The extensive use of conventional concrete has a negative impact on sustainable use of materials, resources, and environment. The introduction of aggregates of the recycled materials will no doubt be beneficial to certain extent. The lightweight concrete (LWC) can be an alternative material to the conventional concrete to be used in the building industry. The life spam of any built environment is limited to many decades, thus the availability of aggregates of recycled materials by utilizing waste products from demolished building, together with the Expanded Polystyrene Beads (EPS) that is abundant in an oil producing country like Iraq can be constructed, six mixes of LWC-EPS (0%,20%, 40%, 60%, 80%, and 100%) were constructed and tested in this study. The research methodology consisted of investigating the fresh features of LWC due to the impact of utilizing various EPSs percentages on LWC, while the second part concentrated on testing LWC mixtures that had been hardened for compressive strength, splitting tensile strength, dry density, water absorption, and air void content. The findings of this study revealed that while compressive and splitting tensile strengths decreased, the fresh characteristics of LWC were only marginally improved by the inclusion of EPSs. As EPS tends to form larger clumps, absorb water, and dry out the mix, the study also showed that the LWC created with these waste materials lowered the density (lightweight) of the concrete mixes. This available investigation shall be of a use by architects, building engineers, researchers, and academics.
