Hi
In our project, we have proposed that a material be made to break the adhesion around the anchor bolts. If anyone has done this type of application before, I would be grateful if they could provide information on the material they used.

Projemizde, ankraj bulonlarının etrafında aderansı kırmak için bir malzeme yapılmasını önermiş. Aranızda bu tür uygulamayı daha önce yapmış olan varsa kullandıkları malzeme konusunda bilgi verebilirse memnun olurum.

Why not just use a pvc sleeve or something? Whats the purpose of not having them adhered?

Engineer accepted DENSO TAPE but is not bond breaker. İt is coorrision protection tape.

I have used galvanized or plastic sleeves in the past, but have also used DENSO too. Whilst DENSO is primarily a corrosion protection 'tape', it will also be a bond breaker is you apply 2 or more layers, because the petrolatum-tape is easily deformable.

Are you pre-loading the anchor rods, and hence the bond breakers?

Also, you need to be careful with the anchor rod/bolt couplers. The couplers will need to accommodate movement to maintain the bond breaking you wish to achieve.
