Product type
River sand is a naturally occurring granular material composed of finely divided rock and mineral particles. It is typically formed through the weathering and erosion of rocks, which are then transported by river systems. River sand is characterized by its smooth texture and rounded grains, making it ideal for various construction applications. It is commonly used in concrete production, mortar mixes, and as a base material for various construction projects.
| Grain size | 0.075 mm to 4.75 mm |
| Color | Light brown to yellowish |
| Moisture content | Typically 1% to 5% |
| Specific gravity | 1.5 to 1.7 |
| Chemical composition | Silica (SiO2) is predominant |
When selecting river sand, buyers should consider the grain size and moisture content, as these factors can significantly impact the performance of the material in construction applications. It's also important to specify the intended use, as different projects may require varying levels of purity and grain characteristics. Additionally, inquire about the source of the sand to ensure it meets local regulations and standards.
