Limestone powder is one of the major ingredients used in construction materials but also has many other uses in daily life. Limestone powder, also known as limestone flour or limestone dust, is a finely ground powder obtained from the sedimentary rock called limestone. It is produced by crushing and grinding limestone rocks into a powder form.
