cement powder is a single parameter that is meant to characterize the specific surface area and therefore the fineness of cement [13]. The relationships among these different representations depend on particle shape and, in case of mass, density [3]. There is a potential to optimise conventional cement clinker grinding

However, when regarding gases, density is largely affected by temperature and pressure. An increase in pressure decreases volume, and always increases density. Increases in temperature tend to decrease density since the volume will generally increase. There are exceptions however, such as water's density increasing between 0°C and 4°C.
