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.

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. We have no amendments or corrections for this standard.

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

The basic configuration of the electrical circuit is shown in Fig. For concrete submerged in seawater, using silver-silver chloride reference electrodes avoids chloride contamination problems that may occur with copper-copper sulfate electrodes. 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.

Your Alert Profile lists the documents that will be monitored. No further reproductions authorized.

Concrete surfaces that are coated or treated with sealers may not provide an acceptable electrical circuit. Corrosion of concrete rebar has been established as the main factor of the premature deterioration of reinforced concrete structures.
