I had ordered decorative concrete for the tower back in April, it didn't get here until the 27th, I'm hoping we can get that on when I go home for 3 weeks on the 4th.
I had a guy build the tower last year, I was on the slope and he missed one little detail on it...he didn't put in the rebar stub ups for the dome roof, they are supposed to be lap spliced with the vertical rebar in the tower walls, no way to get it fixed exactly as it is supposed to be. I spent some time contemplating what I would do, I though of everything from timber frame domes to copper clad silo domes. I finally contacted the engineer and asked what he would do. He gave me a detail for a MD dome that would be a bit lighter than the original design. I found there is a place down in the states that has a wet shotcrete mix that is 8500 psi @ 28 days and uses all fine aggregates. I was thinking this would be a good thing to bring the strength back to the roof and I could pump it with a little pump I own, it won't pump any aggregate over 1/4 inch. I ordered some of that but just recently found out the plant didn't ship it, so, if I am going to get it done this fall, I'm back to a regular 8 sack mix and renting a real shotcrete set up. That company also claims to make a dry shotcrete mix that is 14,400 psi and uses all fine aggregates.
