This study presents the decision-making support process by means of AHP method to be applied to select optimal patching repair materials for chloride-deteriorated concrete member.
The result of the study shows that this method is the useful and rational engineering approach in the problem concerning the selection of one out of many candidate repair materials even if this study was limited to repair material only for chloride-deteriorated concrete.
The present study investigates the influences of forming-materials for the chloride ion penetration of seashore concrete made by with fly-ash and silica fume.
By plotting phase velocity curves and group velocity curves of plane waves and Rayleigh surface wave for a viscoelastic material (polyvinyl chloride foam), the influence of the fractional order of viscoelasticity is examined.
Two months ago, the commission confirmed that it had opened an investigation into companies that supply raw materials for making polyvinyl chloride plastic, including Akzo Nobel and TotalFinaElf.
Therefore, it makes the hypotheses of Fick's laws acceptable for chloride ingress modelling, because, in this case, the material is assumed completely saturated, with unidirectional chloride flux, i.e., from the exterior surface into the concrete depth.
Maeda et al. (2004) also developed empirical expressions for chloride diffusion coefficients of ordinary Portland cement with or without supplementary cementing materials.
The prospect of power outages is also a boon for Chloride, which provides uninterruptible supply services.
However Emerson said today it was spending $1.2bn for technology group Avocent Corporation, making a new bid for Chloride unlikely.
Herein, chloride ion-doped polyaniline/carbon nanotubes (PANI/CNTs) composite materials, which were prepared by an in situ chemical oxidative polymerization method using FeCl3·6H2O as the oxidant, have been developed as new cathodes for chloride ion battery.
