Description

Sand is a vital material in construction, primarily used in concrete, mortar, plaster, and as a base for foundations. It consists of small, granular particles, typically made of minerals like quartz. Key uses include:

• Concrete Production: Sand forms a key aggregate in concrete, providing bulk and strength.
• Mortar: Mixed with cement, it bonds masonry units.
• Plaster: Used with cement or lime for wall finishes.
• Backfilling and Foundations: Provides a stable base for structures.
• Landscaping: For leveling surfaces and improving drainage.

Types: River sand is most commonly used due to its cleanliness, while desert sand is unsuitable for construction.

Properties: Good construction sand should be clean, angular, and free of impurities to ensure strength and durability.

Overall, sand is indispensable in construction, but over-extraction poses environmental concerns, leading to the exploration of alternatives like crushed rock.
