Silica Sand Kalimantan is a type of building sand sourced from the Kalimantan region, typically mined from rivers. This sand is known for its good quality and is widely used in various construction projects across Indonesia, especially in the Sumatra and Java areas.

Silica Sand Kalimantan is often categorized as concrete sand due to its strength and suitability for structural work, but it is also available in finer textures for finishing work.

Key Characteristics for Sales:

• Texture: Silica Sand Kalimantan is available in varied textures, ranging from fine to coarse/somewhat hard.

  • The fine sand is ideal for wall plastering, tile installation, or final smoothing coats (acian).

  • The coarser sand (often called casting/concrete sand) is excellent for concrete pouring.

• High Silica Content: Kalimantan sand generally has a high silica (Si) content (which can reach around 85% or more), making it strong and hard, which is crucial for high-quality concrete mixtures.

• Color: The color of Kalimantan sand can vary, but it often tends to be dark (black) or gray.

• Quality: It is considered a high-grade sand that is strong and sturdy, making it recommended for projects requiring structural strength.
