  • Abstract:
  • The Lightweight materials include expanded polystyrene (EPS) light weight concrete have been employed in engineering applications. The Expanded polystyrene beads are the material which replaced in the place of fine aggregate. These factors will lead the concrete to become lighter and have a lower density. In this investigation the concrete density is reduced by adding polystyrene beads to the silica-fume concrete. Silica-fume was added for enhancing the concrete strength and balances the loss in concrete strength due to the inclusion of polystyrene beads. It has good thermal insulation properties with stiffness and compression strength. It is used in sound and vibration damping, settlement reduction beneath embankments, and related applications. The expanded polystyrene beads are used in varying proportions such as ( EPS0, EPS1 and EPS2 ) for replacing fine aggregate also cement is replaced with silica fume as 10% of total bender content as it shown similar pozzolani property as that of cement. The water-cement ratio was 0.41 and the sand-cement ratio was chosen. The tested for mechanical properties, durability properties and Non destructive tests.
