Chloride diffusion assessment in RC structures considering the stress-strain state effects and crack width influences
(2019-03-20)
The aim of this study is to investigate the chloride ions diffusion in sound and cracked concrete under compressive loads. The model includes the analytical setup and data analyses. The governing equations are modified to ...
Calibration of boundary conditions correlated to the diffusivity of chloride ions: An accurate study for random diffusivity
(2022-02-01)
For reinforced concrete (RC) structures, the corrosion of the reinforced steel bars from chloride ions is a periodic risk. The chloride ions diffusion is governed by Fick’ laws, however, these equations can be applied under ...
RCM: A new model accounting for the non-linear chloride binding isotherm and the non-equilibrium conditions between the free- and bound-chloride concentrations
(Elsevier, 2012-01)
In this paper a new theoretical model for the Rapid Chloride Migration test is presented. This model accounts for the non-linear chloride binding isotherm and the non-equilibrium conditions between the free- and bound-chloride ...
2D/3D Numerical Analyses of Corrosion Initiation in RC Structures Accounting Fluctuations of Chloride Ions by External Actions
(2021-06-01)
The diffusion of chloride ions in reinforced concrete (RC) varies in space and time, depending on many uncertain factors as material properties, temperature, aging, humidity and external loadings. In this paper, the goals ...
Approximation by the Finite Element Method to the Preferential Chloride Diffusion through Interfacial Transition Zone in Concrete
(Planta Piloto de Ingeniería Química, 2011-07)
Chloride diffusion in concrete is a main aspect of reinforced concrete durability. It defines the time required for reinforcement corrosion in marine structures. Concrete porosity is one of the main concerns involved in ...
Diffusion of nitrite and nitrate salts in pork tissue in the presence of sodium chloride
(Wiley Blackwell Publishing, Inc, 2002-08)
The objective of the present work was to analyze the effect of NaCl concentration on the diffusion coefficients of NaNO2 and KNO3 in pork tissue using unsteady techniques. Concentrations of nitrite and nitrate as a function ...
Surface treatment of reinforced concrete in marine environment: Influence on chloride diffusion coefficient and capillary water absorption
(ELSEVIER SCI LTD, 2009)
There are currently many types of protective materials for reinforced concrete structures and the influence of these materials in the chloride diffusion coefficient still needs more research. The aim of this paper is to ...
Reducing Water and Chloride Penetration Through Silicate Treatments for Concrete as a Mean to Control Corrosion Kinetics
(ELECTROCHEMICAL SCIENCE GROUPBELGRADE, 2013-08-02)
There are currently many types of protective materials for reinforced concrete structures and the influence of these materials in the chloride diffusion coefficient and water penetration still needs more research. The aim ...
High-volume fly ash concrete with and without hydrated lime: Chloride diffusion coefficient from accelerated test
(2013)
Fly ash changes the microstructure of paste and can increase concrete durability. Calcium hydrated lime was added to concrete
with 50% of the cement, by weight, substituted with fly ash, with the intent of replacing some ...
