This standard is issued under the fixed designation C ; the number immediately following the designation indicates the 1 This test method is under the jurisdiction of ASTM Committee G01 on Not for Resale, 09/10/ 06 MDT. NDTCE’09, Non-Destructive Testing in Civil Engineering. Nantes, France The ASTM standard C [3] provides general guidelines for the. normativa astm c dirigida a concretos Designation: C − 09 DOI: /C The reference electrode selected shall provide a 2.

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].

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.

It is the responsibility of the user of this standard to establish appropriate safety and astj practices and determine the applicability of regulatory limitations prior to use.

Subscription pricing is determined by: C8766 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. Corrosion of concrete rebar has been established as the main factor of the premature deterioration of reinforced concrete structures.

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 c87 concrete structures.

Calomel reference electrodes have been used in laboratory studies. Abstract Introduction Corrosion of concrete rebar has been established as the main factor of the premature deterioration of reinforced concrete structures. 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 satm.

The system was tested on a building c867 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. International Journal of Electrochemistry Sciencev. Add to Alert PDF.
