The purpose of the paper is to investigate the abilities of applying Granulated Expanded Glass Aggregate (GEGA) as a natural volume substitute of aggregate as a component of lightweight concrete. The GEGA aggregates used in the experiments were made of confused glass waste. In order to achieve satisfactory strength of concrete Granulated Ash Aggregate (GAA) was added as well. To produce specimens three grain sizes of aggregates was used: 2 mm - GEGA, 4 mm - GEGA and 8 mm GAA. The influence was assessed of percentage participation of each aggregate in whole composite (0%, 25%, 50%, 75%, 100%) on the properties of lightweight concrete mix, on mechanical properties of lightweight concrete and its practical usage in thin shells. The series of 15 concrete mixes were prepared for various aggregate contents and for constant water-cement ratio (w/c = 0.5).
