The test can also be used to ensure that materials used in new construction are free from potentially harmful chloride ion levels. With this method, the concentration of acid soluble chlorides is measured. In most cases, this is equivalent to total chloride concentration. A sample of powder is obtained by drilling and careful quartering. Then an accurately weighed 3gm. sample is dissolved in 20 ml of extraction liquid which consists of a precise, measured concentration of acid.
For sampling wet concrete a 3gm sample of mortar (i.e. without coarse aggregate) is used. Typically for concrete, samples that are to be analyzed for chloride are obtained at various depths, thereby supplying the engineer with a chloride ion profile.
