COBIAX finally in Greece! In December 2019, COBIAX lightweight concrete slabs were introduced in the greek market.
Project country: Greece
Project location: Varko District in the Municipality of Aktio – Vonitsa, in the Regional Unit of Aitoloakarnania.
Builder: Napa Tourism Enterprises I.K.E.
Architect: Fotini Ksirafi
Structural engineer: Αntonios Kanellopoulos – Cubus Engineering
Executing company: Napa Tourism Enterprises I.K.E.
COBIAX slabs were placed in a complex of three statically independent buildings under construction in Varko District in the Municipality of Aktio – Vonitsa, in the Regional Unit of Aitoloakarnania. The buildings will be used as seaside villas.
When designing the building complex, one of the main goals of the engineering team was the maximum possible reduction of the slab weight and the slab height and the maximum possible increase of the span lengths. So using COBIAX slab was the best solution both compared to the relevant solid slabs and to slabs with girders (zoellner and sandwich type) which are widely used in Greece.
Three different types of the COBIAX SL were used in order to achieve three different slab thicknesses. More specifically, SL 120-140 was used for slabs of 25 cm thickness, SL 180-200 was used for slabs of 30 cm thickness, and SL 220-240 was used for slabs of 35 cm thickness.
The assembly of the semi-shells and their placement in the steel cages was done in the construction site using a wooden working mold.
A structural engineer of ENKA TECHNOLOGIES (representative of COBIAX in Greece) was in the construction site to oversee the correct assembly of the voidformer semi-shells and their installation in the formwork.
The whole process (assembly of the COBIAX voidformers, installation in the formwork, concrete purring) was easily executed, and the builder found it much easier than the slabs with girders (zoellner and sandwich type).
