GREY LATERITE STONE

Property	Typical Value
Density	~2.4–3.0 t/m³, average ~2.74 t/m³
Water Absorption	0.5–1.85 % natural; up to ~18% when used as bricks
Compressive Strength	1–3.5 MPa naturally; up to 13–25 MPa with cement/fly ash stabilization
Flexural/Tensile Strength	Generally low; not suitable for heavy structural loads
Porosity	High; initially soft when quarried, then hardens on exposure
Thermal & Insulation Properties	Excellent, providing cooling effect in hot climates due to Al/Fe oxides
Durability & Impact Resistance	Varies; can resist drops from ~1–1.5 m whitout breaking

Soft at mining, but rapidly hardens with exposure; durable like brick afterward
Loved for garden walls, paving, boundary walls, and low-rise houses in humid tropical climates.
Not suited for heavy-bearing structures (max ~2–3 storeys)
High porosity demands sealant applications when used in heavy rain zones.
