When limestone filler is used as a cement replacement, the effective w/c ratio is the main variable affecting ion transport. Therefore, a low proportion (<10%) of limestone filler causes no significant changes in the sulfate resistance of the parent Portland cement, whereas a large proportion (>15%) may worsen sulfate performance.

Limestone is a common type of carbonate sedimentary rock.It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes have likely been more ...
