Experimental Study and Numerical Analysis of Chloride Ion Diffusion in Hydrotalcite Concrete in Chloride Salt Environment

open access: yesMaterials, 2023
Hydrotalcite, known as layered double hydroxides (LDHs), is a new type of admixture used to delay the corrosion of reinforcement. The aim of this study was to investigate the chloride ion diffusion behavior of C30 concrete with varying amounts of ...

Correlation Between Chloride Ions’ Migration and Diffusion Coefficients of Alkali-Activated Concrete

2023
Alkali-Activated Materials (AAM) are considered an alternative to cementitious binders. Due to the reduction of Portland cement content and using industrial wastes to produce it, AAMs gained the researcher’s interest in the last decades. Current researches show that mechanical properties and ability to ensure proper conditions for reinforcing steel of ...

The difference in chloride ion diffusion coefficient of concrete made with drinking water and wastewater

Construction and Building Materials, 2020
Abstract In this study, the chloride ion penetration of concrete made with drinking water and domestic wastewater of the anaerobic pond (non-potable water) were evaluated through the experimental tests and finite difference method. We considered three mix designs with water to cement ratios between 0.4 and 0.6 for each category.

Experimental Study on Chloride Ion Diffusion in Concrete Affected by Exposure Conditions

open access: yesMaterials, 2022
The transport mechanism of chloride ions in concrete is relatively complicated since the erosion process is influenced by many factors. To investigate the effect of exposure conditions on the chloride ion diffusion property, three exposure conditions ...

The Slice-Resistivity method to measure the chloride ion diffusion coefficient of cementitious materials

Construction and Building Materials, 2020
Abstract Most of the existing experimental and research methods for the diffusion of chloride ions in cement-based materials use an applied electric field test method with electrodes, which are unable to eliminate the effect of polarization. In this study, the relationship between resistivity and chloride ion diffusion coefficient (CIDC) is ...

Measurements of tracer diffusion coefficients of lithium ions, chloride ions and water in aqueous lithium chloride solutions

Journal of the Chemical Society, Faraday Transactions 1: Physical Chemistry in Condensed Phases, 1987
Tracer diffusion coefficients of lithium ions, chloride ions and water in aqueous lithium chloride solutions over a wide range of concentrations at 298.2 K have been determined by means of the diaphragm-cell method using 6Li, 36Cl and 2H as tracers.

Seasonal Variation of Surface Chloride Ion Content and Chloride Diffusion Coefficient in a Concrete Dock

Advances in Structural Engineering, 2013
Concrete powder collected in-situ from a 5-year-old concrete dock in four seasons respectively was tested by rapid chloride test (RCT). Based on Fick's second law, the surface chloride ion content and the chloride diffusion coefficient are derived by regression analysis, and the seasonal variation laws of the two parameters are discussed.
