Service Performance Evaluation Model of Marine Concrete Based on Physical Information Neural Network

Buildings
In this paper, an intelligent simulation method for chloride ion diffusion behavior in marine concrete is established based on a physical information neural network. The dimensionless constraint equation is constructed to solve the influence of different

The Evolution of Concrete Microstructure and Chloride-Ion Diffusion Coefficient Under Cyclic Axial Compression

International Journal of Concrete Structures and Materials
The changes of the microscopic pore structure for concrete under cyclic axial compression accelerate chloride-ion penetration, reducing the durability of concrete structures. To address this, a chloride-ion migration experiment for concrete was conducted

Controlling the interstitial element concentration in Ti-6Al-4V using calciothermic reduction [PDF]

, 2013
The production of Ti-6Al-4V components via powder metallurgy routes is looked upon as an efficient production method that reduces wastage, but leaves finished products with high interstitial oxygen concentrations that do not meet industrial standards ...

Influence of the ionic composition on the diffusion mass transfer of saccharides through a cation-exchange membrane [PDF]

, 2013
Recent studies have pointed out that the presence of salts can change significantly the membrane process performances because of the resulting modification of the neutral solutes transfer through the membrane.

Combined Kelvin probe force microscopy and secondary ion mass spectrometry for hydrogen detection in corroded 2024 aluminium alloy [PDF]

, 2013
The capability of Kelvin probe force microscopy (KFM) to detect and locate hydrogen in corroded 2024 aluminium alloy was demonstrated. Hydrogen was introduced inside the 2024 alloy following a cyclic corrosion test consisting of cycles of immersion in 1 ...

Characteristic of Chloride Ion Diffusion in Mortar Mixed with Ion-Exchange Resin

Concrete Research and Technology, 2013
Recently, a number of concrete structures constructed several decades earlier are showing significant degradation, especially in coastal areas. For the effective repair and reinforcement of such structures, the development of high performance repairing material is required.

The diffusion of chloride ion in cement paste.

, 1992
The effect of the composition of the cement paste with respect to the water:cement ratio and mineral pozzolan content on the effective chloride ion diffusivity is investigated. The diffusivity is found to increase as the water:cement ratio increases. The

Calibration of a solid-state copper ion-selective electrode in cupric ion buffers containing chloride

, 1991
It is shown that near-Nernstian calibration slopes can be obtained with a Cu1.8Se electrode in a range of cupric ion buffers in spite of a high chloride content. Best results are obtained with the ligands ethylenediamine, glycine and histidine. The onset

Investigation of natural diffusion behavior in concrete using iodide replacing chloride ions: The impact of mineral admixtures types and dosages

Journal of Materials Research and Technology
The chloride natural diffusion (CND) test is often used in concrete-related field to analyze the chloride diffusion behavior in concrete and chloride diffusion coefficient (D(Chloride)) is an important parameter for durability assessment of RC structures.
