Limestone floors are a timeless tradition and can even be found in the pyramids. Known for its ability to last for extremely long periods of time, limestone has a wide array of benefits that are associated with it when it comes to use in construction projects. One thing limestone.Coarser limestone powder contained SCCs. When higher limestone powder content (i.e., 20 by weight of cementitious materials) and longer curing age (i.e., 90 days) were used, the two limestone powder types had similar water penetration, rapid chloride penetration, and rapid migration results. over, when 3 micron size limestone powder was used,.Nov 09, 2015 Limestone today serves one key role which cannot go unmentioned.
