Also, if you're adding plastics to concrete, wouldn't that mean that it is inherently weaker in that it should theoretically deform easier? This could be faulty logic though... but it just seems
Idk... I don't think you should wrap it, I think that that will serve very little purpose because you will only have the shearforces on the inside of the tube and outside of the concrete as opposed to implanting the threads which would then increase the friction and therefore increase the amt of loading
Okay... umm these results should be better I think....
My reasoning is that type III concrete, from experience, usually has a break of 6500-7500 psi at 28 days and around 3000 on 1-2 day breaks... That being said, why you didn't use type II is beyond me.
If you're only getting 4600 to 6100, could you be mixing wrong?
Could the carbon fiber wrap be preventing the full cure of the concrete?
Wouldn't rebar just be superior? Granted I guess you would be using this in special enviroments
1:50 Save your self the time. Also the camera man should have set the camera down on a chair to record this instead of jumping when the specimen failed :(
Our control specimen was able to hold 129000 tons, and our CFRP(above) was able to hold approximately 173000 tons. That means 4600 psi and 6100 psi respectively.

What would have been the nominal fail force before carbon fiber reinforcement?
