HI everyone ,
I would be really grateful if an expert in chemical anchors can answer my question.
I use Fischer vinyl ester hybrid mortar- FIS V plus 300 T. I used M8 bolt/ anchor in a 8 cm deep hole with sufficient mortar. The curing time is about 45 min according to manual. After about 2 hours without applying torque i applied about 100 kg downward tension and the anchor was stable. Around 30 min after that i used a nut to remove some left over mortar on the anchor threads and when i try to remove the struck nut with about 1 to 2 Nm torque the anchor was spinning freely. I was not able to remove nut with hand so i used pliers to hold the anchor and then removed the nut. After about 1 hour i inserted the fixture , washer and bolt and tightened to 10 Nm. To my surprise the anchor was tightened and i heard click from the torque machine. I thought i stripped the bond between the anchor threads and the resin around it. I looked on the internet but cant find any info. AI studio says anchor or bond is not damaged and said i just caused torsional rotation, but i dont trust the answer. Is my anchor really safe just because it tightened at 10 Nm torque ?
