About the statistical interpretation of air permeability assessment results

The reinforcement protection provided by a concrete cover of proper thickness and resistant to the penetration of aggressive agents is a key factor for the durability of reinforced concrete structures. The most efficient way to achieve adequate resistance to the penetration of aggressive agents is a performance-based specification of concrete, complemented with a suitable site control of the specified performance. The results from near-surface air permeability tests are presented in this paper, and their correlations with compressive strength, water–cement ratio and carbonation resistance are analyzed using different statistical parameters as representative values of each set of air permeability measurements.
