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.

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 ...
