No, all-purpose sand is not the same as river sand, although they share some similarities.
River sand, as the name implies, is naturally sourced from riverbeds and banks. It's typically smoother and rounder due to the continuous erosion by water. All-purpose sand, on the other hand, is a broader category encompassing various types of sand that are suitable for general construction or landscaping projects. The key differences lie in their origin, particle size, and intended use.
Here's a breakdown:
- Origin: River sand is naturally occurring; all-purpose sand can be naturally occurring or manufactured.
- Particle Shape: River sand tends to have a more rounded shape due to water erosion. All-purpose sand can have varying particle shapes depending on its source and processing.
- Purity: River sand often requires washing and screening to remove organic materials and debris. All-purpose sand is usually processed to meet specific purity and grading standards.
- Use: While some overlap exists, river sand is excellent for drainage, landscaping, and concrete mixes. All-purpose sand is designed for various applications, including concrete, paving, and base materials. It is often screened more precisely for consistent performance in a wider range of applications.
- Pebbles: River sand may contain small pebbles. All-purpose sand is generally free of large pebbles, though some coarser grades might exist.
In summary, while river sand can be used as an all-purpose sand, the term "all-purpose sand" refers to a more controlled and graded product suitable for a broader range of applications, and all-purpose sand may not have the same rounded shape, and therefore drainage capabilities, of river sand.
