Sustainable concrete pavers with alternative aggregate sources

Pilot product: Eco-friendly RAC paving elements
Location: Otočac
Technology: Recycled aggregates concrete
Ash type: Sewage sludge ash
Ash replacement level: 4 wt.% of the total aggregate

RAC pavers were produced using SSA as a partial replacement for natural aggregates. Incorporating these alternative materials promotes resource conservation, supports ecosystem protection, and advances sustainable construction practices. The demonstration was carried out in collaboration with the elementary school in the municipality of Mušaluk, the precast concrete producer Beton Lučko d.o.o., DOK-ING d.d. and the University of Zagreb Faculty of Civil Engineering.
