 · The traditional method for determination of total chloride content in a concrete sample is "acid-soluble chloride extraction" [18,19,20]. Extraction of total chloride content using this method may not end with release of all the bound chlorides. Therefore, the total chloride content of the sample can be underestimated . The part of bound ...

Sea water contains 30,000 ppm I've left 100s of miles of subsea pipeline with saltwater hydrotest inside for up to 6 months. 30 years later, still flowing gas. Independent events are seldomly independent.

The chloride content limit is the amount of chloride that must be present in concrete along with oxygen and moisture in order to facilitate corrosion. Table-1 below shows the ACI 318-95 code limits of water soluble chlorides. ... Acid …

chloride ion per cubic yard. When tested by the acid-soluble test method, the amount is taken as 0.20% chloride ion by weight of cement, or for the same cement content, 1.2 pounds of chloride ion per cubic yard. To understand the rationale for the proposed revisions, let's first look at the limits in the current code require- ments.

 · "1.5 Procedure C covers the determination of organic chloride in the washed naphtha fraction of crude oil by X-ray fluorescence spectrometry." This is an important step forward, as users will be able to officially use XOS' Clora, Clora 2XP, and Sindie +Cl analyzers for organic chloride analysis in crude oil without ASTM method modification.

 · The initial chloride content was verified by measuring the acid soluble chloride content in accordance with ASTM C1152. The water-soluble chlorides were measured at an age between 28 and 42 days in accordance with ASTM C1218, as required by ACI 318-14. In each case, the measured water-soluble chlorides were less than the initial calculated ...

The test for acid-soluble chlorides (ASTM C 1152) treats crushed material with nitric acid rather than water. Almost all of the chlorides present in the concrete are detected, whether they are bound or are available to cause corro-sion. Because the test method finds all chlorides, limits based upon acid-soluble chloride content are higher than

 · Finally, it can be seen in the figure that the effect of chloride content in mixing water on total chloride is minimal to moderate up to a w / c equal to 0.4. The critical amounts are the amounts of aggregates; therefore, it is essential to precisely control …

Cl2 (chlorine) is a very potent oxidizer (reason it kills bacteria) and therefore high levels of Chlorine may accelerate chloride corrosion of stainless steels. 304 and 304L, 321 SS may be used for "water applications" with up to 2 ppm chlorine, while 316 and 316L alloys may "take" up to 4 ppm. If looking for information about Chlorine ...

 · For C1 with the mean chloride content is well in excess of 0.01%, the repeatability and reproducibility standard deviations are 0.0017 and 0.0179% respectively. The repeatability standard deviation is within the same range as 0.0015% reported in the ASTM C1152 - Standard Test Method for Acid-Soluble Chloride in Mortar and Concrete.
