Must be silica sand (non- calcareous). 4. Must meet the following particle size distribution: Fine Gravel: 2.0 – 3.4 mm - Not more than 10% of the total particles in this range. Very Coarse Sand: 1.0 – 2.0 mm - With a maximum of 3% fine gravel (preferably none). Coarse Sand: 0.5-1.0 mm - > 70% combined coarse + medium. Medium Sand: 0.25 – 0.50 mm - Sand with a minimum of 30% coarse. Fine Sand: 0.15 – 0.25 mm - < 15% of the particles within this range. Very Fine Sand: 0.05 – 0.15 mm - < 5% of the particles within this range. Silt: 0.002-0.05 mm - Less than 5% combined silt + clay in this range. Clay: < 0.002
