|---|---|
| Description | Laterite Shilā (Laterite Stone) is a porous, iron-rich soil hardened into rock, common in tropical regions. It consists primarily of goethite, hematite, and kaolinite. Density ranges from 1.6 to 1.9 g/cm³, with compressive strength varying from 2 to 20 MPa depending on the degree of induration. |
