Waste usage in the construction industry has reduced global environmental pollution. Reusing waste materials as substitutes for cement in concrete constituents and other construction materials can lower cement and concrete manufacturing costs, solid waste, and landfill space. Engineers are still unsure as to what extent waste can be repurposed to produce optimal strength for the production of concrete. Reutilization of waste materials has been employed in this paper by adopting 3.5%, 7%, and 10% of six wastes (plastic bags, rubber tires, cement sack strands, can waste, PET bottles, and waste from glass) as substitutes for aggregate in concrete production. At 10% replacement, the cement sack strand absorbed more water than other waste materials and about 5.8% less than the control specimen. Despite the fact that glass waste has a low water absorption rate, there was no discernible increase in strength after 28 days due to brittle damage under loading. At 10% and 7% partial replacement, can waste had about 9% and 12.5% higher compressive and tensile strengths than the control specimen. As a result, it is proposed that using wastes that may enhance concrete properties will lower the need for normal coarse and fine aggregates, enabling natural resource conservation.
