I'm adding to an existing fence on my property and I've decided to do away with treated 4x4 fence posts. The replacement will be 4 1/2" x 5 1/2" x 10 1/2' concrete posts. They'll be 3 1/2' deep in the ground so that gives me about 7' above ground.

If any of you have any experience in structural engineering please take a look at my concrete mix and rebar distribution and tell me what you think.

The post uses a low slump 1:2:2 mix (cement:sand:gravel) with the gravel screened to 3/4" or finer. Four 1/4" rebars are put in, 3/4" beneath the surface of the post, running the whole length, and arranged at the corners of the cross section of the post.

Thanks in advance.
