Physical properties of sands.
| | Sand type | Apparent density
(kg/m3) | Specific density (kg/m3) | Porosity in percentage | Fines modulus (MF) | Water content in percentage | Sand equivalent in percentage |
| | Dune sand (0/2.5 mm) | 1610 | 2650 | 40 | 2.21 | | 90.52 | | Crystallized sand slag (0/3.15 mm) | 1570 | 2630 | 41 | 3.1 | 0.35 | 88.52 |
