Will the cement board rust?
Reinforced concrete cement board pouring density is good, long-term bubble in the water will not rust cracking.
Time if long-term, of course, can be imagined that ordinary cement is a portland cement, urine containing hydrochloric acid, after a long period of time into the hydrochloric acid will produce corrosion of cement will be metamorphosed in advance, it must be affected.
