I was looking for a way to reinforce a 1" copper tubing feeder I made. Concrete would be cheaper, but trying to pour concrete into a 1 inch diameter pipe would be difficult and messy. The tensile and flexural strength of epoxy is also much higher than that of concrete. I simply put a funnel on top of the pipe and filled it with West System 105 and 205 hardener, which is what makes epoxy the strongest. The feeder is now much stiffer, probably like 1" galvanized pipe or better. It's filled just below the bottom feeder arm, but I'll fill the rest just after drilling drainage holes in the highest part of the arms, which I'll temporarily tape over once the epoxy runs out of the holes. Now I have to figure out how much to mix.
