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. You may delete a document from your Alert Profile at any time.

Potentials mea- sured by reference electrodes other than saturated copper- copper sulfate should be converted to the copper-copper sulfate 4 Hampel, C. Need more than one copy? Significance and Use 4. 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  standard for measuring half-cell potential, with which it is possible to determine the corrosion probability of wstm in reinforced concrete structures.
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 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.

This standard is not included in any packages. For concrete submerged in seawater, asrm silver-silver chloride reference electrodes avoids chloride contamination problems that may occur with copper-copper sulfate electrodes.

It shall consist of a sponge or several sponges pre-wetted with a low electrical resistance contact solution. Concrete surfaces that are coated or treated with sealers may not provide an acceptable electrical circuit. Add to Alert PDF. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The occurrence of such phenomena represents mostly the durability problems of the material, especially when the structure is subjected to the chloride ions presence in marine f876 high salinity enviroment and large amounts of carbon dioxide CO 2processes known as chloride penetration and carbonation respectively [1,2,3].
