Carport using unusual construction method

So.....No rebar.
Right, no rebar. I think the cement-filled pipe through the center of the pillar, plus the cement bonding/fortifying agent that I am using, make it quite strong. The fortifying/bonding agent results in a product quite different from cement in which only water is used to wet the mix.

As I said earlier, there is a lot less wobble in the supporting structure of this build, prior to adding the rafters and sheathing, than there is in a conventional frame build, signifying that the completed build will have less wobble than a frame build would have.
