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.

Influence of fly ash on the water and chloride permeability of alkali-activated slag mortars and concretes
Idawati Ismail,Idawati Ismail,Susan A. Bernal,Susan A. Bernal,John L. Provis,John L. Provis,Rackel San Nicolas,David G. Brice,Adam R. Kilcullen,Sinin Hamdan,Jannie S.J. van Deventer +10 more
TL;DR: In this article, the authors investigated the properties of slag mortar and concretes with partial fly ash substitution and showed that the chemistry of the binding gels significantly controls the mass and ionic transport in chloride-containing environments.

Hydration and rheology control of concrete for digital fabrication: Potential admixtures and cement chemistry
TL;DR: In this article, the main required concrete states for extrusion and deposition processes are analyzed with respect to required performances and potential admixtures, and possible side effects and incompatibilities are discussed, as well as how they could be unconventionally used for printable concrete purposes.

Concrete: An eco material that needs to be improved
TL;DR: In this paper, the authors examined some of the routes that may be followed to further improve the environmental performance of concrete, which is the largest volume material used by man and is irreplaceable for innumerable large infrastructure developments.
Journal ArticleDOI
The effects of polypropylene fibers on the properties of reinforced concrete structures
TL;DR: In this article, the compressive strength, permeability and electric resistivity of concrete samples were studied using polypropylene fibers reinforced concrete properties, and it was concluded that the coral aggregates are not suitable for making concrete or using in concrete structures in the onshore atmosphere.

Electrochemical Polarization I . A Theoretical Analysis of the Shape of Polarization Curves
Milton Stern,A. L. Geary +1 more
TL;DR: In this paper, a linear dependence of potential on applied current is described for a corroding electrode by treating it in a manner analogous to that for a non-corroding electrode, and an equation is derived relating the slope of this linear region to the corrosion rate and Tafel slopes.

Corrosion of steel in concrete
TL;DR: In this article, the authors present a research work that aims at mapping out the various mechanisms which control the process of steel corrosion in concrete, and illustrate how steel corrosion is illustrated.

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.

Expression and analysis of pore fluids from hardened cement pastes and mortars
R.S. Barneyback,Sidney Diamond +1 more
TL;DR: In this article, a device is described that has been used for several years for expression pf pore solution from hardened portland cement pastes and mortars, and methods for the analysis of the resulting small volumes of pore solutions are briefly discussed.
