Deterioration of a concrete surface due to the oxidation Slate University of Auckland

Formation of this mineral was the cause of faiktre where decay of pyritic slate 3 and degradation of a bituminous pavement laid on pyritic shale 4 had occurred The presence of this mineral indicates a severe attack due to pyrite oxidation on mineral components of the aggregate such as chlorite or other A1 and Mg bearing minerals The latter blistered zone also appeared to contain other Slate Slate is a low grade metamorphic rock generally formed by the metamorphosis of mudstone / shale or sometimes basalt under relatively low pressure and temperature conditions
