Abstract :

Expanded polystyrene beads (EPS) is a lightweight material that has been used in construction applications since at least the 1950s. Its density is about a hundredth of that soil. It has good fire insulation properties with stiffness and compression strength comparable to medium clay. It is utilized in embankments sound to reduce the settlements and vibration damping, it reduces the lateral pressure on sub-structures, reducing stresses on rigid buried conduits and related applications. Expanded polystyrene waste in a coarse grained form is used as lightweight aggregate to produce lightweight structural concrete. The polystyrene aggregate concrete was produced by partially replacing coarse aggregate in the reference of normal weight concrete mixtures with equal volume of the coated crushed polystyrene granules is done chemically. This paper reports the results of an experimental investigation into the engineering properties, such as compressive strength, modulus of elasticity, dry shrinkage and creep coefficient of polystyrene aggregate concrete varying in density.
