TYPES OF SAND ⋆ Archi-Monarch

Sand is a granular material that consists of rock fragments, minerals, shells, or other small particles. It is typically composed of particles ranging in size from 0.063 to 2 mm in diameter and can be found in a variety of colors, including white, yellow, brown, and black. Sand is formed by the weathering and erosion of rocks and minerals, and it is often transported by wind, water, or ice.

In construction, sand is a crucial material used in various applications, including concrete and mortar production, bricklaying, and landscaping. The different types of sand have varying properties that make them suitable for specific applications, and choosing the right type of sand is critical to ensuring the structural integrity and longevity of building structures.
