Waste Foundry Sand Usage for Building Material Production: A First Geopolymer Record in Material Reuse

<div>The relationship between CS values (7 and 28 days) and curing temperatures (100–200°C) for the WFS-based geopolymer materials produced by using 38 and 48 bome Na<sub>2</sub>SiO<sub>3</sub> (10–30% in total amount).</div>
