Abstract Introduction Corrosion of concrete rebar has been established as the main factor of the premature deterioration of reinforced concrete structures.
A number in parentheses indicates the year of last reapproval.

Concrete surfaces that are coated or treated with sealers may not provide an acceptable electrical circuit. Standards Subsctiption may be the perfect solution. Concrete surface in building interiors and desert environments lose sufficient moisture so that the concrete resistivity becomes so high that special testing techniques atsm covered in this test method may be required see 5. 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.

International Journal of Electrochemical Science. Originally approved in 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.
Concrete cover in excess of 3 in. The sponge may be folded around and attached to the tip of the reference electrode so that it provides electrical continuity between the porous plug and the concrete member. 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 atsm 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.

Given the importance of preserving c786 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.

Already Subscribed to this document. 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 x876 rebar in reinforced concrete structures.
