Washed sand, often called coarse sand, is sand that has been cleaned by washing to remove impurities like clay, silt, dust, and organic matter. 

Key Features:

• Coarse grain size: bigger than fine or medium sand.

• Clean: free from dirt, clay, and other fine impurities.

• Rough texture: helps it bond well in construction mixes.

Common Uses:

• Concrete production: provides strength and durability.

• Mortar mix: better adhesion for bricks and blocks.

• Plastering: rough surface for better bonding.

• Landscaping: used in drainage layers or base layers.

• Fill material: around pipes or foundations.

Benefits:

• Improves strength of concrete and mortar.

• Ensures good drainage in soil mixes.

• Reduces shrinkage and cracking.

• Easy to work with and durable.
