It appears that calcium carbonate grows in chlorinator chambers, which shows that CaCO3 is not affected by Cl2. Other components in cement may react with chlorine, though.

Would you happen to know what other components of cement will react with CL2 (hyrdation of cement)? Do you think it will affect the properties of cement, like strength?

Well, wouldn't wet chlorine react with calcium carbonate?

H20 + Cl2 => HCl + HClO

HCl + HClO + CaCO3 => Ca(ClO)2 + Ca(Cl)2 + H2O + CO2

I did some research and did not find any reaction, but that doesn't mean one cannot occur. I wonder if HClO is a strong enough acid to react with CaCO3.

Carbonic acid is a stronger acid than HClO, and CO2 can be used to make chlorine water with calcium hypochlorite (containing CaCl2).
