Durability of steel reinforced concrete in chloride environments: An overview
TL;DR: In this article, the authors report recent advances in the knowledge base relevant to the durability of steel reinforced concrete in chloride environments, including: the role of mineral admixtures in concrete durability, the methods of measuring the chloride ingress into concrete, the challenges in assessing concrete durability from its chloride diffusivity, and the service life modeling of reinforced concrete.

Chloride binding of cement-based materials subjected to external chloride environment – A review
TL;DR: In this article, the authors reviewed the chloride binding of cement-based materials subjected to external chloride environments and proposed four different types of binding isotherms to describe the relationship between free and bound chloride.

Effect of supplementary cementing materials on concrete resistance against carbonation and chloride ingress
TL;DR: In this paper, the durability of Portland cement systems incorporating supplementary cementing materials (SCM; silica fume, low and high-calcium fly ash) is investigated.

The effect of supplementary cementitious materials on chloride binding in hardened cement paste
TL;DR: In this article, the effects of supplementary cementitious materials (SCMs) on the chloride binding of portland cement pastes were investigated. And the binding relationships were best described by the Freundlich isotherm and binding coefficients were given for all the binders tested.

State-of-the-art applications of fly ash from coal and biomass: A focus on zeolite synthesis processes and issues
TL;DR: In this paper, the authors discuss the key factors affecting zeolite synthesis, primarily from coal fly ash; the drawbacks of each approach are also analysed, and the characterization and potential applications of these materials are analyzed in detail through reference to the numerous studies published on fly ash worldwide over the last number of decades.

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.
The reaction of fly ash in concrete a critical examination
TL;DR: In this paper, a model for the formation of pozzolanic reaction products and the development of the pore structure is presented, and a critical examination of the "incubation period" is given.

Stability of Friedel's salt in carbonated concrete structural elements
TL;DR: In this article, the role of atmospheric carbonation on the stability of Friedel's salt in chloride contaminated concrete slabs was investigated and it was shown that the solubility of the salt increases with the degree of carbonation of the concrete.

The c1-/oh- ratio in chloride-contaminated concrete - a most important criterion
O. A. Kayyali,M.N. Haque +1 more
TL;DR: In this article, free chloride and hydroxyl ion concentrations in the pore solutions of the concretes were determined and the value of free chloride content by itself cannot provide a meaningful indication of the susceptibility of the reinforcement to chlorideinitiated corrosion.
