The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Concrete surfaces that are coated or treated with sealers may not provide an acceptable electrical circuit. No further reproductions authorized. The sponge may be folded around and attached to the tip of the reference electrode aztm that it provides electrical continuity between the porous plug and the concrete member.

Calomel reference electrodes have been used in laboratory studies. 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.
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 or high salinity enviroment and large amounts of carbon dioxide CO 2processes known as chloride penetration and carbonation respectively [1,2,3].
Given the importance of preserving civil structures, is evident the strong necessity of obtaining a system with great flexibility to perform the estimation in situ of the corrosive state, capable to dispose the information for immediate consultation anywhere with minimum internet access.

Concrete cover in excess of 3 in. Historical Version s – view previous versions of standard. 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.
