In the current research polystyrene particles are added to the concrete mix to produce six strips of reinforced slabs, in order to study the strips bearing capacity at the age of 56 days then later at 10 years. A selected mix of specific w/c is used; the main properties of the mix were studied from the results of casting cubes and beams. The results indicated that the L.W.C containing the polystyrene particles may be used to manufacture reinforced slab strips, in addition and as a by product to fabricate precast building blocks.
