ASTM C876 - 09 PDF

Shakagul 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. Abstract Introduction Corrosion of concrete rebar has been established as the main factor of the premature deterioration of reinforced concrete structures. Potentials aztm sured by reference electrodes other than saturated copper- copper sulfate should be converted to the copper-copper sulfate 4 Hampel, C. The basic configuration of the electrical circuit is shown in Fig. Please first log in with a verified email before subscribing to alerts.

International Journal of Electrochemistry Sciencev. Originally approved 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.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. The system was tested on a building of the University complex, where its performance c evaluated using three different reference electrodes, obtaining an error over the measurement, between the standard and the system, of 6.

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.

Experiments and Results 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 Asmt General Packet Radio Servicethe equipment disposes the data trend on a graphic trough a web server on an internet domain figure 1.

Concrete surface in building interiors and asgm environments lose sufficient moisture so that the concrete resistivity becomes so high that special testing techniques not covered in this test method adtm be required see 5. 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.

For concrete submerged in seawater, using silver-silver chloride reference electrodes avoids chloride contamination problems that may occur with copper-copper sulfate electrodes.

Current VolumeMA 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 ashm high salinity enviroment and large amounts of carbon dioxide CO 2processes known as chloride penetration and carbonation cc [1,2,3].

Concrete surfaces that are coated or treated with sealers may not provide an accept- able electrical circuit. 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.
