Dark Grey Sandstone Handling and Storage

• Avoid dark cracks or damage caused by rolling and collision.
• When storing outdoors, avoid prolonged exposure and direct sunlight.
• In winter construction, cover the stone with rock wool and move it indoors 4 hours before paving to allow melting.
• During the rainy season, cover the construction area with a tarpaulin to prevent the stone from getting wet.

Distinguishing Sea Sand and River Sand

1. Appearance Differences
• Sea Sand: Dull, dark brown, sometimes lighter in color. Contains shells and other debris.
• River Sand: Brighter yellow, with pebbles of different sizes.
2. Chloride Ion Content Measurement
• Use an ion-selective electrode method to quickly determine the water-soluble chloride ion content in materials like concrete, gravel, and cement.
• This prevents premature corrosion of concrete reinforcement.
• A chloride ion content analyzer is lightweight, compact, and easy to carry, making it suitable for on-site testing.
