2.) Blow the hole clean using a hand pump or compressed air 4 times minimum.
3.) Brush the hole with the proper wire brush 4 times minimum.
4.) Blow the hole clean using a hand pump or compressed air 4 times minimum.
5.) Fill the hole up to approximately 2/3 with adhesive.
6.) Push the rebar into the hole while turning slightly.
7.) Allow the adhesive to cure for the time specified for the actual concrete temperature prior to applying any load.

dESIGN INfOrmaTION
• The following information is meant to give the designer aid in the preliminary design process. No responsibility is taken for the correctness of the data.
• Reinforcement bars installed by AC100-PRO adhesive proved as good as cast-in reinforcement bars. For this reason their design complies with the concrete design approach which basically determines the anchorage length required to transfer a given design load from the reinforcement bar into the concrete.
• For further details and background information please see the introduction of this manual and to the respective design codes.
