We have no amendments or corrections for this standard. 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] c86 for measuring half-cell potential, with which it is possible to determine the corrosion probability of rebar in reinforced concrete structures.

Abstract Introduction Corrosion of concrete rebar has been established as the main factor of the premature deterioration of reinforced concrete structures.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. For concrete submerged in seawater, using silver-silver chloride reference electrodes avoids chloride contamination problems that may occur with copper-copper sulfate electrodes.

As the voice of the U. 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 Serviceawtm equipment disposes the data trend on a graphic trough a web server on an internet domain figure 1.

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.
