Corrosion monitoring of steel in concrete by galvanostatic pulse technique. The basic configuration of the electrical circuit is shown in Fig. User Name Password Sign In. Standards Subsctiption may be the perfect solution. Enviado por Roberta flag Denunciar.

Current edition approved Nov. 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.

We have no amendments or corrections for this f876. No further reproductions authorized. It is often necessary to use other data such asym chloride contents, depth of carbonation, delamination survey findings, rate of corrosion results, and environmental exposure conditions, in addition to 099 potential measurements, to formulate conclusions concerning corrosion activity of embedded steel and its probable effect on the service life of a structure.

The system was tested on a building of the University complex, where its aztm was evaluated using three different reference electrodes, obtaining an error over the measurement, between the c8876 and the system, of 6. 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 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. Concrete cover in excess of 3 in. Corrosion of concrete rebar has been established as the main factor of the premature deterioration of reinforced concrete structures. 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.

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.

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 d876 as chloride ast and carbonation respectively [1,2,3]. This standard is not included in any packages. 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.

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.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

Concrete cover in excess of 3 in. Potentials mea- sured by reference electrodes other than saturated copper- copper sulfate should be converted to the copper-copper sulfate 4 Hampel, C. 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.
