This paper addresses the challenge of evaluating the air permeability of structural concrete
in situ, using non-destructive techniques. Specifically, it aims to reconcile air permeability …

Permeability is an important characteristic associated with the durability of cementitious
materials. Gas permeability testing could overcome some shortcomings of traditional …

In the domain of inspection of civil structures, the evaluation of permeability in the field is a
major problem of durability for all engineering structures using concrete. Specifically …

Gas permeability is a crucial factor influencing the durability of cement-based materials,
which are usually in a partially saturated state. This study examines the impact of the water …

Assessing the permeability of concrete is crucial as it governs the transport of aggressive
agents, such as chlorides and carbon dioxide, which are key factors in the degradation …

This work estimates air leakage through concrete porosity for structures by using data
obtained in field combined with stochastic finite element (SFE) modelling. For this purpose, a …

A 3-D continuum mixture model describing the corrosion of concrete with sulfuric acid is
built. Essentially, the chemical reaction transforms slaked lime (calcium hydroxide) and …

Air permeability measurement is critical for assessing the integrity of nuclear containment
structures, especially in safety-critical environments such as nuclear power plants. This …

In this work a combined laboratory-based and neutronographic investigation was carried out
on a type of limestone, known as Pietra di Lecce stone, widely used in Italian Baroque as …

A series of tests are reported which used existing pressure cell apparatus to measure
nitrogen gas flow in concrete. A finite difference numerical model is described which is used …
