Link to Active This link will always route to the current Active version of the standard. Your Alert Profile lists the documents that will be monitored. Experiments and Results It was obtained a system for in situ monitoring of corrosion for reinforced concrete, that allows to estimate the corrosion probability on rebar, where the user send adtm text message, to start the test in the system and in return, via GPRS General Packet Radio Servicethe equipment disposes the data trend on a graphic trough a web server on an internet domain figure 1.
If the document is revised or amended, you will be notified by email. It is often necessary to use other data such as chloride contents, depth of carbonation, delamination survey findings, rate of aetm results, and environmental exposure conditions, in addition to corrosion potential measurements, to formulate conclusions concerning corrosion activity of embedded steel and its probable effect on the service life of a structure.
Already Subscribed to this document. For concrete submerged in seawater, using silver-silver chloride reference electrodes avoids chloride contamination problems that may occur with copper-copper sulfate electrodes.
