in concrete. Waste foundry sand is a waste material obtained from ferrous and non-ferrous metal casting industries. In foundry industries sand is recycled and reused many times for the purpose of casting. When the sand finds no advantage in this industry, it is disposed as a waste material, and termed as waste foundry sand (WFS).
