We are currently designing an indoor pool (3'to 6'-6' deep)and have been mulling around ideas with regards to the concrete mix. Currently the pool is proposed to be shotcreted and have 8" thick walls with integral foundations and 6" slab. We are considering a 4000 psi mix with a W/C of 0.45 (564# cement content, no fly ash) and specifying that the concrete supplier provide shrinkage test results to verify the mix has 0.04 to 0.03% shrinkage. I was also considering an admixture made by Xypex (C-500) that reacts with moisture in fresh concrete and causes a catalytic reaction that generates a crystalline formation waterproofing.
Anyone have any thoughts or recommendations from their experiences?
Thanks in advance.
