Cement is a dispersed solid whose particle size is ranging from 0.1 to 250 micron-meter. *For example, if the particle size of a material is described as -4 +40 mesh, then 90% or more of the material will pass through a 4-mesh sieve (particles smaller than 4.76 mm) and be retained by a 40-mesh sieve (particles larger than 0.420 mm).
