the and reacts with hydroxides, such as calcium hydroxide, to form carbonates. In the reaction with calcium hydroxide, calcium carbonate is formed: Ca(OH) 2 + CO 2 → CaCO 3 + H 2O This reaction reduces the pH of the pore solution to as low as 8.5, at which level the passive film on the steel is not stable. Carbonation is generally a slow process.

Calcium Nodules – Pool Help

Although the size of a nodule is mostly a function of the available calcium reactants in a void or crack, the shape of a nodule is dictated by environmental forces. When they form on horizontal surfaces, the nodules tend to be round and “volcano” in shape. But of they form on a vertical surface, they may be in a drip, or stalagtite shape.
