Corrosion Resistance Performance of Fly Ash Blended Cement Concretes
Durability of reinforced concrete with respect to corrosion of reinforcement is one of the major aspects to be considered in the management of civil infrastructure systems. An accelerated laboratory test method developed at SERC where the concrete specimen containing rebar is subjected to polarization under a constant voltage in a sodium chloride solution. It is found that the current response ...

15 صفحه اولCalcium Orthophosphate Cements and Concretes
In early 1980s, researchers discovered self-setting calcium orthophosphate cements, which are a bioactive and biodegradable grafting material in the form of a powder and a liquid. Both phases form after mixing a viscous paste that after being implanted, sets and hardens within the body as either a non-stoichiometric calcium deficient hydroxyapatite (CDHA) or brushite, sometimes blended with unr...
متن کاملBlended Learning on Campus
On the basis of a large-scale project implementing information and communication technology at Roskilde University, Denmark, this paper discusses ways of introducing technologybased blended learning in academic life. We examine some examples of use of systems for computer-mediated collaborative learning and work in Danish Open University education as well as in courses on campus. We further sug...
