Although the steel–concrete interface (SCI) is widely recognized to influence durability of reinforced concrete, a systematic overview and detailed documentation various aspects SCI are lacking. In this paper, we compiled comprehensive list possible local characteristics at reviewed available information regarding their properties as well occurrence in engineering structures laboratory. Given complexity SCI, suggested approach describe it terms physical chemical properties. It was found that...
Available experimental investigations on the effect of aggregate–paste ‘interfacial transition zone' (ITZ) mass transport properties cement-based materials appear to be ambiguous. While some studies have found a deleterious ITZ, results from others seem suggest otherwise. The present study examines relative influences ITZ and microcracking oxygen diffusivity, permeability water sorptivity, further enhance understanding links between microstructure properties. Specimens several neat cement...
Abstract The potential of conventional superabsorbent polymers (SAPs) based on partially neutralised acrylate and acrylate/acrylamide copolymers as an admixture for self-sealing cracks in concrete is investigated. SAPs are cross-linked that can absorb a disproportionately large amount liquid swell substantially to form soft insoluble gel. However, their swelling capacity highly dependent the alkalinity ionic content solution. These characteristics may be exploited concrete. In this...
Abstract The corrosion of steel reinforcement in concrete structures induced by chloride ion contamination is a major problem. Deterioration starts with the loss protection provided cover as result ingress. This followed initiation and then propagation. Recent advances models penetration into concrete, based on mathematical physical transport processes an analysis empirical data, have been made. Inhibitive aggressive properties solid phases present at which affect identified. Improved...
