Replacement of Coarse Aggregate with Expanded Polystyrene Beads to Achieve Lightweight Concrete

In this study, we explore how replacing traditional coarse aggregates with Expanded polystyrene (EPS) beads can enhance the properties of concrete. Lightweight concrete is valued in construction for its reduced self-weight, which eases handling and reduces load on structures, as well as for its superior thermal insulation and soundproofing qualities. By integrating EPS beads, which are known for being light and insulating, we aim to push these benefits even further. Concrete has to be designed based on density factor to accomplish reduction of the concrete self- weight with is ranging from 2000kg/m3 to 990kg/m3 total volume of EPS 0-100% and water cement ratio 0.45 Structural self-weight is quite important it shows a maximum portion of the load details. The main aim is to design EPS lightweight concrete according to standard concrete mix proportion. This mix proportion includes replacement of the conventional coarse aggregate by Partially or complete part with EPS beads, which ensures concrete workability and density. To study the properties of concrete like workability, compressive strength, Split tensile strength and Flexural strength test with partial replacement of course aggregate with expanded polystyrene beads EPS in concrete. Various test was conducted for fresh and harden concrete to know physical and mechanical properties of concrete at age of 7, 14 and 28days. Green construction is becoming a more important global problem and a key approach to conserve biodiversity and limit the amount of waste that ends up in landfills. To ensure the success of this investigation, coarse aggregate, cement, sand, water, and EPS beads with a diameter of not more than 10mm will be employed. In addition, four trial mixes must be made. The outcome indicates that increasing the quantity of EPS beads there will be decreasing strength of concrete with reduction in density. We can also Comparision strength for both conventional and lightweight concrete, which also makes us to the differentiate in cause of use.
