River sand is a naturally occurring material obtained from the banks of rivers and river beds. It is formed by the continuous erosion of rocks and minerals over thousands of years. Due to its natural weathering processes, river sand possesses smooth, rounded particles, which make it highly workable. Due to its workability, river sand is a type of sand used in construction tasks that require precision and attention to detail, such as bricklaying, plastering, and concrete mixing. Its rounded particles make it easy to mix and place accurately, making it a popular choice for projects demanding precision.

River sand is prone to variations in quality and gradation, which can affect the workability of concrete. It may contain organic and inorganic impurities such as silt, clay, vegetation, shells, and salts. These impurities can affect the strength and durability of the construction. 

The increasing demand for river sand has led to excessive mining, causing environmental concerns such as river bank erosion, groundwater depletion, and loss of biodiversity.
