Testing

Water Absorption:: 10 - 15 By volume %
Density:: 2000 - 2250 kg/m3
Flexural Strength:: 4.3 - 5.0 MPa
Compressive Strength:: 20.9 - 27.7 MPa
Stone texture:: distinguished by its warm yellow to golden-beige coloration, sometimes showing pale straw-yellow, light ochre, or slightly greyish-yellow shades depending on the quarry layer. The stone typically presents a soft, earthy appearance with subtle tonal variations and occasional lighter or darker patches created by volcanic ash deposits and pumice fragments embedded in the matrix. Its visual character is generally uniform but naturally rustic, giving surfaces a warm Mediterranean architectural aesthetic often associated with traditional Italian masonry. Texturally, Tufo Giallo exhibits a fine-grained, porous and vacuolar structure typical of volcanic tuff, formed from compacted volcanic ash and pyroclastic materials; this results in a lightweight yet cohesive stone with numerous microscopic cavities and small pumice inclusions within a consolidated ash matrix. The structure is relatively soft and workable when freshly quarried but gradually hardens after exposure to air, making it easy to cut and shape while still providing adequate strength and durability for building elements.

Description
