How can sand be effectively used as insulation in construction projects?

Sand can be effectively used as insulation in construction projects by creating a layer of sand between two walls, which helps to trap air and reduce heat transfer. The small particles of sand create pockets of air that act as insulators, preventing the loss of heat or cold. This method is cost-effective and environmentally friendly, providing thermal insulation for buildings.


Why is silica sand mainly used in moulding sand?

Silica sand is primarily used in moulding sand due to its excellent thermal stability, high melting point, and ability to withstand the high temperatures encountered during metal casting. Its granular structure provides good permeability, allowing gases to escape during the casting process, which helps prevent defects in the final product. Additionally, silica sand is abundant and cost-effective, making it a practical choice for foundries.
