Concrete cover in excess of 3 in. Concrete surfaces that are coated or treated with sealers may not provide an acceptable electrical circuit.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

A number in parentheses indicates the year of last reapproval. The system was tested on a building of the University complex, where its performance was evaluated using three different reference electrodes, obtaining an error over the measurement, between the standard and the system, of 6.

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 potential measurements, to formulate conclusions concerning corrosion activity of embedded steel and its probable effect on the service life of a structure. This standard is not included in any packages. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

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.

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.

The sponge may be folded around and attached to the tip of 0 reference electrode so that it provides electrical continuity between the porous plug and the concrete member.
