When we need to extend or adding up a story of concrete floor above existing structure, we need to plant the dowel bars or connector bars above the existing reinforced concrete column. The steel reinforcement or rebars is to ensure for safe compression loads. A reverse testing ie pull out force test could determine the bonding strength of new plant rebars with old concrete.

On site testing to determine the starter bars installation compliance to the required pull out forces as per parent material strength.
The installation and setting up is fast and the instant results are reliable and conclusive.
Overall testing is fast, reliable and should be practice on site as a simple compliance to meet the minimum material specification requirements.
