Abstract
Study on valorizing diatomaceous earth wastes from food-industry filtration (wine, oil, beer) as supplementary cementitious material in conventional concrete. Five mixes were produced with 5% cement replacement (CEM I 42.5 R) using natural and recycled diatomite. Tests (compressive strength, capillary absorption, chloride permeability, carbonation) show that concrete with recycled diatoms (wine/beer) achieved up to ~16% higher compressive strength than the reference and exhibited lower capillary absorption, indicating a denser, less permeable matrix. The approach simultaneously diverts a problematic waste from landfill and reduces clinker use and associated CO₂.
