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.
Features & Benefits:
• Fast – Results within minutes at the site • Economical – Low cost per sample compared to laboratory testing • Accurate – Results are comparable to laboratory testing • Covers wide range from 0.002% to 2% chloride by weight • Internal Memory to store readings for later upload to a PC via USB • Digital display for direct reading of percentage of chloride by weight • Conforms to AASHTO-T- 260
Hylec Controls | Test Equipment Suppliers and Integrators
Hylec Control was first established in 1979 and initially started operation as a developer and manufacturer of analogue control systems. These were specially customised hydraulic applications, using servo valve technology. Hylec inarguably acclaims to be one of a few companies that have the knowledge and experience to service and repair most servo brands past and present.
Today, Hylec while still maintaining their core business in supply and service of quality servo valves also provides the latest equipment for the Test, Measurement, Construction, Building, Automotive & Aviation industries.
We welcome you to a snapshot of some of the latest technology available today.
