Portland cement clinker is normally black and the appearance of a paler than usual product has in the past been taken to suggest excessive chemical reduction of Fe3+ in the kiln However Scrivener and Taylor found significant reduction in some black samples of clinker and perhaps more surprisingly they also found that a lighter colour did not necessarily mean that reduction had occurred
9 Density and Specific Gravity • Density is the mass of a unit volume of the solids or particles excluding air between particles The particle density of Portland cement ranges from 3 10 to 3 25 Mg/m3 averaging 3 15 Mg/ m3 • It is used in concrete mixture proportioning calculations • For mixture proportioning it may be more useful
