Lab Quality
HeidelbergCement Georgia’s construction materials testing laboratory has been accredited under international ISO 17025:2010 standard since 2015. This standard means high quality performance and high level of personnel qualifications, introduction of best international practices accumulated over the course of the past decades, which eventually guarantees maximum accuracy and reliability of lab tests. Georgia Accreditation Center carries out an annual inspection of work processes with a view to controlling the quality of the laboratory work and the personnel’s qualification is checked through direct observation of concrete tasks performed by them. The lab’s regulatory framework is also inspected; Georgian Accreditation Center checks how well the activities are registered, results logged and formalized, besides, accuracy of use of modern equipment and devices and their compliance with standards is checked as well. Normative documents are updated on an annual basis. Besides, HeidelbergCement’s Global Competence Center Materials (CCR) performs a detailed inspection of the lab activities and provides technical assistance to it.

• In order to further improve the work processes, construction materials testing methods are periodically compared with laboratories accredited in Georgia as well as international laboratories. In Europe we have a close cooperation with Netherlands-based KOAC-NPC laboratory, which provides identical test materials to various labs, ensures the processing of results and provides the laboratories involved in the testing process with test results.
• A mobile laboratory is a special vehicle equipped with all necessary devices, it is used for testing air content in the concrete mixture, its consistence (slump) and temperature right at the construction site. Besides, the mobile laboratory can take the slurry samples at the construction site, cut out bars from the reinforced concrete frame and define the strength of the hardened concrete using the scratch hardness testing (unbreakable) method.
Laboratory
Our laboratory checks the materials used for concrete production and defines their operability, we use materials for concrete production only after that process is complete, whether it’s sand/crushed stone, cement or various types of plasticizers. We perform the quality control of concrete both in the factory and at construction sites. The main parameters checked are: breaking load (strength), consistence (slump), temperature, air content and water-resistance. The mobile laboratory provides services to our customers right at the construction site. Samples are molded at the construction site, they are marked with special label that contains the following data: site name, address, design parameters of the concrete and date of molding. The label is signed by the construction site representative and pasted over the concrete sample in order to ensure its accurate identification. We test all the parameters that may be tested in the concrete mixture during the molding process: slump, temperature, air content; besides, samples are taken in order to establish their subsequent hardness (strength).
Concrete samples are stored in the special storage room where they are kept in water at 20±2°C. Hardness tests are carried out at the 7th and 28th days after production based on EN 206-1 standard.
