    An evaluation of bonding agents used in concrete bridge reconstruction
    (University of New Brunswick, 1991) McInnis, Gary; McKim, R.; A., McKim
    This senior report evaluates the effect of bonding agents used to bond together the fresh concrete layer to the repaired concrete surface . The bonding Agent evaluated in this report is Sicadur 32 HI-MOD a two part epoxy structural adhesive.lt was evaluated using the ASTM C-2 34 1986 for comparing bond development of concretes, varying only the bonding conditions instead of concrete type. The results of the testing show a marginal increase in bond development with an epoxy bonding agent used for immediate pour ,and when recoated after a 24hr hardening time. Form the results of this report it can be concluded that Bonding agents marginally increase bond development if used under proper conditions , but will decrease the bond development, if applied improperly.
