Abstract
Industrial-scale paving blocks were produced using four recycled construction-and-demolition aggregates (C&DW) under standard factory conditions, with optimized dosages and three mix designs. Mechanical evolution, service properties and ionic leaching were assessed; data were analyzed with principal component analysis (PCA). Results indicate that most recycled aggregates can replace ~25% of natural aggregate in vibro-pressed precast concrete while meeting UNE-EN 1338 performance requirements. All blocks were environmentally safe per the Netherlands Soil Quality Decree (no leaching risk), supporting industrial uptake of recycled aggregates in non-structural concrete.
