No, silica sand is generally not considered "building sand" in the typical construction sense. While it can be used in certain building applications, "building sand" usually refers to sand specifically graded and prepared for use in concrete, mortar, and other common construction materials.
Understanding the Difference
The key difference lies in the intended use and properties of each type of sand:
- Silica Sand: This sand is composed primarily of quartz (silicon dioxide). It's valued for its high purity, hardness, and chemical inertness. It has specialized uses.
- Building Sand (Also known as Construction Sand or Sharp Sand): This sand is a more general term for sand used in a variety of construction applications. It's not necessarily pure silica.
Uses of Silica Sand
Silica sand is commonly used in:
- Glassmaking: Its high silica content makes it ideal for manufacturing various types of glass.
- Sandblasting: Its hardness makes it suitable for abrasive cleaning.
- Water Filtration: Its particle size and inertness make it a good filtration medium.
- Silicon Metal Production: A raw material in the production of silicon metal, used in electronics and solar panels.
- Specialty Concrete: In applications where chemical resistance is needed.
Uses of Building Sand
Building sand is typically used in:
- Concrete Mixes: Providing bulk and strength.
- Mortar: Binding bricks and blocks together.
- Asphalt: Used in road construction.
- Base Material: For pavers, patios, and other landscaping projects.
Why Silica Sand Might Not Be Ideal for General Building
While silica sand could technically be used in some building applications, it often isn't the most cost-effective or practical choice. Building sand is typically cheaper and readily available in the necessary grades for concrete and mortar production. The high purity of silica sand is often unnecessary (and potentially undesirable, depending on the application) for general construction purposes. Furthermore, the particle size distribution of silica sand might not be optimal for achieving the desired workability and strength in concrete or mortar. Specific types of silica sand, such as very fine grades, might even weaken a concrete mix.
In Summary
Building sand is a more general term for sand used in construction, while silica sand has specific properties making it suitable for industrial applications. Although silica sand could be used in some construction contexts, it is not the primary or typical "building sand."
