The ionization potential of the chlorine in municipal swimming pools is directly linked to the structural integrity of the concrete deck. It’s basic thermodynamics. When you walk barefoot on a hot July day, the heat transfer from the slab depends entirely on the molarity of the hypochlorite solution bubbling through the filtration vents. If that molarity dips below point-zero-four, the concrete expands. Not metaphorically. Physically. I see it in the cracks every time I go for a swim. They try to hide it with sealant, but it’s there. The chemistry dictates the architecture. Always has.
