Coarse sand is a granular material composed of small rock and mineral particles, typically ranging from 0.5 to 2 millimeters in diameter. It has a gritty texture and larger grains compared to fine sand, often appearing in shades of beige, yellow, or brown depending on its mineral composition. Derived from natural sources like riverbeds, beaches, or quarries, coarse sand is minimally processed, retaining its angular or rounded grains.
Uses of Coarse Sand:
- Construction and Concrete Production: Coarse sand is a key ingredient in concrete mixes, providing strength and stability when combined with cement, gravel, and water. Its larger grains enhance the structural integrity of concrete used in foundations, slabs, and roads.
- Masonry and Plastering: It serves as a base material in mortar for bricklaying and plastering, ensuring a strong bond and smooth application.
- Landscaping and Gardening: Coarse sand improves soil drainage in garden beds and is used as a base for paving stones, patios, or walkways, preventing waterlogging and ensuring stability.
- Filtration Systems: Due to its grain size, coarse sand is used in water filtration systems, such as in pools or wastewater treatment, to trap debris while allowing water to pass through.
- Sports and Recreation: It is used in creating surfaces for sports fields, like volleyball courts or golf course bunkers, providing a firm yet cushioned texture.
- Road and Pavement Base: Coarse sand is layered beneath asphalt or pavers to create a stable, well-draining foundation for roads and driveways.
Its durability, drainage properties, and versatility make coarse sand essential across construction, landscaping, and industrial applications.
