River sand is a naturally occurring granular material composed of finely divided rock and mineral particles. It is obtained from riverbeds and is widely used in construction due to its clean, well-graded, and rounded particles. It is free from organic impurities and clay, making it suitable for concrete, mortar, plastering, and other structural applications.

Tayan sand is a natural mineral material primarily composed of silica (SiO₂) crystals, formed through the weathering of rocks containing quartz and feldspar. It is transported by water or wind and deposited near rivers, lakes, or coastal areas. This sand contains some impurities, such as iron oxide, calcium oxide, clay, and organic matter, which affect its color and purity. Tayan sand naturally occurs in various grain sizes, ranging from fine (0.06 mm) to coarse (2 mm).
