Potential of finely ground limestone powder to benefit ...

Finely ground limestone powder was hypothesized as a potential filler to help minimize these negative aspects when used as either a partial or full mass replacement of similarly sized cement and silica powder. Limestone powder was shown to have a positive effect on fresh properties of the composite including mixing time and workability.

Study on Properties of Blended Finely Ground Limestone ...

The effect of replacement of Portland cement by ground limestone as well as its specific surface Blaine (SSB) on the physical-mechanical properties of fresh and hardened cement paste is studied. The binder was composed of cement and limestone, which was prepared by eight replacement levels of limestone powder (0,5,10,15,20,25,30 and 35%) of binder by mass and four levels of SSB …
