Corrosion of Reinforcing Bars in Concrete
The causes and mechanisms of corrosion of reinforcing bars in concrete are described in terms of the practical issues as well as the electrochemistry. The parameters affecting corrosion are (i) the ingress of aggressive species, such as chlorides, which break down the protective film on the reinforcing bar and (ii) the amount of those species necessary to do so. The former is largely controlled...
متن کاملEffect of Reinforcing Bar Contamination on Steel-Concrete Bond During Concrete Construction
Synopsis: During concrete construction, form oil, bond breaker, concrete splatter and other types of contaminants often contaminate reinforcement. Current specifications and quality control measures require the removal and clean up of these contaminants before the placement of concrete due to a concern of a reduction in bonding capacity. This is costly, labor intensive, and may not be necessary...
متن کاملSegmentation of buried concrete pipe images
The enormity of the problem of deteriorating pipeline infrastructure is widely apparent. Since a complete rebuilding of the piping system is not financially realistic, municipal and utility operators require the ability to monitor the condition of buried pipes. Thus, reliable pipeline assessment and management tools are necessary to develop long term cost effective maintenance, repair, and reha...
متن کاملRapid Tooling for Producing Stretch-formed Jewelry
In this paper, Computer Aided Designing (CAD) in conjunction with Rapid Tooling is applied to design and produce forming tools (punch and die) for stretch-formed jewelry (generated on thin sheet metal on top of which jewelry patterns are raised with forming tools by stretching the sheet metal beyond its elastic limit. The work presents a parametric voxel based CAD paradigm for modeling of such ...
متن کاملAn extended framework of cages formed of pre-synthesised and functionalised heterometallic cages.
We present the first example of an extended 3D framework synthesised without the use of an isolable organic component. This is achieved by the combination of two cage complexes isolated and functionalised prior to synthesis; [(n)Pr2NH2][Cr7NiF8(O2C(t)Bu)14(O2CC5H4N)2] and [Fe2CoO(O2C(t)Bu)6(HO2C(t)Bu)3], where the former is as a bidentate linker, bridging between three nodes of the latter.
