Thor, or should that be Zeus?

Hi Chaz
I hope this is going to be OK, the cross section is very thin and if you haven't placed rebar in that lot i envisage problems(hope not)

Mike

Hope so too. The main section is fairly thick (200mm), the ribbing is for extra support. Those are 50mm wide.

Have you got any images of the final design you settled on Chaz?

50mm thick UHPC is pretty strong!

Ill upload some. I need to rethink the gantry. I need to use less concrete. The plastisizer cost a fortune ...

Polycarboxylate is the normal liquid superplasticizer. The shop I just linked seem to be pretty good and reasonably priced.

I'm going to try them out for some of my own experimentation.

Looks similar to what I am using but mine is a bit lighter. Same idea however.

Chaz is the colour from the super plasticer or have you added pigments.? Also expected that you would have added fibres.?

Jazz, the cement is white. Snowcrete (basically). The stone is black and the sand then, well brown. The plastisizer is a light colour .... I suspect most of the colour is the mix of sand and cement.

I did not add fibres. It was discussed (with the guy providing me bits) and in his past experience it was pain to do and he did not feel worth it.

The ribs won't add any strength without rebar. the mix for small cross sectional beams/lintles ect is 3parts aggregate(10mm) 2 parts sharp sand 1 poart cement. but you still need the rebar.
i feel really bad about this as i should have mentioned it earlier.
But you seem to have gone into it in detail as you have with the rest of the build.

No problem. Lets see how it holds out.
