Dear all,

I need your help, I want to test fibre reinforced polymer bars under tensile to calculate the tensile strength of bars. For FRP bars we can't grip bars in jaws directly such as steel bar, because FRP bars have very low compressive strength and FRP will crush at jawss at very low load and test will stop. That is why ACI440 recommend us to anchorage the ends of FRP bars, then tensile test will be carried out and failure will occur by rupture FRP bars, nor crushing at jaws.

Anchorage will conduct by using steel tubes at the two ends of FRP bar.

Please to make anchorage I need expansive cementitious grout to fill the gap between FRP bars and steel tube, If any one know supplier in UK or Europe, please tell me.

Regards,

Najia
