Chloride binding in GGBS concrete
267
TL;DR: In this article, the results of chloride binding measurements of GGBS pastes, as well as chloride diffusion and permeability measurements of concrete mixes were reported, and it was found that chloride binding capacity was increased with increasing GGBS replacement levels and the chloride exposure concentration.

Developing chloride resisting concrete using PFA
TL;DR: In this paper, the authors investigated the effect of the intrinsic permeability of concrete and the ability of its cement matrix to bind chlorides on the coefficient of chloride diffusion in concrete.

Microstructure and durability of mortars modified with medium active blast furnace slag
TL;DR: In this paper, a Granulated Blast Furnace Slag with a low reactivity index is used in modifying mortar composition, and the results indicate a finer porosity and lower water absorption for slag mortars at old ages (90 and 360 days).

Chloride Adsorption by Calcined Layered Double Hydroxides in Hardened Portland Cement Paste
Seyoon Yoon,Juhyuk Moon,Sungchul Bae,Xiaonan Duan,Emmanuel P. Giannelis,Emmanuel P. Giannelis,Paulo José Melaragno Monteiro +6 more
TL;DR: In this paper, the feasibility of using calcined layered double hydroxides (CLDHs) to prevent chloride-induced deterioration in reinforced concrete was investigated and shown that they not only adsorbed chloride ions in aqueous solution with a memory effect but also had a much higher binding capacity than the original layered double hydrides (LDHs) in the cement matrix.

Physically and chemically bound chlorides in hydrated cement pastes: a comparison study of the effects of silica fume and metakaolin
TL;DR: In this article, the characteristics of hydration products were widened by introducing silica fume and metakaolin into Portland cement pastes, respectively; then, the consequent chloride binding capacity was followed using Freundlich binding isotherms; chemically and physically bound chlorides were further distinguished.

Corrosion initiation of reinforced concretes based on Portland or GGBS cements: Chloride contents and electrochemical characterizations versus time
TL;DR: In this article, the ingress of chlorides in cylindrical reinforced concretes based on ordinary Portland cement (OPC) or ground granulated blast furnace slag cement (GGBS) was investigated together with the corrosion behaviour of the steel rebar.

Chloride binding capacity and binding isotherms of OPC pastes and mortars
Tang Luping,Lars-Olof Nilsson +1 more
TL;DR: In this paper, a method for evaluating the chloride binding capacity of concrete was proposed based on the adsorption from solution and chloride binding isotherms of OPC pastes and mortars with water-cement ratio 0.4, 0.6 and 0.8.
Diffusion of chloride ions in hardened cement pastes
C.L. Page,N.R Short,A. El Tarras +2 more
TL;DR: In this paper, the activation energies for the diffusion process have been measured and the results have been related to the pore structures of the materials and the influence of certain other factors, including the curing conditions, the presence in the samples of interfacial zones of segregation and the use of several other types of cement, have also been examined.

Interaction of chloride and CSH
TL;DR: In this paper, the chloride binding properties of synthetic CS-H preparations having a wide range of C/S and H/S ratios were examined and a mechanism for chloride interaction compatible with the Feldman and Taylor models was suggested.

Chloride binding in cement II. The influence of the hydroxide concentration in the pore solution of hardened cement paste on chloride binding
TL;DR: The influence of various factors on the binding of chloride in cement and the chloride concentration of the pore solution was investigated in this paper, where it was shown that pore solutions of samples prepared under addition of chloride taken from the same cement and with identical content of total chloride exhibited different chloride concentrations only, if their hydroxide concentrations diverged.

The binding of chloride ions by sulphate resistant portland cement
TL;DR: In this article, the role of the tetra-calcium aluminoferrite (C 4 AF) phase of the ordinary portland cement was investigated and it was concluded that the chlorides in SRPC are bound in the form of the chloro-complex C 3 F.
