Limestone Vertical Cement

Properties and behavior of limestone cement concrete and ...

01/10/2000  Limestone cement concretes indicate lower resistance to freezing and thawing compared with the pure cement concrete. Portland limestone cement, containing 20% limestone, shows the optimum protection against rebar corrosion. Furthermore, the limestone additions decrease the carbonation depth and the total porosity of the mortar.

Performance Enhancer for Portland Limestone Cement (PLC)

In practice, portland-limestone cement is ground to a higher fineness compared to portland cement. An increase of Blaine in the range of 100cm 2 /g is necessary to compensate for the strength reduction resulting from the addition of 1% limestone. 3 The mill type and process system play an important role.
