Chemical analysis of silica sand and comparing it with standard sand.
| Type of sand | SiO2 | Fe2O3 | Al2O3 | CaO | Na2O | K2O | MgO | LOI (loss on ignition) |
| Silica sand used in this study (%) | 97–99 | 0.2–0.6 | 0.4–1.7 | 0.07–0.2 | 0–0.01 | 0.02–0.06 | 0 | 0.01–0.35 | Standard sand (%) | 96–98.1 | 0.2–0.7 | 0.51–1.63 | 0.4–0.7 | 0.03–0.8 | 0.02–0.08 | — | — |
