SILICA
JAWA
Silica Sand Jawa is commonly used material for building dst
Concrete Sand (Casting Sand): Silica Sand Jawa is classified as excellent concrete sand.
Coarse and Hard Texture: It has coarse and hard grains (ranging from slightly fine to coarse). This strength is crucial for producing sturdy and strong concrete mixtures.
Low Silt/Mud Content: Good sand for construction must have a low silt/mud content. Silica Sand Jawa generally has a low silt content, making it an ideal choice for cement mixtures.
Color: Generally yellowish-brown.
