EVERY PRODUCER AND contractor wants to eliminate the discrepancies in results they experience when testing fresh and hardened concrete. One of the best ways to reduce differing test results, and even eliminate poor cylinder breaks, is to ensure that technicians conduct the tests according to the procedures outlined in the referenced ASTM International document.
Ensuring that your quality control technician is properly trained has become a lot easier. Last month, ASTM launched a new web initiative focused on standards training. While in time, this new product will be developed for many ASTM standards, the initial offering includes training on common construction material tests.
David von Glahn, ASTM's director of product development, unveiled the program at ASTM's June meeting in San Diego. ASTM's goal is to provide an educational tool for the users of the standards. von Glahn says the standards training gives guidance on what is published about how the committee intends for the procedures to be conducted.
Standard Training Modules are created under the direct supervision of accredited professionals and ASTM staff. Each module is then reviewed by voting members of the appropriate ASTM committee and selected industry professionals who work with the standard.
Setting the foundation Video standards training is not new. For more than a decade, John and Susan Schemmel have been pioneers in providing these visual resources to the concrete industry through their company, eTEC LLC. ASTM recently purchased eTEC from the Schemmels, and is now offering the eTEC training videos to an international community in these new packages. "We plan on using this strong foundation and expanding it to our entire ASTM network," says von Glahn.
The ASTM programs just released are focused on concrete. The standards training teaches lab and field technicians, inspectors, and quality control technicians the proper procedures outlined in several ASTM standards commonly used to test fresh and hardened concrete samples. But just as important, it's a useful tool to help other employees, such as drivers and foremen, know procedure basics, recognize inconsistencies, and alert supervisors if something doesn't look correct.
ASTM can also customize training modules to meet the training needs of large companies. The ASTM eTEC platform is useful for those seeking a costeffective, comprehensive tool and for those preparing for ACI certification or staying current between certifications.
