I realise this is an old video, so chances are that I wont get an answer. I don't really understand the test results here. Fiber reinforcements can increase the tensile strength because of the fibers high tensile strength. But as far as I know, the compressive strength of the composite will be the same as the matrix material, in this case concrete, since normal stress modes don't allow the fibers to take on the compression load. Care to elaborate?

wow doesn't conventional concrete fail at like 50,000 lbs?

Good stuff.

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.
