Water and chloride ions migration in porous cementitious materials: An experimental and molecular dynamics investigation
TL;DR: In this paper, the interactions of water and chloride ions penetration into porous mortar have been investigated experimentally and modelled by molecular dynamics, showing that separation of chloride ions from water during the penetration process took place and water ran much deeper into the material than chloride ions.

Steel reinforcement corrosion in concrete under combined actions: The role of freeze-thaw cycles, chloride ingress, and surface impregnation
Peng Zhang,Peng Zhang,Cong Yuan,Michael Vogel,Zhaolin Liu,Harald S. Müller,Yaguang Zhu,Tiejun Zhao +7 more
TL;DR: In this paper, the influence of freeze-thaw damage on chloride penetration into concrete, and consequently on steel reinforcement corrosion have been investigated, and it was concluded that chloride penetration can be accelerated considerably by freezethaw cycles.

Application of neutron radiography in observing and quantifying the time-dependent moisture distributions in multi-cracked cement-based composites
Peng Zhang,Peng Zhang,Penggang Wang,Penggang Wang,Dongshuai Hou,Zhaolin Liu,Michael Haist,Tiejun Zhao +7 more
TL;DR: In this article, the authors applied neutron radiography to visualize the process of water penetration into cracked SHCC and to quantify the corresponding time-dependent moisture distributions in the cracks, and they found that the amount of water and the penetration depth increased with increasing of crack density and the wider crack pattern when higher tensile strain was applied.

Numerical and experimental investigation of coupled capillary suction and chloride penetration in unsaturated concrete under cyclic drying-wetting condition
TL;DR: In this paper , a mesoscale numerical modeling of chloride penetration coupled with capillary suction in unsaturated concrete exposed to cyclic drying-wetting condition is presented. But the results indicate that the established model can accurately predict the coupled transport of water and chloride in unstructured concrete under cyclic driewetting condition.

3D neutron tomography of steel reinforcement corrosion in cement-based composites
TL;DR: In this paper, the steel corrosion in both ordinary mortar and strain hardening cementitious composites (SHCC) has been for the first time visualized by means of neutron tomography in three dimensions with high resolution.
