Recycled Waste Foundry Sand As A Sustainable

Waste sands are widely used in geotechnical applications and are divided into several major categories: foundry sands, raw slags, heavy ashes and metal fractions. Among these, WFS is commonly used due to its availability, mineral-rich properties and overall similarities in properties to natural and recycled sands (Saloke & Desai, 2011).
