Use Of Limestone In Cement Production

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.
