Abstract

The aim of this study was to assess decay patterns occurring after artificial weathering induced by Na2SO4 crystallization cycles in the 2 types of granite most commonly used for building construction in the city of Madrid : the Zarzalejo and Alpedrete granites. Decay assessment focused on the relationship between physical–chemical weathering features characterized under polarized light optical microscopy, environmental scanning electron microscopy, mercury intrusion porosimetry, water absorption and ultrasound propagation on the one hand, and the variation in surface roughness in mineral grains located on the surface edges, corners and centres of granite specimens on the other, as a method for quantifying decay and consequently durability of the 2 varieties of granite
