Honestly, you're better off just freezing the beams the normal way. It isn't that hard once you get the hang of it. Just jump to the low platform, wait for the bottom beam to go, then jump to the right side. As the beam comes at you again, freeze it and jump on it. The next beam will soon come at you, do a small jump and hit it with the concrete and then jump on it. Rinse and repeat for the third beam, and you're home free.

Also note that if you hit a beam that is starting to thaw with the concrete, it will freeze again. This is useful if the beam you are standing on starts to thaw, as it will buy you a few extra seconds (assuming the beam coming at you from the side doesn't kill you first).
