Sažetak

This article describes the possibilities in using recycled, ground expanded polystyrene (EPS) as aggregate for lightweight concretes as thermal insulation or as a structural concrete. The article presents a rich experience and provides explanation on the benefits of using ground EPS aggregate compared to virgin EPS beads in making lightweight concrete. A reinforced lightweight concrete structure made by SU-styrol – technology is also presented. Although the compressive strength of this lightweight aggregate concrete is six times less than that of ordinary concrete, the deformation (deflection) and the load-bearing capacity of the reinforced slab and that of the Su-styrene reinforced concrete and of the ordinary reinforced concrete slab are the same, which is very interesting. The authors have provided a physical interpretation of this behaviour, with the conclusion that the reinforced SU-styrol lightweight concrete is compatible with steel, unlike ordinary concrete. The authors hope that this paper will be a positive motivation for other researchers to explore this interesting topic.
