Explanation:
Laterite soils are used as a building material because they become hard like iron when exposed to air.
They are very rich in iron. They are poor in lime, magnesium, phosphoric acid and potash.
All these properties of laterite soil make it unique as a valuable building material.
Laterite or lateritic soil remains one of the best natural materials to be used in compressed earth bricks, because, it is generally well graded soil that combines both cohesive (silt and clay) and the cohesionless (sands and gravels) parts of a soil.
