The filler effect of LS is mainly related to its particle size. The calculated packing density of mixtures containing cement, slag and LS is illustrated in Fig. 1 [25].It can be seen from Fig. 1 (a) that the packing density of mixtures is lower when the particle size of LS is coarser or comparable to Portland cement, whereas the packing density is higher …

Limestone, a kind of natural mineral resource, is a sedimentary rock formed by inorganic remains such as shells or bones. And people always see it in warm and shallow water fields.

Density of Limestone. Typical densities of various substances are at atmospheric pressure. Density is defined as the mass per unit volume.It is an intensive property, which is mathematically defined as mass divided by volume: ρ = m/V In words, the density (ρ) of a substance is the total mass (m) of that substance divided by the total volume (V) …

The mixtures used in this study were prepared with Portland cement CEM I 52.5. Limestone powder, produced from carboniferous limestone of a very high purity (98% of CaCO 3 content), was added as filler. The density of limestone powder was 2650 kg/m 3. The chemical properties of the cement and limestone powder used are …
