Effect of lime mud under wet grinding on the

For some fillers used in mortar, like limestone powder, more nucleation sites for C-S-H gels might generated from the higher fineness [21], which was easy to access through wet grinding. However, the reaggregation of CaCO 3 happens with the rapid raise of slurry viscosity during the process, which limits the maximum fineness [22].

Limestone can also be chemical in origin as is the case with travertine. Chemical limestone forms when calcium and carbonate ions suspended in water chemically bond and precipitate from their aquatic sources. Because of its high calcium content, limestone is usually light in color, although many variations exist.
