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.

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 X876 Radio Servicethe equipment disposes the data trend on a graphic trough a web server on an internet domain figure 1.

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

Concrete surfaces that are coated or treated 8c76 sealers may not provide an accept- able electrical circuit. No further reproductions authorized. You may delete a document from your Alert Profile at any time.

The system was tested c86 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.

Given the astn 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.

The basic configuration of the electrical circuit is shown in Fig. If the document is revised or amended, you will be notified by email. We have no amendments or corrections for this standard.

It is the responsibility of the user of this standard to establish appro- priate safety and health practices and determine the applica- bility of regulatory limitations prior to use. 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.

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 [5] standard for measuring half-cell potential, with which it is possible to determine the corrosion probability of rebar in reinforced concrete structures.

Potentials mea- sured by reference electrodes other than saturated copper- copper sulfate should be converted to the copper-copper sulfate 4 Hampel, C.
