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. Corrosion monitoring of steel in concrete by galvanostatic pulse technique. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

This standard is not included in any packages. 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 corrosion results, and environmental exposure conditions, in addition to corrosion — measurements, to formulate conclusions concerning corrosion activity of embedded steel and its probable effect on the service life of a structure.

Concrete surface in building interiors and desert environments lose sufficient moisture so that the concrete resistivity becomes so high that special testing techniques not covered in this test method may be required see 5. No further reproductions authorized.

cc876 Alert me to new issues of Meet. Current edition approved Nov. 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 a 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.

It is ast, necessary to use other data such as chloride contents, depth of carbonation, delamination survey findings, rate of corrosion results, and environmental exposure conditions, in addition to corrosion potential 0, to formulate conclusions 0 corrosion activity of embedded steel and its probable effect on the service life of a structure.

Therefore, the present work shows the development and implementation of a system for in situ monitoring of corrosion, for any reinforced concrete structure based on ASTM C [5] standard for measuring half-cell potential, with which it is possible to determine the corrosion probability of rebar in reinforced concrete structures.
