a 5% waste plastic crushed mixture. According to the findings, adding glass alone to concrete enhanced its qualities, such as compressive strength, splitting tensile strength, flexural strength, energy capacity, and bond strength, compared to a reference sample. The splitting tensile strength increases with replaced cement by 15% glass by 5.4%. When replacing fine aggregate with 5% fine plastic, splitting strength decreases by 5.4%. Flexural strength increased by 1.6% when adding 15% glass to the reference mixture. On the other hand, replacing sand with plastic for concrete with 15% glass powder led to some properties of concrete being affected downwards
