For example, the carbonation resistance of concrete with a cement with only 15 mass % limestone was equal to that of a cement with 30 or even 50 mass % limestone when the w/c ratio was reduced from 0.5 to 0.35 or 0.3 (Figure 3). Of course, sophisticated process measures in cement plants are necessary for the production of high-limestone cements.
Limestone is usually added to pipes carrying purified water. The limestone works to increase the alkaline levels of these pure waters, at the same time restoring the essential mineral levels. This helps to protect the pipes from corroding. 24.) Protecting Lakes. Man-made freshwater lakes tend to be vulnerable to acidic rains.
