Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being limesecreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone.

Compressive strength vs. fine/coarse limestone powder. Phase assemblage. The volume amount of CSH and hemi and monocarboaluminate phases determined by mass balance approach is plotted at 1, 3 and 28 days in Fig. 10. The highest amount of CSH is observed with PC. For all ages, a similar CSH amount is obtained between the two mixes ...

177 Accesses Metrics Abstract The effects of ordinary limestone powder (OLP) and ultrafine limestone powder (UFLP) on the fluidity, setting time, compressive strength, hydration heat and microstructure of calcium sulfoaluminate cement (CSA) were investigated. The results show that finer limestone powder reduces the fluidity and setting time of CSA.

Limestone powder (LS) has been widely used in cementbased materials; and reportedly, can influence their properties by filler, nucleation, dilution and chemical effects. The action mechanism of LS mainly depends on its particle size and amount. The filler effect of LS refines the microstructure and reduces the porosity of cementbased materials.

In addition, very fine limestone powder (H3L2055) is less effective than the average limestone powder (H3L2000). As expected, the highest limestone content (40%) provides the lowest flexural strength at 1 day (H3L2055, H5L2055 and H7L2055). In particular, a low content of coarse silica fume (3%) showed better results in terms of the ...
