Key parameters of volcanic tuffs used as building stone: a statistical approach

Abstract Volcanic tuffs naturally show a strong heterogeneity in their petrography and petrophysical properties. The arrangement of the components can create very wide spectrum porosities fabrics, which turn lead to highly differential weathering behavior. Considerable amounts clay minerals zeolites are common contribute high sensitivity expansional processes salt crystallization. Understanding influence rock properties on material behavior durability help make predictions future evaluate suitability for construction purposes. This study presents petrographic data 15 selected 513 from literature used as building stones. Regression analysis if parameters comparable key be identified. Key potentially estimation behavior, without use expensive analytics or simulations.
