Portland cement?

HI, I have been reading about Portland Cement and was wondering your thoughts. It had been written that it can cause fatigue from standing on it as it draws out the energy just like it can drain a car battery. Also has been known as "new barn" syndrome for animals. German employers actually cut out the cement where their employees stand and put a different product to not cause the fatigue.

I read that you could troll or spray on Magnesium based cement over the portland to help mitigate this issue and put 4 inches of pre-crushed chips like Durisol or Faswall low-density fiber cement over fine gravel before you pour the Portland cement to give it a cushion to allow the Portland cement to dry out.

Also, I have read that if a person puts xps foam underneath the basement slab, it can cause mold because it takes so long for the portland cement to dry out. Is this a possibility?
Would putting a foot of small pebbles under the foam be wise and maybe 6" of sand on top of the foam.

I just am looking for some clarification.
